In an exothermic reaction, heat can be considered a __________.

2 answers:

7 0

Answer is: product of reaction.
There are two types of reaction: endothermic reaction (chemical reaction that absorbs more energy than it releases) and exothermic reaction (chemical reaction that releases more energy than it absorbs).
According to Le Chatelier's principle when the reaction is exothermic heat is included as a product.

In an exothermic reaction, heat can be considered a product while in an endothermic reaction heat can be considered a reactant.
Exothermic reaction is a chemical reaction that releases energy in form of light or heat to the surroundings. The total energy of the products is less than the total energy of the reactants, thus the change in enthalpy is negative. Endothermic reactions on the other hand are chemical reactions in which heat is absorbed from the surroundings.

What causes this nuclear reaction to occur

IrinaVladis [17]

Answer:

bombarding it with an energetic particle

Explanation: nuclear reaction, a change in the identity or characteristics of an atomic nucleus, induced by bombarding it with an energetic particle. The bombarding particle may be an alpha particle, a gamma-ray photon, a neutron, a proton, or a heavy-ion.

What is amu of 99 % H-1, .2% H-1 and .8% H-3

ankoles [38]

The average atomic mass of your mixture is 1.03 u .

The average atomic mass of H is the weighted average of the atomic masses of its isotopes.

We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its % abundance).

Thus,

0.99 × 1.01 u = 0.998 u

0.002 × 2.01 u = 0.004 u

0.008 × 3.02 u = 0.024 u

TOTAL = 1.03 u

When the amount of oxygen is limited, carbon and oxygen react to form carbon monoxide. How many grams of CO can be formed from 3

Alinara [238K]

61.25 grams of CO can be formed from 35 grams of oxygen.

The molecular mass of oxygen is 16 gmol⁻¹

The molecular mass of carbon monoxide is 28 gmol⁻¹

Explanation:

The molar mass of carbon monoxide is molar mass of C added to that of O;

12 + 16 = 28

= 28g/mol

The molar mass of oxygen is 16 g/mol while that of oxygen gas (O₂) is 32 g/mol

Since the ration oxygen to carbon monoxide is 1: 2 moles, we begin to find out how many moles of carbon monoxide are formed by 35 g of oxygen;

35/32 * 2

= 70/32 moles

Then multiply by the molar mass of carbon monoxide;

70/32 * 28

= 61.25 g
