Answer:
B) 5
Explanation:
When an atom lose are gain the electron ions are formed.
There are two types of ions. Cation and anion.
Cation:
It is formed when an atom lose the electrons.
X → X⁺ + e⁻
Anion:
It is formed when an atom gain the electron.
X + e⁻ → X⁻
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.
if an atom has 8 protons it means there were eight electrons present. when it lost three electron it have +3 charge and number of electron that remain are five. 8-3 = 5
Answer:
Potential Energy
Explanation:
Right now, the match is giving off no energy to it's environment.
<em>Light</em><em> </em><em>it</em><em>.</em>
Now it's giving off a few kinds:
- Thermal energy (heat)
- Light energy
The match has the potential to have energy, but it currently has none.
Answer:
1 mole of P₄ consumed:4 moles of PBr₃ produced
Explanation:
Look at the coefficients in the balanced chemical equation to determine the ratios. For every 1 mole of P₄ consumed (P₄ has a coefficient of 1), 4 moles of PBr₃ would be produced (PBr₃ has a coefficient of 4).
