Question

by giving an example state why word wquation is called the simplest way to write the chemical equation​

Answer 1

Answer:

Explanation:

The chemical reaction 2 H2(g) + O2(g) → 2 H2O(g) would be expressed as:

hydrogen gas + oxygen gas → steam

As a word equation or as "Hydrogen and oxygen react to form water" or "Water is made by reacting hydrogen and oxygen."

While a word equation doesn't ordinarily include numbers or symbols (Example: You wouldn't say "Two H two and one O two makes two H two O", sometimes it is necessary to use a number to indicate the oxidation state of a reactant so that a person writing a chemical equation can do it correctly. This is mostly for the transition metals, which can have multiple oxidation states.

For example, in the reaction between copper and oxygen to form copper oxide, the chemical formula of copper oxide and the number of copper and oxygen atoms involved depends on whether copper(I) or copper(II) participates in the reaction. In this case, it would be fine to say:

copper + oxygen → copper(II) oxide

or

Copper reacts with oxygen to produce copper two oxide.

The (unbalanced) chemical equation for the reaction would start out as:

Cu + O2 → CuO

Balancing the the equation yields:

2Cu + O2 → 2CuO

You would get a different equation and product formula using copper(I):

Cu + O2 → Cu2O

4Cu + O2 → 2Cu2O

More examples of word reactions include:

Chlorine gas reacts with methane and carbon tetrachloride to produce hydrogen chloride.

Adding sodium oxide to water produces sodium hydroxide.

Iodine crystals and chlorine gas react to make solid iron and carbon dioxide gas.

Zinc and lead two nitrate make zinc nitrate and lead metal.

which means: Zn + Pb (NO3)2 → Zn(NO3)2 + Pb
