Answer:

E

Explanation:

A combination reaction is one in which two elements or two compounds react to give a new single compound

Hence, what we are expecting on the reactant side is only a single product and not a mixture of products

For the first reaction, we had two elements giving a single product

For the second reaction, we had same

For the third, we had same

For the fourth, we had two compounds reacting to give a singe new product

While in the last, we had two different products which means it does not follow the definition of a combination reaction and that makes it our answer

How many atoms of hydrogen are in 0.56 mol of (NH4)2SO4
BabaBlast [244]
<h2>Answer:2.7\times 10^{24} atoms</h2>

Explanation:

The given formula of the compound is (NH_{4})_{2}SO{4}

The formula says

Every mole of (NH_{4})_{2}SO{4} contains 8 moles of atoms of hydrogen.

Given that number of moles of compound is 0.56

So,the number of moles of hydrogen atoms present is 0.56\times 8=4.48

Since each mole has 6.022\times 10^{23} atoms,

4.48 moles has 4.48\times 6.022\times 10^{23}=2.7\times 10^{24} atoms.
