The chemical formula for calcium hydroxide is: Calculate the molar mass of calcium hydroxide. Round your answer to decimal places.

Chemical Formula = Ca(OH)₂

Molar Mass = 74.09 g/mol

Explanation:

The chemical formula for calcium hydroxide is: Ca(OH)₂. We can know that because the calcium ion always has a +2 charge, while the hydroxide ion has a -1 charge.

We calculate the molar mass by adding together the atomic masses of each atom that makes the compound (these can be found in a periodic table):

Molar Mass = Atomic Mass Ca + (Atomic Mass O)*2 + (Atomic Mass H)*2

Molar Mass = 40.078 + (15.999)*2 + (1.007)*2

Molar Mass = 74.09 g/mol

since electrons are negative the answer is neagtaive

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
