Answer:

a chemical equation

Explanation:

Chemical equation is a representation of chemical reaction in terms of chemical formulas and symbols . The chemical equation has two sides namely the Reactant and the Product . The reactant is the substance combined or reacted to form another. The product is the result or substance gotten after the reaction between the reactant.

A chemical equation must be balanced . The number of atom on both sides (reactant and product) must be the same. Sub-scripted numbers are use to represent the number of actual atom present in the substance. Example H2O . The bold value, 2 is a sub-scripted number and it indicate that hydrogen has two atom in the chemical formula.

Example of chemical equations includes

2Mg + 02 → 2MgO

2H2 + O2 → 2H2O

Hcl + NaOH → Nacl + H2O

Notice the number in front of the chemical formula of the substance, it is used to balance the number of atom on both sides of the equation. The number is called coefficients.

Stochiometry .How many grams of CO2 is produced when excess CS2 reacts with 4 mols of O2? CS2+O2-SO2 Please balance equation.
Travka [436]

Mass of CO₂ produced : 58.67 g

<h3>Further explanation</h3>

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

CS₂ + 3O₂  -------> CO₂ + 2SO₂

mol of CO₂ based on mol of O₂ as a limiting reactant(CS₂ as an excess reactant)

From the equation, mol ratio of mol CO₂ : mol O₂ = 1 : 3, so mol CO₂  :

\tt \dfrac{1}{3}\times 4=\dfrac{4}{3}

mass  CO₂ (MW= 44 g/mol) :

\tt \dfrac{4}{3}\times 44=58.67~g
