In an exothermic reaction, chlorine reacts with 2.0200g of hydrogen to form 72.926g of hydrogen chloride gas. how many grams of
1 answer:
Answer : 70.906 grams of chlorine reacted with hydrogen
Explanation :
Step 1 : Write balanced chemical equation.
The balanced chemical equation for the reaction between hydrogen and chlorine gas is given below.
Step 2 : Find moles of H₂ gas.
The moles of H₂ can be found as
We have 2.0200 g of H₂ and molar mass of H₂ is 2.02 g/mol.
Let us plug in these values to find moles of H₂.
We have 1 mol of H₂.
Step 3 : Find moles of Cl₂ using mole ratio.
The mole ratio of H₂ and Cl₂ is 1 : 1.
The moles of Cl₂ can be calculated as
Step 4 : Find grams of Cl₂.
Molar mass of Cl₂ gas is 70.096 g/mol
Mass of Cl₂ =
We have 70.906 grams of Cl₂

The reduction of a less active metal by a more active one is called metal displacement reactions. For example:
Fe + CuSO4 → FeSO4 + Cu
<h3>What is metal displacement reaction? </h3>Displacement reactions is a reaction which includes a metal and the compound of a other metal. A more reactive metal will push or displace out a less reactive metal from its compound in this displacement reaction. The metal which is less reactive left uncombined after the reaction.
As we know that, electrons are the basis of the chemical reactions. If chemical compound or element A is more easily oxidized than B, then according to the terms of the activity series, the elements which are more easily oxidized can react with more chemicals, since they are able to act as a reducing agents for more chemicals.
Since, Metal ions are positively charged ions as they lose electrons. Some metals give up their electrons more readily than others and become more reactive.
Thus, we concluded that the reduction of a less active metal by a more active one is called metal displacement reactions. For example:
Fe + CuSO4 → FeSO4 + Cu
