Question

Which elements make up the the following compounds?

1. Salt

2. Baking Soda

3. Water

4. Hydrogen Peroxide

Answer 1

Salt is composed of sodium and chlorine. Baking soda is composed of sodium, hydrogen, and carbon. Water is composed of hydrogen and oxygen. Hydrogen peroxide is composed of hydrogen and oxygen.

Step-by-step explanation:

1. Salt: Salt is composed of two elements, sodium (Na) and chlorine (Cl). When sodium reacts with chlorine, they form an ionic compound called sodium chloride (NaCl), which is commonly known as table salt.

2. Baking Soda: Baking soda is composed of three elements: sodium (Na), hydrogen (H), and carbon (C). The chemical formula for baking soda is NaHCO3. When baking soda is heated or reacts with an acid, it produces carbon dioxide gas, water, and a salt.

3. Water: Water is composed of two elements, hydrogen (H) and oxygen (O). Its chemical formula is H2O. Water is a polar molecule, which means it has a slightly positive charge on the hydrogen atoms and a slightly negative charge on the oxygen atom.

4. Hydrogen Peroxide: Hydrogen peroxide is composed of two elements, hydrogen (H) and oxygen (O). Its chemical formula is H2O2. Hydrogen peroxide is a pale blue liquid that decomposes easily, releasing oxygen gas.

Answer 2

The element of salt is sodium. The elements of baking soda also called sodium bicarbonate are carbon,sodium,hydrogen and oxygen. The element of water is hydrogen and oxygen. The elements of hydrogen peroxide are hydrogen and oxygen same as water. Hope this helped!!
