Ice because the molecules have less movement in solids
Answer:
i would say the the first 1
Explanation:
Answer:
The correct answer is 5.0 L
Explanation:
STP are defined as T=273 K and P= 1 atm
By using the ideal gas equation, we can calculate the number of moles (n) of the gas at a volume V=2.5 L:
PV= nRT
⇒n= (PV)/(RT) =(1 atm x 2,5 L)/(0.082 L.atm/K.mol x 273 K)= 0.112 mol
For a sample of argon gas, with the same number of moles (0.112 mol) but twice the temperature (T = 273 K x 2= 546 K):
V= (nRT)/P = (0.112 mol x 0.082 L.atm/K.mol x 546 K)/1 atm = 5.0 L
That is consistent with the fact that when a gas is heated, it expanses. So, if the temperature increases twice, the volume also increases twice.
Answer:
H₂ + CuO → Cu + H₂O
Explanation:
We want to balance the given equation;
H₂ + CuO → Cu(OH)₂ + H₂O
To balance this we have to make sure the number of each element on the left is equal to the number of each element on the right.
Thus, the correct balanced equation is;
H₂ + CuO → Cu + H₂O
"only one kind of atom" as in only one element, right?
That would be a diatomic molecule.
