Question

For each of the reactions below give a balanced equation.

1)Methane (CH4) with chlorine to give chloroform (CHCL3)and hydrogen cloride.

2) Sodium Hydroxide with phosphoric acid.

3)sodium carbonate with sulfuric acid.

4) sodium sulfide with hydrochloric acid.

Answer 1

simple google searches reveal:

1)
CH₄ + Cl₂ = CH₃Cl + HCl

2)
H₃PO₄ + 3NaOH = Na₃PO₄ + 3H₂O

3)
Na₂CO₃ + H₂SO₄ -> Na₂SO₄ + H₂O + CO₂

4)
Na₂S + 2HCl = H₂S + 2NaCl

Answer 2

Thank you so much!!!!

Answer 3

THANK YOU SOOOOO MUCH!!!!!!

Answer 4

Sure! I can help you with that. To balance chemical equations, follow these steps:

1) Start by writing the unbalanced equation with the correct chemical formulas for each reactant and product.
2) Count the number of atoms for each element on both sides of the equation.
3) Adjust coefficients in front of each compound or element to balance the equation.
4) Double-check that the equation is balanced by counting the atoms again.

Let's apply these steps to balance the equations you provided:

1) Methane (CH4) with chlorine to give chloroform (CHCl3) and hydrogen chloride (HCl):

Unbalanced equation: CH4 + Cl2 → CHCl3 + HCl

To balance the equation:
CH4 + Cl2 → CHCl3 + 3HCl

Now, let's count the atoms:
Carbon: 1 on both sides
Hydrogen: 4 on both sides
Chlorine: 2 on both sides

The equation is balanced.

2) Sodium hydroxide (NaOH) with phosphoric acid (H3PO4):

Unbalanced equation: NaOH + H3PO4 → Na3PO4 + H2O

To balance the equation:
3NaOH + H3PO4 → Na3PO4 + 3H2O

Now, let's count the atoms:
Sodium: 1 on both sides
Hydrogen: 4 on both sides
Oxygen: 5 on both sides
Phosphorus: 1 on both sides

The equation is balanced.

3) Sodium carbonate (Na2CO3) with sulfuric acid (H2SO4):

Unbalanced equation: Na2CO3 + H2SO4 → Na2SO4 + CO2 + H2O

To balance the equation:
Na2CO3 + H2SO4 → Na2SO4 + CO2 + H2O

Now, let's count the atoms:
Sodium: 2 on both sides
Carbon: 1 on both sides
Oxygen: 7 on both sides
Hydrogen: 4 on both sides
Sulfur: 1 on both sides

The equation is balanced.

4) Sodium sulfide (Na2S) with hydrochloric acid (HCl):

Unbalanced equation: Na2S + HCl → NaCl + H2S

To balance the equation:
Na2S + 2HCl → 2NaCl + H2S

Now, let's count the atoms:
Sodium: 2 on both sides
Sulfur: 1 on both sides
Chlorine: 2 on both sides
Hydrogen: 2 on both sides

The equation is balanced.

I hope this helps! Let me know if you have any further questions.
