How many grams of oxygen are required to burn 10.0 g magnesium? The molar mass of O2 is 32.0 g/mol, and the molar mass of Mg is 24.3 g/mol.
2Mg(s) + O2 → 2MgO(s)

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.

How might this scientific phenomena be explained? a paper clip floats on water.

We are hoping to create 5.72 grams of glucose. the plant was given 4.75 liters of co2 and 2.81 g of h20. which reactant was the limiting reagent? how much excess mass did we have of the other reactant?
