Question

H2 S+O2⇒ S+O2⇒ S+KOH⇒ S+HNO3⇒ H2 S+FeCL3⇒

Answer 1

Ответ:

Объяснение:

H2 S+2O2= SO2+2H2O

S+O2 = SO2

3S + 6KOH = K2SO3 +2 K2S + 3H2O

S+2HNO3= H2SO4+2 NO

2H2 S+FeCL3= 2FeCl2+S+2HCL

Answer 2

Balancing the Chemical Equation

The given chemical equation is:

H2 + S + O2 → S + O2 → S + KOH → S + HNO3 → H2 + S + FeCl3

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Let's balance the equation step by step:

Step 1: Balancing the hydrogen (H) atoms: - On the left side, we have 2 hydrogen atoms from H2. - On the right side, we have 2 hydrogen atoms from H2 and 1 hydrogen atom from HNO3. - To balance the hydrogen atoms, we need to add a coefficient of 2 in front of HNO3.

The equation becomes:

H2 + S + O2 → S + O2 → S + KOH → S + 2HNO3 → H2 + S + FeCl3

Step 2: Balancing the oxygen (O) atoms: - On the left side, we have 2 oxygen atoms from O2. - On the right side, we have 2 oxygen atoms from O2 and 3 oxygen atoms from HNO3. - To balance the oxygen atoms, we need to add a coefficient of 3/2 in front of HNO3.

The equation becomes:

H2 + S + O2 → S + O2 → S + KOH → S + (3/2)HNO3 → H2 + S + FeCl3

Step 3: Balancing the sulfur (S) atoms: - On the left side, we have 1 sulfur atom from S. - On the right side, we have 1 sulfur atom from S. - The sulfur atoms are already balanced.

The equation becomes:

H2 + S + O2 → S + O2 → S + KOH → S + (3/2)HNO3 → H2 + S + FeCl3

Step 4: Balancing the potassium (K) atoms: - On the left side, we have 0 potassium atoms. - On the right side, we have 1 potassium atom from KOH. - To balance the potassium atoms, we need to add a coefficient of 2 in front of KOH.

The equation becomes:

H2 + S + O2 → S + O2 → 2S + 2KOH → S + (3/2)HNO3 → H2 + S + FeCl3

Step 5: Balancing the iron (Fe) atoms: - On the left side, we have 0 iron atoms. - On the right side, we have 1 iron atom from FeCl3. - To balance the iron atoms, we need to add a coefficient of 1 in front of FeCl3.

The final balanced equation is:

H2 + S + O2 → S + O2 → 2S + 2KOH → S + (3/2)HNO3 → H2 + S + FeCl3

Note: The equation is now balanced, with equal numbers of atoms on both sides for each element.
