What is the mass of 0.50 moles of calcium chloride)?

55.5 g

Explanation:

mass = number of moles × molar mass

= 0.50 moles × 110.98 g/mol

= 55.5 g

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.
