Goshia [24]

Answer: it started too rot over time mold over time and decay and if you cooked a apple it would melt like ice cream cause of the heat waves and if the apple is surrounded by air i think what would happen it would still rot I guess but i wouldnt know for sure cause things with air take time too rot and things with air rot faster and slicing the apple into more pieces would make it decay or rot or mold faster cause its open and accepting everything it sees like bacteria bugs all that

Explanation: like the longer a apple is left half open it starts too rot then mold over time getting all bad and not good too eat or decay

read it all the stuff is in there i think

Carbon and oxygen combine to form carbon dioxide. What are the products, or what
Vladimir [108]
<h3>Answer:</h3>

Carbon dioxide

<h3>Explanation:</h3>
  • During chemical reactions elements or compounds that combine to form other new compounds are known as reactants
  • The newly formed compounds or molecules after a reaction has taken place are known as products.

In this case;

  • The chemical reaction between carbon and oxygen results to the formation of carbon dioxide.
  • The equation for the reaction is; C + O₂ → CO₂
  • Therefore, carbon and oxygen are the reactants while carbon dioxide is the product.

How much heat is absorbed during production of 147 g of NO by the combination of nitrogen and oxygen?
marin [14]

Answer:

\large \boxed{\text{105 kcal}}

Explanation:

MM:                        30.01

            N₂ + O₂ ⟶ 2NO; ΔH = +43 kcal/mol

m/g:                         147

Treat the heat as if it were a reactant in the reaction. Then you can write

N₂ + O₂ + 43 kcal ⟶ 2NO

The conversion factor is then 43 kcal/2 mol NO.

1. Moles of NO

\text{Moles of NO} = \text{147 g NO} \times \dfrac{\text{1 mol NO}}{\text{30.01 g NO}} = \text{4.898 mol NO}

2. Amount of heat

\text{Heat} = \text{4.898 mol NO } \times \dfrac{\text{43 kcal}}{\text{2 mol NO}} = \text{105 kcal}\\\\\text{The reaction absorbs $\large \boxed{\textbf{105 kcal}}$}

Which of the following will affect the rate of a chemical reaction?
max2010maxim [7]

Answer:

solution concentration

Explanation:

Among the options given in the above question, solution concentration will affect the rate of a chemical reaction. This is because an increase in reagent concentration speeds up the reaction because there will be a greater number of reagent particles per unit volume, increasing the likelihood of effective collisions between them.

In addition to concentration, the factors that can influence the rate of a chemical reaction are temperature, catalyst, pressure and contact surface.
