0.607mol
Explanation:
n(AR) = mass / molar máss
= 24.3 /40
=0.607
B. Developing theories using many lines of evidence
Answer:
friction
Explanation:
the resistance that one surface or object encounters when moving over another.
When heating lithium carbonate (Li2CO3), it will dissociate to Li2O and Co2. So the balanced chemical equation of this reaction is Li2CO3 = Li2O + CO2.
It is a. oxidation-reduction
