A .compound is the combination of two or more atoms
Answer is: 5,9.
Effusion is leakage of gas
through a small hole. Gases with a lower molecular mass effuse more speedy than gases with a higher molecular mass. R<span>elative rates of effusion is related to the molecular mass.
</span>M(O₂) = 32g/mol.
M(CO₂) = 44g/mol.
t₁ = 5s.
t₂ = ?
t₂/t₁ = √(M(CO₂)/M(O₂)).
t₂ = 1,17·5s = 5,9s.
C = covalent
I = Ionic
(I'm lazy to an extent)
An ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals.
H2 = C
Cl2 = C
O2 = C
HCl = C
LiF = I
NaCl = I
NaF = I
MgF = I
NH3 = C
CH4 = C
CO2 = C
NaP = I
N2 = C
NF3 = C
Answer: It means that the energy is being stored or preserved to be used at a later time.
Your question was a little vague, so if this isn't the answer you were looking for, just let me know and I'll fix it.
Hope this helps! Good luck! :D
