When the following molecular equation is balanced using the smallest possible integer coefficients, the values of these coeffici
tatuchka [14]

The values of the coefficients would be 4, 5, 4, and 6 respectively.

<h3>Balancing chemical equations</h3>

The equation of the reaction can be represented by the following chemical equation:

ammonia (g) + oxygen (g) ---> nitrogen monoxide (g) + water (g)

  4NH_3(g)     +    5O_2(g)        --->           4NO(g)              +  6H_2O(g)

Thus, the coefficient of ammonia will be 4, that of oxygen will be 5, that of nitrogen monoxide will be 4, and that of water will be 6.

The process of fermentation involves chemical reactions that convert solid glucose (C6H12O6) into aqueous ethanol and carbon dio
Sidana [21]

Explanation:

The glucose molecules changes as following:

C6H12O6 —> C2H5OH + CO2

There are 12 atoms of H on the left side and 6 atoms of the right side. It can be balance by putting 2 in front of C2H5OH as shown below:

C6H12O6 —> 2C2H5OH + CO2

There are 6 atoms of C on the left side and 5 atoms on the right side. It can be balance by putting 2 in front of CO2 as shown below:

C6H12O6 —> 2C2H5OH + 2CO2

The solubility of oxygen in water A. allows for a greater concentration of O2 in water than in air. B. is responsible for thermo
Vanyuwa [196]

The ans should be C. ( if i'm not wrong )

This is because the solubility of oxygen increases when temperature in the water is cooler. Cold water can hold more dissolved oxygen than warm water, thus having a higher concentration of oxygen.

How can the concentration of a solution be changed
Vlad1618 [11]

The mass of the salt converted into moles divided by the liters of water in a solution would give the Molarity (M) or concentration of the solution. The simplest way to change the solution would be to change the amount of solute or solvent in a solution.
