Takisha conducted an experiment to determine the effect of salt on the boiling point of water. She measured the boiling points of 100 ml of water with salt added in 5 g increments. As a control, she also recorded the temperature of water with no salt added. What is the purpose of this control?.

Answers

The control provides a reference value for comparison to samples in which a variable is changed.

What effect does salt have on the experiment with water boiling point?Giddings said that the presence of salt makes it more difficult for water molecules to escape from the pot and transition into the gas phase, which occurs when water boils. Salted water has a higher boiling point as a result.

What happens if you experiment with adding salt to water?When salt is added to water, the water becomes denser. Salt provides bulk to the water as it dissolves in it (more weight to the water). By making the water denser, more items that would normally sink in fresh water can float on the surface.

What does salt and water come to?Since salt water heats up more quickly and reaches its boiling point first, it will boil more quickly than pure water. When pure solvent (in this case, water) and a dissolved material (salt) are combined to form a solution, boiling elevation point occurs (the salt water).

ammonia, an important source of fixed nitrogen that can be metabolized by plants, is produced using the haber process in which nitrogen and hydrogen combine.n2(g) 3h2(g) → 2nh3(g)how many grams of nitrogen are needed to produce 325 grams of ammonia?

Answers

Using a stoichiometric calculation, it was determined that 178.43 grams of nitrogen are needed to produce 325 grams of ammonia.

We can use a simple stoichiometric proportion to calculate this. First, we write the reaction:
[tex]N_{2} + 3H_{2}[/tex] → [tex]3 NH_{3}[/tex]

We can see that 1 mole of nitrogen produces 2 moles of ammonia.

Nitrogen's molar mass is 2 * 14 = 28 g/mol.

The molar mass of ammonia is 14 + 3 * 1 = 17 g/mol.

Based on this and the reaction equation, we can say that 28 grams of nitrogen produce 3 mol * 17 g/mol = 51 g of ammonia.

Now, we make a proportion:

28 g of nitrogen : 51 g of ammonia = X : 325 g of ammonia

X = 28 g of nitrogen * 325 g of ammonia / 51 g of ammonia = 178.43 g of nitrogen

Answers

The volume of the substance with mass of 54mg and density of 1.2g/mL will be 0.045 mL.

How much "stuff" is contained in a specific quantity of space is determined by its density. For instance, a block of the harder, lighter element gold (Au) will be denser than a block of the heavier element lead (Pb) (Au). Styrofoam blocks are less dense than bricks.

Mass per unit volume serves as its definition.

We know that, Density = mass of substance / volume of substance

Given,

mass = 54 mg = 0.054 g

Density = 1.2g/mL

Need help finding the moles on this question ?

Answers

In areaction, the number of moles consumed and produced have the same ratio as the coefficients on the balanced equation.

So, to calculate the number of moles of any chemical on the reaction given the number of moles of any other, we can use a rule of three.

We put the compound or atom we want on the first column and the one we have information of on the second, and their coefficients on the second row:

We want Al and we have information about Al₂O₃, and their coefficients on the balanced equation are 4 and 2, so:

Al --- Al₂O₃

4 2

Now, we use thise placements to write the equation:

[tex]\frac{n_{Al}}{4}=\frac{m_{Al_2O_3}}{2}[/tex]

Where the n stands for the number of moles. Now we solve for Al:

[tex]\begin{gathered} \frac{n_{Al}}{4}=\frac{m_{Al_2O_3}}{2} \\ n_{Al}=4\frac{m_{Al_2O_3}}{2} \\ n_{Al}=2m_{Al_2O_3} \end{gathered}[/tex]

And since we know the number of moles of Al₂O₃, we have:

[tex]\begin{gathered} n_{Al_{2}O_{3}}=0.800mol \\ n_{Al}=2n_{Al_{2}O_{3}} \\ n_{Al}=2\cdot0.800mol \\ n_{Al}=1.600mol \\ n_{Al}\approx1.60mol \end{gathered}[/tex]

Where the last step we did an approximateion to get to 3 significant figures.

So, the number of moles of Al consumed is 1.60 mol.

A typical frostless refrigerator uses 655 kWh of energy per year in the form of electricity. Suppose that all of this electricity is generated at a power plant that burns coal containing 3. 1% sulfur by mass and that all of the sulfur is emitted as SO2 when the coal is burned.


If all of the SO2 goes on to react with rainwater to form H2SO4 , what mass of H2SO4 is produced by the annual operation of the refrigerator? ( Hint : Assume that the remaining percentage of the coal is carbon and begin by calculating ΔH∘rxn for the combustion of carbon. )

Answers

The annual operation of the refrigerator produces 6835.5 g of sulfuric acid. This calculation is made assuming that the enthalpy of combustion for sulfur is equal to the enthalpy of combustion for carbon.

