If calcium oxide can be present by heating calcium metal in oxygen How much calcium would be needed to make 15.0 g of calcium oxide?
To find out how much calcium is needed to make 15.0 g of calcium oxide (CaO), you have to consider the molar ratio of calcium to calcium oxide. The molar mass of CaO is 56.077 g/mol, and the molar mass of Ca is 40.078 g/mol. This means that for every 1 mol of CaO, you need 1 mol of Ca. Calculate the number of moles of CaO in 15.0 g, then use the molar ratio to find the moles of Ca needed. Finally, convert the moles of Ca to grams to find out how much calcium is needed to make 15.0 g of CaO.

If calcium has 2 valence electrons and sulfur has 6 how many calcium atoms are needed to form a ionic bond with sulfur?
To form an ionic bond, calcium (which has 2 valence electrons) can donate its two electrons to sulfur (which requires 2 additional electrons to complete its valence shell). Therefore, one calcium atom can bond with one sulfur atom to form an ionic compound. Thus, only one calcium atom is needed to form an ionic bond with one sulfur atom.

Is calcium beneficial?
yes..calcium is needed for the bones and teeth.
What acid is needed to make calcium chloride?
To make calcium chloride, hydrochloric acid is needed. Calcium chloride is produced by the reaction between calcium carbonate and hydrochloric acid, resulting in calcium chloride, carbon dioxide, and water.
