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.
Answer: nothing. It remains undissolved
Explanation: saturated = dissolved as much solute as solvent can contain
Answer:
520 kg
Explanation:
Let's consider the combustion of isooctane.
C₈H₁₈(l) + 12.5 O₂(g) → 8 CO₂(g) + 9 H₂O(l)
We can establish the following relations:
- 1 mL of C₈H₁₈ has a mass of 0.690 g (ρ = 0.690 g/mL).
- The molar mass of C₈H₁₈ is 114.22 g/mol.
- The molar ratio of C₈H₁₈ to O₂ is 1:12.5.
- The mole fraction of O₂ in air is 0.21.
- The molar mass of air is 28.96 g/mol.
50 L of isooctane require the following mass of air.
Answer:
Photosynthesis is considered an endothermic reaction, because during the process of photosynthesis, energy from the sun or sunlight is being absorbed.
Explanation:
Any chemical reactions that absorb heat energy from the surroundings to form products is termed the endothermic reaction.
