Answer:
A.) Absorb and store
Explanation:
The reaction for photosynthesis is:
→
(reaction conditions: light and chlorophyll)
<em>carbon dioxide + water → glucose + water</em>
<em />
This means light energy is <u>absorbed</u> and <u>stored</u> as sugar molecules and energy for the plant
Therefore, the photosynthesis reaction will <u> absorb </u> energy and <u> store </u> it in the chemical bonds.
Answer:
<em><u>Glass that will sink</u></em>
- alkali zinc borosilicate with a density of 2.57 g/mL in a solution with a density of 2.46 g/mL
- potash soda lead with a density of 3.05 g/mL in a solution with a density of 1.65 g/mL
<em><u>Glass that will float</u></em>
- soda borosilicate with a density of 2.27 g/mL in a solution with a density of 2.62 g/mL
- alkali strontium with a density of 2.26 g/mL in a solution with a density of 2.34 g/mL
<em><u>Glass that will not sink or float</u></em>
- potash borosilicate with a density of 2.16 g/mL in a solution with a density of 2.16 g/mL
Explanation:
Density is the property of matter that states the ratio of the amount of matter, its mass, to the space occupied by it, its volume.
So, the mathematical expression for the density is:
By comparing the density of a material with the density of a liquid, you will be able to determine whether object will float, sink, or do neither when immersed in the liquid.
The greater the density of an object the more it will try to sink in the liquid.
As you must have experienced many times an inflatable ball (whose density is very low) will float in water, but a stone (whose denisty is greater) will sink in water.
The flotation condition may be summarized by:
- When the density of the object < density of the liquid, the object will float
- When the density of the object = density of the liquid: the object will neither float nor sink
- When the density of the object > density of the liquid: the object will sink.
<em><u>Glass that will sink</u></em>
- alkali zinc borosilicate with a density of 2.57 g/mL in a solution with a density of 2.46 g/mL, because 2.57 > 2.46.
- potash soda lead with a density of 3.05 g/mL in a solution with a density of 1.65 g/mL, because 3.05 > 1.65.
<u><em>Glass that will float</em></u>
- soda borosilicate with a density of 2.27 g/mL in a solution with a density of 2.62 g/mL, because 2.27 < 2.62.
- alkali strontium with a density of 2.26 g/mL in a solution with a density of 2.34 g/mL, because 2.26 < 2.34.
<em><u>Glass that will not sink or float</u></em>
- potash borosilicate with a density of 2.16 g/mL in a solution with a density of 2.16 g/mL, because 2.16 = 2.16
Answer: Option (B) is the correct answer.
Explanation:
It is known that Henry's law is a relation between the concentration of a gas in a liquid (solubility) and the pressure it exerts on the surface of the liquid.
According to Henry's law, the pressure of a gas is directly proportional to the solubility of the gas in a liquid.
Henry's constant is represented by the symbol
. And, mathematically it is represented as follows.
P =
where, P = pressure and C = solubility
As the pressure for the given species is the same. Hence, the standard values of solubility of the given species is as follows.
Gas Solubility
Ar 
CO 
Xe 


As, Henry's constant is inversely proportional to the solubility. Hence, more is the value of solubility lesser will be the value of Henry's constant.
Thus, we can conclude that out of the given options CO have the largest Henry's law constant (
) in water.
