Answer:
The answer to your question is: 55.84 u. The element is Iron
Explanation:
isotope 1 mass 53.94 u abundance 5.85%
2 mass 55.9349 abundance 91.75%
3 mass 56.9354 abundance 2.12%
4 mass 57.9333 abundance 0.28%
average atomic mass = (53.94 x 0.0585) + (55.9349 x 0.9175) + (56.9354 x 0.0212) + (57.9333 x 0.0028)
average atomic mass = 3.155 + 51.32 + 1.207 + 0.1622
average atomic mass = 55.84 u. The element is Iron
True. NH4CL is an ionic compound, and salts are strong electrolytes.

Explanation:
Renewable energy sources refers to those energy sources that can never be depleted. This means that they can be used severally without getting exhausted. Solar, biomass, wind and hydroelectric power are all renewable energy sources.
Hence, from the perspective described above, we can say that wind is a form of solar energy because wind is formed when the air is heated by the sun.
Hydroelectric power is driven by the water cycle. This water cycle somehow depends on the sun to run efficiently. So, hydroelectric power can also be considered to be a form of solar energy.
Answer:
374 atoms would be present in 22 units of aluminum sulfate.
Explanation:
Formula for Aluminium Sulfate : Al₂(SO₄)₃
Al = 2
S = 1
O = 4
(SO) = 3
∴ Number of atom in one unit is : 2 + (1+4)3 ==> 17
If there are 17 atoms in one unit, therefore;
Number of atoms in 22 units = 17 x 22
= 374 atoms
