A diatomic molecule has a valency of two(2) for a non metal it ,will be negatively charged whereas for a metal, it will be positively charged
I think it would be adaptation and natural selection because both the terms are when an animal adapts to their environment. I hope this helps!
Answer:
The claim is: Therefore Mitosis requires less energy than sexual reproduction does.
Explanation:
The number of moles of the water that was evaporated is 12083467.5 moles of water.
<h3>What moles of water is evaporated?</h3>
We know that the number of moles that we have can be gotten as the ratio of the mass to the number of moles of the object. Now we know that from the question, we have the volume of the hydrogen to be 90,000 gallons. We have to convert this volume to liters.
Given that;
1 gallon = 3.79 L
90,000 gallons = 90,000 gallons * 3.79 L/1 gallon
= 341100 L
Then we have the density of the hydrogen to be 70.85 g/L
Mass of the hydrogen = 70.85 g/L * 341100 L
= 24166935 g
Number of moles of the hydrogen reacted = 24166935 g/2 g/mol
= 12083467.5 moles
If 2 mole of hydrogen gives 2 moles of water
12083467.5 moles of hydrogen gives 12083467.5 moles of water

<span>To solve this we assume that the gas inside the balloon is an ideal </span>gas. Then, we can use the ideal gas equation which is
expressed as PV = nRT. At a constant volume pressure and number of moles of the gas
the ratio of T and P is equal to some constant. At another set of condition, the constant is still the same. Calculations are as follows:
T1/P1 = T2/P2
P2 = T2 x P1 / T1
P2 = 25 x 29.4 / 75
P2 = 9.8 kPa
