Charle's Law. Volume is directly proportional to the absolute temperature when pressure is constant.
QveST [7]3 years ago
4 0

<u>Answer:</u> The correct answer is Charles' law.

<u>Explanation:</u>

There are 4 laws of gases:

  • <u>Boyle's Law:</u> This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

P\propto \frac{1}{V}     (At constant temperature and number of moles)

  • <u>Charles' Law:</u> This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

V\propto T     (At constant pressure and number of moles)

  • <u>Gay-Lussac's Law:</u> This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

P\propto T     (At constant volume and number of moles)

  • <u>Avogadro's Law:</u> This law states that volume is directly proportional to the number of moles of the gas at constant pressure and temperature.

V\propto n   (At constant temperature and pressure)

Hence, the correct answer is Charles' law.

Which option accurately describes the first two stages of photosynthesis?
Lemur [1.5K]

Answer;

A) Stage 1: Chlorophyll captures light energy. Stage 2: Light energy is converted to chemical energy.

Explanation;

-Photosynthesis is the process by which green plants use energy from the sun, water and carbon dioxide to make organic compounds such as simple sugars together with release of oxygen.

-The process occurs in tow stages; light-dependent stage and light independent stage. During light dependent stage, chlorophyll absorbs sunlight and uses it to split water molecules into hydrogen ions and oxygen atoms. In the light independent stage carbon (iv) dioxide is fixed and the result is organic compound; the light energy is converted to chemical energy.

Calculate the final molarity of HCl the resulting solution when 5.56 mL of 4.108 M HCl is added to 4.44 mL of water.
puteri [66]

The final molarity of HCl is 2.284 M

We'll begin by listing what was given from the question. This is shown below:

Initial volume (V₁) = 5.56 mL

Initial Molarity (M₁) = 4.108 M

Final volume (V₂) = 5.56 + 4.44 = 10 mL

<h3>Final Molarity (M₂) =? </h3>

The final molarity of the HCl solution can be obtained by using the dilution formula as illustrated below:

<h3>M₁V₁ = M₂V₂</h3>

4.108 × 5.56 = M₂ × 10

22.84048 = M₂ × 10

Divide both side by 10

M₂ = 22.84048 / 10

<h3>M₂ = 2.284 M</h3>

Therefore, final molarity of the HCl solution is 2.284 M.
