Question

balance the following equation stepwise​

Answer 1

Answer:

Explanation:

Ans 1) Step1: Count the number of atoms in reactant side:

H=4

0=8

S=2

Step2: Count the number of atoms in product side:

H=2

S=1

O=4

Step3: Then balance the numbe rof atoms on both sides by multiplying reactant and product with numerical values:

If we multiply the product side by 2, we can clearly see that number of atoms present in reactant side is equal to number of atoms present in product side as shown below:

H2S207 + h20 gives 2[H2SO4]

Ans 2) Balanced equation is:

SO2+2H2S gives 3S+2(H2O)

Ans 3) Balanced equation is:

2Ag+2HCl gives 2AgCl+H2

Ans 4) Balanced equation:

2NaOH+H2SO4 gives Na2SO4+2H2O
