Answer:
Single displacement and reduction
Explanation:
In a single-displacement reaction, one element exchanges partners with another.
This is a single-displacement reaction, because the element Ca exchanges partners with H.
This is also a reduction/oxidation (redox) reaction, because the optically active of Ca increases from 0 to +2 (oxidation), while the oxidation number of H decreases from +1 to 0 (reduction),
The most common types of reactions are:
- Combination
- Decomposition
- Single displacement
- Double displacement
- Reduction/oxidation
Answer : The minimum amount of 6.9 M needed is, 2.0 L
Explanation :
The given chemical reaction is:
First we have to calculate the moles of
Molar mass of = 2 g/mol
Now we have to calculate the moles of
From the balanced chemical reaction we conclude that,
As, 3 moles of produced from 3 moles of
So, 13.9 moles of produced from 13.9 moles of
Now we have to calculate the mass of
Thus, the minimum amount of 6.9 M needed is, 2.0 L
