Answer:
Mitochondria are the structures within cells that produce energy.
Explanation:
Mitochondria are also like the human digestive system because the digestive system breaks down food to supply the body with energy like the mitochondria breaks down food to supply the cell with energy.
Answer:
Photosynthesis can increase the pH level of the water and the reason is because it removes carbon dioxide that is present in the water.
Explanation:
Photosynthesis is a chemical process/cycle that is executed by plants by consuming carbon dioxide and releasing oxygen into the air or water.
The photosynthesis can cause the pH level of the water to rise because of the removal of carbon dioxide from the environment.
I hope this answer helps.
Answer:-
Chlorine gas is passed through a solution of flower to
<u>decolourise the flower</u>
<u></u>
Explanation:
Chlorine is used as a bleaching agent because of its oxidising nature.
This nascent "O" is highly reactive in nature and bleaches the substance that comes into its contact.
when flowers are passed through the chlorine solution , it oxidises the solution and removes the colour from the flower.
This property also made its use as water-disinfectant reagent.
Chlorination is done to make the water useful for drinking
It kills the harmful bacteria present in the water.
<span>Let's </span>assume that the gas is an ideal gas. Then we can use ideal gas equation,<span>
PV = nRT<span>
</span>Where,
P = Pressure of the gas (Pa)
V = volume of the gas (m³)
n = number of moles (mol)
R = Universal gas constant (8.314 J mol</span>⁻¹ K⁻¹)<span>
T = temperature in Kelvin (K)
<span>
The given data for the </span></span>gas is,<span>
P = ?
V = 9.5 L = 9.5 x 10</span>⁻³ m³<span>
T = (273 + 20) K = 293 K
R = 8.314 J mol</span>⁻¹ K⁻¹<span>
n = 1.2 mol
by applying the formula,
P x </span>9.5 x 10⁻³ m³ = 1.2 mol x 8.314 J mol⁻¹ K⁻¹ x 293 K
<span> P = 307705.5 Pa
P =3.08 x 10</span>⁵ Pa
<span>
Hence, the pressure of the gas is </span>3.08 x 10⁵ Pa.<span>
</span>
Answer:
B.
Explanation:
It is brittle like a nonmetal but conducts electricity and heat like a metal.
