One swimmer can cover 100 meters in 30 seconds.
- Answer:
Energy release is exothermic reaction whiles energy absorb is endothermic reaction
Explanation:
Exothermic reaction is when the reactant is above the product while endothermic the product is below the reactant in the diagrams we have some part as activation energy
The chloroplasts convert radiant energy into chemical energy. Mitochondria convert food into energy.
Mitochondria = Animal Cell ONLY
Chloroplasts = Plant Cell ONLY
Hope this helps you! :)
1) Answer is: WO3 + 3H2 → W + 3H2O.
Reduction reaction: W⁺⁶ + 6e⁻ → W⁰.
Oxidation reaction: H₂ → 2H⁺¹ + 2e⁻ / ×3; 3H₂ → 6H⁺¹ + 6e⁻.
Wolfram change oxidation number from +6 to 0 (reduction) and hydrogen change oxidation number from 0 to 01 (oxidation).
In other examples, elements do not change their oxidation numbers.
2) Answer is: It increases the average kinetic energy and there are more collision per minute.
The collision theory states that a certain fraction of the collisions (successful collisions) cause significant chemical change.
The successful collisions must have enough energy (activation energy).
Chemical bonds are broken and new bonds are formed.
Particles are in constant, random motion and possess kinetic energy, molecules faster and have more collisions.
Answer:
