Answer:
10.88 moles of magnesium hydroxide contain 65.52 ×10²³formula units
Explanation:
Given data:
Number of formula units of magnesium hydroxide = ?
Number of moles = 10.88 mol
Solution:
The given problem will be solve by using Avogadro number.
The number 6.022×10²³ is called Avogadro number.
1 mole contain 6.022×10²³ formula units.
10.88 mol × 6.022×10²³formula units /1 mol
65.52 ×10²³formula units
Thus, 10.88 moles of magnesium hydroxide contain 65.52 ×10²³formula units .
Answer:
6 moles of CuCl₂ will produced 4 moles of AlCl₃ .
Explanation:
Given data:
Moles of CuCl₂ = 6 mole
Moles of AlCl₃ produced = ?
Solution:
3CuCl₂ + 2Al → 2AlCl₃ + 3Cu
Now we will compare the moles of CuCl₂ with AlCl₃ .
CuCl₂ : AlCl₃
3 : 2
6 : 2/3 ×6 = 4 mol
So, 6 moles of CuCl₂ will produced 4 moles of AlCl₃ .
The statement that is NOT true of fission is B. slow neutrons are fired at a large nucleus.
<h3>
What is Nuclear fission</h3>
This is the splitting of large nuclei to smaller ones. It could be a natural or spontaneous dissociation by radioactive decay, or can be initiated in in a laboratory under required conditions. It involves;
- Splitting of large nuclei to two smaller ones
- Release of large amount of energy
- Neutrons released can be used to initiate chain reactions
Hence, the statement that is not true about fission is that slow neutrons are fired at a large nucleus.
