Answer:
O ice melts at 0°C that is the answer
Answer: Physical change
Explanation: Condensation is the phase change of a gas to the liquid state. There is no formation of new products so it does not undergoes chemical change. Any phase change is considered a physical change.
Answer:
The answer is "Choice A and Choice B"
Explanation:
The Zero-Order reactions are usually found if a substrate, like a surface or even a catalyst, is penetrated also by reactants. Its success rate doesn't depend mostly on the amounts of the various reaction in this reaction.
Let the Rate = k
As 
doesn't depend on reaction rate, a higher reaction rate does not intensify the reaction.
By the rate 
the created based and the reaction rate is about the same.
Answer:
The volume is 310 L
Explanation:
We use the ideal gas formula, with the constant R = 0.082 l atm / K mol. The STP conditions are 1 atm pressure and 273 K temperature. Solve for the formula, V (volume):
PV= nRT ---> V= (nRT)/P
V=( 14 mol x 0,082 l atm /K mol x 273 K)/ 1 atm
<em>V= 313,404 L</em>
The answer is the cell wall
