Volume:
2.00 x 11.0 x 11.0 => 242 cm³
mass : 213 g
D = m / V
D = 213 / 242
D = 0.880 g/cm³
Answer B
hope this helps!
Density = Mass ÷ Volume
D= 30g ÷ 6 cm^3
D= 5 g/dm^3
A. True would be the best answer
The formal charge of H = +1, because F in compounds can have only -1.
A catalyst is when a chemical reaction occurs faster than normal.
The system is unaffected during a catalyst because both forward and reverse reactions are affected, meaning that quilibrium will occur faster nothing will change.
