Complete and balance the following chemical equation

What is the balanced chemical equation for h2o?

H2 + O2 = H2O – Chemical Equation Balancer.

What are the 4 steps to balancing a chemical equation?

Step 1: Make a Table. In a chemical equation there are subscripts and coefficients. Step 2: Determining and Balancing the First Element. Pick an element that appears in one molecule on the left side and in one molecule on the left. Step 3: Balancing Hydrogen. Step 4: Balancing Oxygen.

Why is it important to balance a chemical equation?

A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed.

What does a complete chemical equation represent?

A chemical equation represents the chemical reaction in a symbolic form. It represents the result of a chemical change.

What is the balanced chemical equation of water?

The following equation describes the burning of hydrogen gas to form liquid water. 2H2(g) + O2(g) → 2H2O(l ) Chemical equations give the following information about chemical reactions. Chemical equations show the formulas for the substances that take part in the reaction.

What type of reaction is h2o?

Water can also undergo a chemical change. Water molecules can be broken down into hydrogen and oxygen molecules by a chemical reaction called electrolysis. When an electric current is passed through liquid water (H2O), it changes the water into two gases—hydrogen and oxygen.

Is 2h2 o2 2h20 a balanced equation?

Yes, the equation is balanced. There are the same number of Hydrogen (H) and Oxygen (O) atoms on both sides of the equation.

How do you write a chemical equation?

Writing Chemical EquationsIn a chemical equation, the reactants are written on the left, and the products are written on the right.The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
