the way to get this answer would be to find the answer that has less undissolved mass because you have to find the one with higher solubility, which also means the one that can dissolve the most mass.
Answer:
It has 0.82 moles of gas
Explanation:
Given:
The Volume of gas = 30 L
The pressure of the gas = 0.7 atm
Temperature =315 K
To Find:
Number of moles of the gas = ?
Solution:
According to Ideal gas law
PV =nRT
where
P is the pressure
V is the volume
T is the temperature
n is the number of moles
R is the gas law constant
On substituting the given values in the formula, we get
(0.7) (30) = n (0.0817)(315)
21 = n (25.7355)
n = \frac{21}{25.7355}
n= 0.8159
n = 0.82(rounding off)
Answer:Photosynthesis is the process by which plants use the energy of sunlight to make sugar (glucose) from carbon dioxide and water. Respiration is the process by which animals use O2 to get energy from food. So plants take in CO2 from the air and produce O2, and animals take in O2 from the air and produce CO2.

See the answer below
Explanation:
a) Since the pink phenotype is heterozygous, the genotype would be RW.
b) The pink genotype is RW. Hence, a cross between two pink snapdragons will go thus:
RW x RW
RR RW RW WW
<u>Expected genotypes:</u> 1/4 RR, 1/2 RW, 1/4 WW
<u>Expected phenotypes:</u> 1/4 red-flowered plants, 1/2 pink-flowered plant, 1/4 white-flowered plant.
Answer:
consist of array of chlorophyll molecules. *** The absorb energy excited electrons to a higher energy level. ... *** As H+ diffuse through ATP synthase, down their concentration gradient, the enzyme uses the energy of the moving ions to ATP.
