Question

Uh here’s the 20 characters

Answer 1

Mass of the product : 6.039 g

Further explanation

The reaction equation is the chemical formula of reagents and product substances

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products

Reaction

Ba(s)+Cl₂(g)⇒BaCl₂(s)

mol Ba(MW=137,327 g/mol) :

`\tt (4)/(137.327)=0.029`

Mass of BaCl₂ :(MW=208,23 g/mol)

`\tt 0.029* 208.23=6.039~g`