First, we are going to transform 655 kWh into kilojoules. Because 1 kWh = 3.6e6 J = 3600 kJ, that means that a typical frostless refrigerator uses 655 * 3600 kJ = 2358000 kJ of energy on a yearly basis.

The enthalpy of combustion for carbon (or enthalpy of carbon dioxide formation) is -393 kJ/mol. That means that we can calculate the number of moles of carbon needed to produce 2358000 kJ of energy.

2358000 kJ / 393 kJ/mol = 6000 mol of carbon

Because the molar mass of carbon is 12 g/mol we need

6000 mol * 12 g/mol = 72000 g of carbon

If 3.1% of this carbon is actually sulfur, then we will burn 0.031 * 72000 g = 2232 g of sulfur during one year. The molar mass of sulfur is 32 g/mol, which means we transformed 2232 g / 32 g/mol = 69.75 mol of sulfur into sulfur dioxide and further into sulfuric acid. Because 1 mol of sulfur is needed to produce 1 mol of sulfuric acid, we produced 69.75 moles of sulfuric acid.

The molar mass of sulfuric acid is 98 g/mol, so over the course of one year, we produced 69.75 mol * 98 g/mol = 6835.5 g of sulfuric acid.

when 4.14 moles of ibr gas is initially injected into a 1 l container at 150 c, the kc for this reaction is 8.5 calculate the equilibrium concentration of i2

Answers

By using the expression for the equilibrium constant for the reaction and solving the appropriate quadratic equation, we can calculate that the equilibrium concentration of iodine will be 1.77 M.

The balanced reaction equation for this reaction looks like this:

[tex]2 IBr[/tex] → [tex]I_{2}+Br_{2}[/tex]

The expression for the equilibrium constant will look like this:

[tex]K_{c} =\frac{[I_{2} ][Br_{2} ]}{[IBr]^{2} }[/tex]

Because all the volumes are the same, we can just use the moles of all reaction components instead of concentrations. Now, because there was no iodine or bromine when the reaction began, all iodine and bromine present at equilibrium are formed by IBr decomposition, their concentrations will be the same (X). The concentration of IBr will be reduced by 2X, so we can plug that into the equilibrium constant expression:

[tex]8.5=\frac{X^{2} }{(4.14-2X)^{2} }[/tex]

We transform this expression to get a quadratic equation:

33X² - 140.76X + 145.6866 = 0

When we solve for X, one solution is 2.49 M (which is impossible, because 4.14 moles of IBr can create a maximum of 4.14 mol / 2 = 2.07 mol of iodine), and the other (correct) solution is 1.77 M.

The production of silver grew over the centuries, but when Europeans first went to America, silver began to be used in many new and different ways. By the 19th century, nearly 120 million troy ounces were being produced annually. Now, more than 5000 years after ancient cultures first began to mine this precious metal, an average of 671 million troy ounces is mined every year. In earlier times, silver was thought to have magical properties and it was considered to be useful in keeping bad spirits away. Nowadays, most people think of silver in relation to ornaments. But it is significant for its antibacterial properties too. The ancient Phoenicians kept water, wine and vinegar in silver vessels to ensure freshness. It is only recently, however, that scientists have discovered how silver works. Quite simply, silver destroys the ability of bacteria to form the chemical bonds which are essential to their survival. When bacteria and silver come into contact, the bacterial cells fall apart. Today, there are bandages and ointments that use silver as an active ingredient. Silver promotes the growth of new cells, which in turn increases the rate of healing. This makes silver especially valuable for treating burns and wounds. Another key use for silver is in the millions of water purifiers that are sold each year. Silver prevents bacteria from building up in filters so that they can work effectively. Research has shown that silver, together with oxygen, cleans water. This means that other chemicals, such as chlorine, do not have to be used. Silver is therefore starting to be added to water purification systems in hospitals, community water systems and swimming pools. Scientists hope that silver will be able to be used in helping to produce clean drinking water in countries where water-borne illness is a problem. Current research shows that this use of silver is an exciting development for the global water supply. In the past, silver was often used to decorate places of worship, and many people saw it when they went to pray. Today, there is probably much more silver around us, but we do not necessarily see it. For example, every time you travel in a motor vehicle you are surrounded by pieces of silver. Every electrical action in a modern car is activated with silver-coated contacts. Basic functions such as starting the engine and opening power windows .all need a special switch that has a silver covering. Another important feature for our driving safety is the silver-ceramic lines fitted into the rear window. The heat created by these lines clears the rear window of mist and ice so that we can see clearly out of it. Silver is just as valuable today as it has been throughout human history.
