Answer 2

Thermal energy is represented in the units joules J. It is the energy needed to raise the temperature by one degree celsius.Per gram this energy is called as specific heat capacity with the unit J/°Cmol.

What is heat capacity?

Heat capacity of a substance is the heat energy required to raise the temperature of the substance by one degree celsius.

If the heat capacity is measure per one mole of a substance it is called specific heat capacity. It is an intensive property whereas heat capacity is an extensive property.

The given passage can be completed as follows:

The unit often used in chemistry and physics to measure energy, such as for work or electrical current, is Joule (J). We can also use this unit, as we did in this lab, for measuring  heat capacity.  

This is a property that is quantified by the energy needed per one gram of material to raise the temperature by one degree celsius.The unit for this measure is therefore J/°Cg.

Answer:

1) The mole ratio of KClO₃ to 3O₂ is 2:3

The reciprocal of the mole ratio of KClO₃ to 3O₂ is 3:2

2) The mole ratio of K to NaNO₃ is 1:1

The reciprocal of the mole ratio of K to NaNO₃ is 1:1

Explanation:

The mole ratio (also known as mole-mole ratio) of two compounds involved in a chemical reaction, is the ratio of the number of moles of the compounds in the reaction which can be obtained from the coefficients of the compounds in the balanced chemical reaction

The mole ratio of compound A to compound B = A:B = A/B

1)The given chemical reaction can be expressed as follows;

2KClO₃ → 2KCl + 3O₂

Therefore;

[tex]The \ mole \ ratio \ of \ KClO_3 \ to \ O_2 = \dfrac{2 \ moles \ of \ KClO_3}{3 \ moles \ of \ O_2} = \dfrac{2}{3} = 2:3[/tex]

[tex]The \ reciprocal \ of \ the \ mole \ ratio \ of \ KClO_3 \ to \ O_2 = \dfrac{3 \ moles \ of \ O_2}{2 \ moles \ of \ KClO_3} = \dfrac{3}{2} = 3:2[/tex]

2) In the reaction NaNO₃ + K → Na + KNO₃

The mole ratio of K to NaNO₃ = 1:1

Therefore;

The reciprocal of the mole ratio of K to NaNO₃ = 1:1

Do you
think that the Nitrogen cycle has a negative or positive
impact on the environment?

Answers

Answer:

Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air, we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils, and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.

give an example of how an organism can use surface tension?

Answers

Answer:Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.

Explanation:

Answer:

Examples of surface tension Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.

Answers

Please give me brainleist. :)

Answer:

2a. If the temperature is increased, the reaction will shift to the right in an attempt to release some of the heat. As the forward reaction loses heat while the reverse would create more heat.

2b. If the pressure is increased, it would shift to the left to counteract the increase in pressure as the left side will have fewer molecules.

2c. If Cl2 is added the reaction will shift to the left in order to remove the stress of the extra Cl2 and favor the production of more reactant.

2d. If PCl3 is removed, the reaction will shift to the right. When part of the equation is removed the reaction learns to adapt to the loss by trying to make more Pcl3 and counteract the effects of losing the PCl3.

3a. The reaction will shift to the right to produce more heat and counter the negative effects of losing the heat.

3b. It will shift to the left to get rid of the excess HCl being produced and form more reactant from the breakdown of the HCl.

3c. It would shift to the right in order to get rid of the excess form products from it.

3d. If pressure is decreased there will be no effect on the shift of the reaction because there is an even amount of moles of gas on each side.

4a. K=[N2O4(g0] / [NO2(g)]2

4b. (Below)

K=[N2O4(g)] / [NO2(g)]2

0.4 / 0.5(2)

0.4/0.25 = 1.6

Keq= 1.6

Answers

Answer:

To determine how many total electrons there are, add the amount of charge to the atomic number. In this case, there are fewer protons than electrons. For example, N 3- has a -3 charge which means it has 3 more electrons than a neutral nitrogen atom. Nitrogen’s atomic number is 7, therefore this ion has 10 electrons.

What is the molar mass of a sample of gas that has a density of 2.85g/L at 101kPa pressure
and 29°C? Name the law that is used to solve this problem.

Answers

Answer:71.25

Explanation:

The molar mass of a sample of gas that has a density of 2.85g/L at 101 kPa pressure and 29°C is 71.37  g mol⁻¹ and It can be solved using Ideal gas law.

What is Ideal gas law ?

The ideal gas law is an equation of state that describes ideal gases.

This equation of state relates a gas’s pressure, volume, temperature, and mass, and is very useful for describing how gases will behave in ideal conditions.

This is the most common equation of state for gases.

Ideal Gas equation ;

PV = nRT

Molar mass (Mm) = m /n

Where ;

m = given massn = number of moles

we also know,

Density (D) = m / v

Where ;

m = massv = volume

Now, Putting the formula of Molar mass and Density in ideal gas equation we get ;

Molar mass = D RT/ P

Given ;

Density = 2.85 g/LPressure = 101kpa (= 0.99 atm)Temperature = 29°C (= 302.15 K)(Gas constant) R = 0.0821

Putting all the values in  the above equation of molar mass ;

Molar mass = 2.85 x 0.0821 x 302 / 0.99

                    = 71.37  g mol⁻¹

The cotton gin is credited to the brilliant and creative American inventor Eli Whitney. Because Whitney's invention made cotton harvesting easier, it allowed farmers in the South to increase production. The cotton gin simplified the process of removing the cotton from the seeds, a process formerly done by hand.As a result, Southern plantations increased their production of cotton from 750,000 bales in 1830 to 2.85 million bales just 20 years later. Because of the increase in production, the farmers in South became even more dependent on cotton for revenue. This new reliance on cotton increased the need for slavery. More slaves were needed to farm the ever expanding cotton plantations.
