Compounds that are gases at room temperature are covalent bonds (nonmetal + nonmetal).
Answer:
Explanation:
It's water vapor. There is enough heat present to get the water to boil but not enough to break it into its chemical components (oxygen and hydrogen), so the answer is D.
Answer/Explanation:
Things that will vary include the distribution of electrons between atoms, lone pairs, and bonds, the number of single vs double or triple bonds, and the formal charges on atoms in the structure.
All resonance forms of the same molecule or ion must have the same number of atoms, connected in the same way, and the same number of total electrons.
Percentage yield= (actual/theoretical)x100
So in this case the actual yield is 110 and the theoretical yield is 125.
So you would do =(110/125)x100
So the answer would be =88%
Answer:
Then pressure will double
Explanation:
PV = nRT
P = nRT / V
If all other variables are kept constant, P will be proportional to n i.e
P1 / n1 = P2 / n2
n = 1
P1 = P
n2 = 2
P2 =?
P1 / n1 = P2 / n2
P /1 = P2/2
Cross multiply
P2 = 2P
Therefore, if an additional 1mole of the gas is added, the pressure will double
