Answer:
Explanation:
2NaNO₃ = 2NaNO₂ + O₂
NaNO₃ = NaNO₂ + 1/2 O₂
- 468 kJ -369 kJ 0 kJ
enthalpy of decomposition reaction
= - 369 - ( - 468 ) kJ
= 99 kJ / mol .
Answer:You can reduce our carbon footprints by using renewable energy,
Explanation:
Answer:
Explanation:
A renewable resource is a resource which can be used repeatedly and replaced naturally. Renewable energy almost never runs out, for example: solar energy is powered by heat from the sun and never runs out. Examples include oxygen, fresh water, solar energy and biomass.
Answer:
kinetic energy
Explanation:
First you have to know the difference between potential and kinetic energy
POTENTIAL ENGRGY: energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
kinetic energy: energy which a body possesses by virtue of being in motion.
An easy way to say it is kinetic energy is the energy of motion.

Answer is: 12 <span>moles of water will be produced.
</span>Balanced chemical reaction: N₂H₄ + O₂ → N₂ + 2H₂O.
n(N₂H₄) = 6 mol.
From balanced chemical reaction: n(N₂H₄) : n(H₂O) = 1 : 2.
n(H₂O) = 2 · n(N₂H₄).
n(H₂O) = 2 · 6 mol.
n(H₂O) = 12 mol.
n - amount of substance.
