Freddy mixes a solid chemical with a liquid chemical and generates a chemical reaction. what can be said about any mixture of chemicals he used? the products will be different than the reactants. the products will be the same as the reactants. the products will be solids. the products will be liquids.

Answer : The correct option is, The products will be different than the reactants.

Explanation :

Chemical reaction : During a chemical reaction, two or more reactants are converted to the one or more different products. Or we can sat that a chemical reaction rearrange the component of atoms of reactants to form a different products.

For example : Magnesium react with water to give magnesium hydroxide and hydrogen gas.

The reaction will be,

Hence, the correct option is, The products will be different than the reactants.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
