Answer:
fruits, vegetables, bread, pasta, and rice
Explanation:
If you play basketball every day so you have to take carbohydrate rich food such as fruits, vegetables, bread and rice etc. These foods have high amount of carbohydrate which fulfill the needs of the body. Basketball is a tough game which requires more energy so for that reason you should eat healthy and nutritive food in order to maintain your health. You should eat the food from which about 55% of the calories comes from the food having high amount of carbohydrates.
Answer:
The reaction is exothermic as the solution becomes warm.
Explanation:
Hello there!
In this case according to the described reaction between sodium metal and water, we can write up the chemical equation whereas the products turn out to be sodium hydroxide and hydrogen gas:
Moreover, these reactions are known to be highly exothermic, for that reason the solution becomes warm as the reaction releases heat as it goes to completion.
Best regards!

Answer:
ΔH of solution = ΔH₁ + ΔH₂ + ΔH₃
Explanation:
- Assume that the solution is formed via dissolving solute A in the molecules of Solvent B.
<em>The formation of the solution goes through 3 steps:</em>
1- The dissociation of the solute A particles, solute breaks apart the intermolecular forces holding the molecules together. It has ΔH₁ > 0 beause this is an endothermic process.
2- The dissociation of the solvent B particles, solute breaks apart the intermolecular forces holding the molecules together. It has ΔH₂ > 0 because this is an endothermic process.
3- The particles of the solvent and solute are holding together. It has ΔH₃ < 0 because this is an exothermic process.
- The enthalpy of the solution (ΔH of solution) will be equal to the sum of the enthalpy change of the three steps.
- ΔH of solution = ΔH₁ + ΔH₂ + ΔH₃.
