In photosynthesis, the reactants are more stable than the products. However, both the products and reactants are stable. Therefo
My name is Ann [436]

Answer:

A.) Absorb and store

Explanation:

The reaction for photosynthesis is:

6CO_{2}+ 12H_{2}  O → C_{6} H_{12} O_{6}  +6H_{2} O  (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.

If you needed to make 100 mL of a 0.2 M fruit drink solution from the 1.0 M fruit drink solution, how would you do it? (Hint: Us
Studentka2010 [4]

Answer: We take 20 ml of 1.0 M fruit drink and add 80 ml of water to get 100 ml of 0.2 M solution.

Explanation:

According to the neutralization law,

M_1V_1=M_2V_2

where,

M_1 = molarity of stock solution = 0.2 M

V_1 = volume of stock solution = 100 ml

M_2 = molarity of resulting solution = 1.0 M

V_2 = volume of resulting solution = ?

Now put all the given values in the above law, we get the volume of resulting solution.

(0.2M)\times 100=(1.0M)\times (V_2)

V_2=20ml

Therefore, the volume of 1.0 M required is 20 ml.

We take 20 ml of 1.0 M fruit drink and add 80 ml of water to get 100 ml of 0.2 M solution.

If an ideal gas at a constant temperature is initially at a pressure of 3.8 atm and is then allowed to expand to a volume of 5.6
BabaBlast [244]

Answer:

The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.If an ideal gas at a constant temperature is initially at a pressure of 3.8 atm and is then allowed to expand to a volume of 5.6 L and a pressure of 2.1 - 18914… ... of 5.6 L and a pressure of 2.1 atm, what is the initial volume of the gas? ... An ideal gas is at a pressure of 1.4 atm and has a volume of 3 L.
