The statement that is true regarding the atom that has a charge of +1 in its nucleus for it to have no net charge is that there is one negatively charged electron outside the nucleus (option B).
<h3>How is net charge formed?</h3>
An atom is made up of three subatomic particles namely;
- Proton; which is the positively charged particle
- Electron; which is the negatively charged particle
- Neutron
The number of protons and electrons in the atom is responsible for the net charge of that atom. For example, if there are more protons than electrons, the atom will be positively charged.
However, according to this question, an atom has a charge of +1 in its nucleus. This means that for this atom to have no net charge i.e. 0, there must also be one electron orbiting outside the nucleus.
Therefore, the statement that is true regarding the atom that has a charge of +1 in its nucleus for it to have no net charge is that there is one negatively charged electron outside the nucleus.

Answer:
6782 has 4, 26.2 has 3, 0.3491 has 4 and 55 has 2 significant figures .
Answer:
12
Explanation:
You will need a chemical equation with masses and molar masses, so let’s gather all the information in one place.
: 258.21 18.02
KAl(SO₄)₂·xH₂O ⟶ KAl(SO₄)₂ + xH₂O
Mass/g: 4.74 2.16
Step 1. Calculate the mass of the KAl(SO₄)₂.
Mass = 4.74 g – 2.16 g = 2.58 g.
Step 2. Calculate the moles of each product.
Step 3. Calculate the molar ratio of the two products.
1 mol of KAl(SO₄)₂ combines with 12 mol H₂O, so x = 12.
