What is the classification of the reaction shown in the equation below? Fe + O2 → FeO2
A
decomposition
B
double replacement
C
single replacement
D
synthesis

d

Explanation:

because is a reducing agent, O 2 is an oxidizing agent.

gas and liquid

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
