Answer:
Potential energy plus kinetic energy equals mechanical energy because mechanical energy is basically just all of an object's energy, it's just two kinds of energy. The potential is stored inside and kinetic is being used. Both of those together is the total amount of the objects energy, which is the mechanical energy.
Explanation:
1 g = 1 ÷ 1000 kg
= 0.001 kg
1 cm³ = 1 ÷ 100 ÷ 100 ÷ 100 m³
= 0.000001 m³
1 g/cm³ = 1 g / 1 cm³
= 0.001 kg / 0.000001 m³
= 1000 kg/m³
The density is 1000 kg/m³.
If the pressure above a solution containing a gas solute is reduced, the limit of the gas's solubility will decrease.
Answer:
2 electrons will be needed by unbound oxygen in order to fill its 2nd shell.
Explanation:
The chemical reaction between magnesium and oxygen gives magnesium oxide as a product.The reaction is chemically represented as:
Magnesium is a metal of group-2 with 2 valence electrons.It has atomic number of 12.
In order to attain noble gas configuration it will loose two electrons.
...[1]
Oxygen is a non metal of group-16 with 6 valence electrons..It has atomic number of 8.
In order to attain noble gas configuration it will gain two electrons.
..[2]
2 electrons will be needed by unbound oxygen in order to fill its 2nd shell.
