How do you separate and collect salt and water after a neutralisation reaction?

Answers

Explanation:

water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container.

How can we explain the motion of objects?

Answers

All things move based on how much mass they have and it’s relevance to gravity/distance from the ground. As objects moved, force is moving them. An example would be a wagon on a hill. If the wagon is on wheels at the top of the hill and someone uses force to make the wheels move, the wagon will roll down the hill due to inertia and other elements.

How many hydrogen atoms are there in 2.25 moles of H2CO3?

Answers

Answer:

4.5moles

Explanation:

2.25moles times 2 hydrogen atoms per one molecule

The number of hydrogen atoms present in 2.25 moles of hydrogen carbonate is 4.5.

What is a mole?

A mole of a compound is equivalent to the one formula unit of the compound. The number of atoms of each element in a mole of the compound can be given from the formula unit.

1 unit of hydrogen carbonate consists of 2 atoms of hydrogen. Thus, 1 mole of hydrogen carbonate has 2 hydrogen atoms.

The number of hydrogen atoms in 2.25 mole of hydrogen carbonate can be given as:

[tex]\rm 1\;mol\;H_2CO_3=2\;atoms\;Hydrogen\\2.25\;mol\;H_2CO_3=2.25\;\times\;2\;atoms\;of\;hydrogen\\2.25\;mol\;H_2CO_3=4.5\;atoms \;of\;Hydrogen[/tex]

Why NH2 is a bad leaving Group?

Consider that strong bases are strong nucleophiles, and thus unstable with the negative charge associated with dissociation from the molecule. Hence, strong bases are generally very poor leaving groups, but can be converted into good leaving groups that are more stable with the associated negative charge.

How much H is need to react with 6.58 g of O, in this reaction?
H2 + O2 -> H2O

Answers

Answer:

Balance the equation first

[tex]2H_{2} \ + \ O_{2} \ --> \ 2H_{2}O[/tex]

          6.58g of Oxygen gas

Divide 6.58g by molar mass of oxygen (32g/mol)

6.58/32 = 0.205625 mol

Use mol to mol ratio from looking at the coefficients of the reactants, the mol ratio of Hydrogen gas to Oxygen gas is 2:1, so for every 1 mol of Oxygen, you need 2 times the mol of hydrogen for it to make water.

0.205625 * 2 = 0.41125 mol

To get the mass of hydrogen gas needed in the reaction, turn 0.41125 mol into mass by multiplying it with Hydrogen gas's molar mass, which is 2.02 g/mol.

0.41125 * 2.02  ≈ 0.83g of H2

Litmus paper (whether red or blue) is only indicative of whether a substance is acidic or basic.

Universal indicator can tell you the approximate pH for example a substance could have a pH of 13.

A pH probe is the most sensitive piece of equipment so is more reliable. A pH probe will give you a more accurate result for example a pH of 13.2

g A student performs an experiment where gas is collected over water in an upside down graduated cylinder. If the atmospheric pressure is 739 mmHg and the level of water in the graduated cylinder is 11 cm higher than the level of the water exposed to the atmosphere, what is the total pressure of gases inside the graduated cylinder

Answers

The total pressure of gases is equivalent to 739mmH divided by the area.

How to calculate the total pressure of gases?

To calculate the total pressure of gases, the next formula can be used:

Total pressure: Force/areaTotal pressure  739 mmH/area

How to calculate the area?

The area of a cylinder is equal to 2πrh+2πr².

You can know the radio by checking the measurement of the base of the graduated cylinder. Also, you can determine the height by observing how many mm the gas is occupying. Then follow these steps:

Find out the area based on the formula provided.Replace the area in the pressure formula.Solve the formula.

What pressure is requred to contain 0.023 moles of nitrogen gas in a 4.2 L container at a
temperature of 20.°C?

Answers

Answer:

0.13 atm

Explanation:

Using the Ideal Gas Law; PV=nRT, we can rearrange to solve for pressure.

P=nRT/V

P is pressure, n is number of moles (0.023), R is a constant (0.08206 L*atm/mol*K), T is temperature in Kelvin (293.15K) and V is volume, 4.2 L.

So, plugging in;

P=(0.023mol)(0.08206L*atm/mol*K)(293.15K)/(4.2 L)

P=0.1317 atm

P=0.13 atm; multiply by 760 to get to Torr or mmHg.

Find the percent composition of water in barium chloride dihydrate. Round your answer to the
nearest whole number.

A)17%
B)8%
C)85.3%

Answers

The percent composition of water will be 15%

Percent composition

The percent composition of a component of a compound is found by dividing the mass of the component by the mass of the compound.

In other words:

Percent composition = mass of component/mass of substance x 100

In this case, the formula for barium chloride dihydrate is [tex]BaCl_2.H_4O_2[/tex]

The molar mass of the compound is 244.26 g/mol

The molar mass of the water component is 18 x 2 = 36 g/mol

Thus, the percent composition of water in the compound can be found, such that:

Percent composition of water = 36/244.26 x 100

                                      = 15% to the nearest whole number.
