Answer : The balanced chemical reaction will be:

2H_2+O_2\rightarrow 2H_2O

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

As per question, when 2 molecules of hydrogen gas and 1 molecule of oxygen gas react to yield 2 molecules of water.

The balanced chemical reaction will be:

2H_2+O_2\rightarrow 2H_2O

2H2+O2→2H2O
We have to be aware that the number of atoms are the same on both reactant side and product side.

Rank the following salts in order of decreasing pH of their 0.1 M aqueous solutions:FeCl₂ , FeCl₃ , MgCl₂ , KClO₂
Natalija [7]

The pH of the salts in decreasing order is FeCl2, FeCl3, MgCl2, KClO2.

What is pH?

pH is an expression of hydrogen ion concentration in water. Specifically, pH is the negative logarithm of hydrogen ion (H+) concentration (mol/L) in an aqueous solution:

pH = -log10(H+)

The term is used to indicate basicity or acidity of a solution on a scale of 0 to 14, with pH 7 being neutral.

As the concentration of H+ ions in solution increases, acidity increases and pH gets lower, below 7. When pH is above 7, the solution is basic.

Because pH is a logarithmic function, one unit change in pH indicates a 10x change in H+ concentration in that solution.

However, what is actually measured is hydrogen ion activity, not concentration.
