Magnesium is reacted with an excess of nitric acid, HNO3 8.32 grams of hydrogen gas should theoretically be produced. What is the percent yield if only 7.26 grams of hydrogen gas is collected

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.

What is the mass of naoh that would have to be added to 500 ml of a solution of 0.20 m acetic acid in order to achieve a ph of 5.0?

How do you determine the percent yield of a chemical reaction
