A natural charge by an atom is caused by which of the following conditions?
Lera25 [3.4K]

Answer:

C

Explanation:

I'm assuming that you meant to type neutral charge.

Since electrons are negative and protons are positive, having a balanced number of both of these would cause an atom to have a neutral charge.

Describe why the overgrowth of algae in eutrophication is a bad thing.
Tanya [424]

Answer:

The overgrowth of algae consumes oxygen and blocks sunlight from underwater plants. When the algae eventually dies, the oxygen in the water is consumed. The lack of oxygen makes it impossible for aquatic life to survive

Explanation:

hope this helps have a good rest of your afternoon :) ❤

Write the empirical formula of at least four binary ionic compounds that could be formed from the following ions:
Elan Coil [88]

Answer:

MgI₂, MgO, PbI₄, PbO₂

Explanation:

For an ionic compound to be formed, it must be neutral, that is the total positive charge must be equal to the total negative charge.

Mg²⁺ and I⁻: The neutral ionic compound requires 1 Mg²⁺ and 2 I⁻ and the resulting empirical formula is MgI₂.

Mg²⁺ and O²⁻: The neutral ionic compound requires 1 Mg²⁺ and 1 O²⁻ and the resulting empirical formula is MgO.

Pb⁴⁺ and I⁻: The neutral ionic compound requires 1 Pb⁴⁺ and 4 I⁻ and the resulting empirical formula is PbI₄.

Pb⁴⁺ and O²⁻: The neutral ionic compound requires 1 Pb⁴⁺ and 2 O²⁻ and the resulting empirical formula is PbO₂.

Use the following MO diagram for Be2, Be2+, and Be2-. Based on this diagram,
Marta_Voda [28]
Bond Order = [Σ (bonding e-) - Σ (antibonding e-)]/2 
<span>Be2 = 4e = σ1(2e) σ2*(2e) σ3(0) π1(0) π2*(0) σ4*(0) bo = 0 </span>
<span>[Be2]+ = 3e = σ1(2e) σ2*(1e) σ3(0) π1(0) π2*(0) σ4*(0) bo = 0.5 </span>
<span>[Be2]+ would be more likely to exist since it has a bond order of 0.5 whereas Be2 has zero bond order</span>
