In a reaction 4.0g of sodium carbonate were reacted with 10g of hydrochloric acid solution. The product was a mixture of 2.5g of carbon dioxide and 11.5g of sodium chloride solution. Is this data in agreement with the law of conservation of mass?

Text Solution

Verified by Experts

The chemical reaction to product is
`"sodium chloride"+"hydrochloric acid" to "sodium chloride solution"+"carbon dioxide"`
`"Mass of reactants"=(4.0+10.0)=14.0g`
`"Mass of products"=(11.5+2.5)=14.0g`
