When a strong base reacts with an acid what is always produced?

Y_Kistochka [10]

This really depends. When a strong base reacts with a strong acid, a neutralization reaction occurs, making H2O and neutralizing the pH of the substance. However, when a strong base reacts with a normal acid, nothing is always produced, and the solution will be slightly less basic.

Sodium sulfide reacts with hydrochloric acid to produce hydrosulfuric acid and sodium chloride. (you need to write and balance t

VikaD [51]

Answer:

2.5 moles of NaCl

Explanation:

The balanced chemical reaction equation is shown in the image. Since it takes 2 moles of Hydrochloric acid to form two moles of sodium. Chloride, then 2.5 moles of hydrochloric acid should also form 2.5 moles of sodium chloride according to the balanced reaction equation.

If water and hydrogen peroxide both consist of hydrogen and oxygen atoms, explain why they have different chemical and physical

lana [24]

Water and hydrogen peroxide are different compounds although they have the same kind of atoms. The molecular formula of water is H2O (two atoms of oxygen chemically bonded to one atom of oxygen). The molecular formula of hydrogen peroxide is H2O2, (each atom of oxygen is chemical bonded to one atom of H and other atom of O). So,<span> the presence of different chemical bonds leads to different products with different chemical properties.</span><span />
