Answer:
2.5 moles of O₂ = 5 moles of H₂O
Explanation:
The balanced equation for the reaction is given below:
2H₂ + O₂ —> 2H₂O
From the balanced equation above,
1 mole of O₂ reacted to produce 2 moles of H₂O.
Finally, we shall determine the number of mole of H₂O produced by the reaction of 2.5 moles of O₂. This can be obtained as follow:
From the balanced equation above,
1 mole of O₂ reacted to produce 2 moles of H₂O.
Therefore, 2.5 moles of O₂ will react to produce = 2.5 × 2 = 5 moles of H₂O.
Thus,
2.5 moles of O₂ = 5 moles of H₂O
Answer:
C mechanical potential to chemical to mechanical kinetic
Explanation:
When the cheetah observes it prey, it does not move at all and remains still in one place. This is potential energy.
To chase after its prey or to pounce on it, the cheetah would require energy. This is obtained by its body by performing certain chemical activities that generate energy that help it to move.
When the cheetah finally undergoes this, it has enough energy to finally come out of hiding and chase its prey. This is kinetic energy as while doing so, the cheetah is in motion.
Hope it helps.
