These are termed as permanent hair colors.
Answer:
=14.8 grams
Explanation:
The remaining amount is normally calculated using the formula:
Remaining mass= 1/2ⁿ × Original mass where n is the number of half-lives.
Therefore, original mass= Remaining mass × 2ⁿ
Remaining mass= 2.2 grams
Number of half lives= 2.75 half lives
Original mass= 2.2g × 2²·⁷⁵
=14.8 grams

Answer:
H2O2 → H2O + 1/2O2
Explanation:
0.0800 mol of H2O2 decomposed into 0.0800 mol of H2O and 0.0400 mol of O2
H2O2 → H2O + 1/2O2 - Descomposition reaction.
