Explanation:
Electrical energy is produced by power plants.
The Light which comes from the Sun.
Chemical energy that is formed in magma.
Nuclear which is stored in the nucleus of an atom.
Geothermal which comes from solar.
Fuel is an inexhaustible resource.
Potential is the energy of position.
It is a base due to the color change!
Hope this helps!
Mark me brainliest please...
Molecular mass of Mg(OH)2
= Atomic mass of Mg + 2(Atomic mass of O) + 2(Atomic mass of H)
= 24 g/mol + 2(16 g/mol) + 2(1 g/mol )
= 58 g/mol
Molecular mass of Fe2O3
= 2(Atomic mass of Fe) + 3(Atomic mass of O)
= 2(56 g/mol) + 3(16 g/mol)
= 160 g/mol
The answer is D I believe
Answer:
a) increase exponentially.
Explanation:
The vapor pressure is depend only on temperature.
The vapor pressure of liquid does not depend upon amount of liquid. For example whether the liquid is 50 g or 30 g its vapor pressure will remain same according to the temperature.
The temperature and vapor pressure have exponential relationship. As the temperature of liquid increases its vapor pressure also goes to increase. When the temperature of liquid goes to decrease its vapor pressure also decreases.
The change in vapor pressure of substance when temperature changes is given as,
ln P₂/P₁ = ΔH(va)/R (1/T₁ - 1/T₂)
