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:
the density of metal is 7.33 g/cm³.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Given data:
Volume of bar metal = 4.5 cm³
Mass of bar metal = 33 g
Density = ?
Solution:
d = m/v
d = 33 g/ 4.5 cm³
d = 7.33 g/cm³
Free expansion refers to uninhibited or provoked expansion, i.e. it’s expanding on its own, by itself. The only situation in which this occurs is B, as the gas is allowed to expand by itself. A involves a reaction that forces the expansion, C involves the gas performing work, and D involves thermal expansion.
Hope this helps!
The answer is A. 12.2% BaO
Below is the solution as to how the answer was generated:
Let:
25.8g = mass of solute
212g = mass solution
Equation:
% = (mass of solute / mass solution) x 100
Substitute the given values to the equation:
% = (25.8 / 212) x 100
% = 0.122 x 100
= 12.2%
