Answer:

See explanation

Explanation:

Number of moles = reacting mass/molar mass

Number of moles of CaCl2•2H2O = 1.50 g/147.02 = 0.0102 moles

From the equation;

Na2CO3 + CaCl2•2H2O -> CaCO3 + 2NaCl + 2H2O

We can see is 1:1

1 mole of Na2CO3 reacts with 1 mole of CaCl2•2H2O

x moles of Na2CO3 reacts with 0.0102 moles of CaCl2•2H2O

x = 1 × 0.0102 moles/1

x = 0.0102 moles of Na2CO3

Mass of Na2CO3 = 0.0102 moles of Na2CO3 × 106g/mol = 1.08 g of Na2CO3

Signal Words: Assigned to a GHS hazard class and category, "Danger" or "Warning" are used to underline hazards and show the relative level of severity of the hazard.

Danger Statements: Typical expressions that are associated with a hazard class and category and that define the hazard's characteristics. On a label, there must be mention of every danger that applies.

Precautionary Statements: A term that describes actions that should be performed to reduce or eliminate negative effects brought on by exposure to or inappropriate storage of a substance.
