Answer:
3Fe2O3 + H2 --> 2Fe3O4 + H2O
Answer:
B) microscopic
Explanation:
A scanning tunneling microscope allows imaging of microscopic particles.
<span>A: best time to go fishing at sea</span>
<span>The molecular formula that describes the problem is
2CH3COOH (aq) + Ca(OH)2 (s) ---> Ca(CH3COO)2 (aq) + 2H2O (l)
The net equation is written as follows:
2CH3COOH- (aq) + 2H+ (aq) + Ca(OH)2 (s) ---> Ca2+ (aq) + 2 CH3COO- (aq) + 2H2O (l)
canceling out spectator ions
2H+ (aq) + Ca(OH)2 (s) ---> Ca2+ (aq) + 2 H2O (l)</span>
I believe it’s B I apologize if it’s wrong
