_____ Na3PO4 + _____ KOH arrow _____ NaOH + ___________K3PO4
How do I balance this equation?
Answer:
It is an exothermic reaction.
Explanation:
Why? Since the kJ is added to the product side, we know that this is an exothermic reaction since it is releasing heat. Endothermic reactions absorb heat and thus it would be represented on the products side.
To represent this exothermic reaction we would draw a curve starting mid graph then it goes up and then dropsdown. In other words, it looks downhill since it's releasing heat wheras an edothermic rxn, it is gaining heat, thus it looks like it is going upwards.
Plants need energy for Reproduction, Photosynthesis, Growth, and Development amongst others.
To produce their own food energy, which is referred to as "photosynthesis," plants need water and sunlight. They need energy because they are living things.
Photosynthesis is the process by which plants turn solar energy into sugar. Light energy is utilized by photosynthesis to transform carbon dioxide and water.
Numerous biological functions, such as growth and reproduction, require energy. Therefore, energy is absolutely essential.

Answer:
Condensation and vaporization
Explanation:
At a given temperature, molecules of a liquid move into the gas phase (vaporization) and the molecules of the vapour can move back into the liquid phase (condensation).
