There are 2.74266105043 molecules in 100 grams of HCL.
A. the density stays the same unless given an external catalyst
Answer:
HF has the higher boiling point because HF molecules are more polar. Part B: CHBr3 molecules possess stronger intermolecular interaction due to higher molar mass than CHCl3
Explanation:
Fluorine is more electronegative than chlorine. This implies that HF is more polar and possess stronger hydrogen bonds than HCl molecules.
In part B, the magnitude of dispersion forces depend on molar mass, the greater the molar mass, the greater the magnitude of dispersion forces between molecules, hence CHBr3 has a greater boiling point than CHCl3
1 is chemical energy cause thats what gas and electric stoves are
2 is convection
3 is c
Question 4 is C. 13 I believe
