<u>Answer:</u> The chemical species formed in a chemical reaction are products.

<u>Explanation:</u>

In a chemical equation, the chemical species are called as reactants or products.

Reactants are defined as the chemical species that react in the reaction and are written on the left side of the reaction arrow.

Products are defined as the chemical species that are produced in the reaction and are written on the right side of the reaction arrow.

<u>For Example:</u>  Formation of water from hydrogen and oxygen gases, the equation follows:

2H_2(g)+O_2(g)\rightarrow 2H_2O(l)

The chemical species H_2\text{ and }O_2 are termed as reactants and H_2O is termed as products.

Hence, the chemical species formed in a chemical reaction are products.

A student touches a freshly baked cake that was taken out of the oven. Which best explains why the cake feels hot? Options: Mole
chubhunter [2.5K]

Answer:

Molecules in the cake are moving faster than molecules in the skin.

Explanation:

When a cake is baked, the energy is absorbed. This is known as an endothermic reaction. When things are hot, it means that the molecules are in motion. When the cake is taken out from the oven, the molecules are continuously moving and absorbing energy. When the student touches the cake, the heat is flown into the student's body. This happens because of the difference in the temperature between the two.

Solve each of the following problems using one or more conver-sion factors:a. A container holds 0.500 qt of liquid. How many mil
svetoff [14.1K]

Answer:

a. 473mL.

b. 79.38kg

c. 24.47lb of fat

d. 42.5g of N.

Explanation:

a. A qt is equal to 946mL. 0.500qt are:

0.500qt * (946mL / 1qt) = 473mL

b. 1lb is equal to 0.4536kg, 175lb are:

175lb *(0.4536kg / 1lb) = 79.38kg

c. The fat in kg of the athlete is:

74kg * 15% = 11.1kg of fat. In pounds:

11.1kg * (1lb / 0.4536kg) = 24.47lb of fat

d. The mass of nitrogen in the fertilizer is:

10.0oz * 15% = 1.5oz of N

1 oz is equal to 28.35g. 1.5oz are:

1.5oz * (28.35g / 1oz) = 42.5g of N

How many moles of hydrochloric acid are required to produce .40 moles of hydrogen gas?
mash [69]

Answer:

0.80 Moles of Hydrochloric Acid would be required to produce 0.40 Moles of hydrogen gas due to the equation ratios

Explanation:

How many moles of hydrochloric acid are required to produce .40 moles of hydrogen gas?

Hydrochloric acid = HCl

Hydrogen gas = H2

H = 1+

Cl = 1-

HCL = H2 + Cl2

2HCl = H2 + Cl2

2:1:1

0.80 = 0.40 + 0.40
