How is stoichiometry used to calculate the amount of product produced

Stoichiometry relates moles of reactant to moles of product, so if you have the amount of reactant in the equation, you can calculate the amount of product produced.

What happens to the anode in an electrochemical cell

it loses mass

Why is the average atomic mass used when calculating grams of a substance

the elements in the substance are mixtures of their isotopes

Which of the following best describes a galvanic cell

A battery containing a spontaneous redox reaction

All life on earth is ultimately dependent on what

The sun for energy

Similar scientific themes are seen in what areas of science

In all areas of science

If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element

The abundance percentage of each isotope

In the reaction MgCI2 plus 2KOH MgOH2 plus 2KCI how many moles of MgOH2 are produced for every mole of MgCl2

The answer is one mole.

In the reaction mgcl2 plus 2koh mgoh2 mgoh2 plus 2kcl if 3 moles mgcl2 are added to 4 moles koh what determined how much mgoh2 is made

The amount of Koh
