Inside this combination of a quiz and worksheet, you can find out how well you understand the calculation of equivalent weight. Questions focus on the n number of equivalents for an acid, and...
The amount of substances that completely react with each other in the reaction is called equivalent weight in chemistry. While answering the question, what is equivalent weight? you should keep in mind that its definition depends on the two factors; the molar mass and valency factor of the compound.
28 maj 2020 · Formic acid. Its formula has twice as many oxygen atoms as the other two compounds (one each). Therefore, 0.60 mol of formic acid would be equivalent to 1.20 mol of a compound containing a single oxygen atom.
1. Balance each of the following equations. Balancing Equations: Answers to Practice Problems. Balanced equations. (Coefficients equal to one (1) do not need to be shown in your answers). 2 Fe+ 3 Cl2 −−→ 2 FeCl3. 4 Fe+ 3 O2 −−→ 2 Fe2O3. 2 FeBr + 3 3 H2SO4 −−→ 1 Fe2(SO4) + 3. (d) 1 C4H6O3 + 1 H2O −−→ 2 C2H4O2. (e) 1 C2H4 + 3 O2 −−→ 2 CO2 + 2 H2O.
The equivalent weight of an element is the number of parts by mass of that element that reacts with or displaces from a combination, such as 1.008 parts by mass of hydrogen, 8 parts by mass of oxygen, or 35.5 parts by mass of chlorine. Equivalent weight of Al for its oxide formation : 2 A l + 3 2 O 2 → A l 2 O 3.
