A solution with a pH of 7 is

Explanation
A solution with a pH of 7 is water because water has a neutral pH of 7. A pH of 7 indicates that the solution is neither acidic nor basic, but rather it is balanced. Water molecules dissociate into equal numbers of hydrogen ions (H+) and hydroxide ions (OH-), resulting in a neutral pH. Therefore, a solution with a pH of 7 can be identified as water.

9.

Rust is a product of

Explanation
Rust is a product of oxidation because it is formed when iron or steel reacts with oxygen in the presence of moisture. This reaction leads to the formation of iron oxide, commonly known as rust. The process of oxidation involves the transfer of electrons from the iron to the oxygen, resulting in the formation of the rust.

Rate this question:

4
10.

An element with 29 electrons is

Explanation
Copper is the correct answer because it has 29 electrons. The atomic number of copper is 29, which indicates the number of protons and electrons in an atom of copper. Since atoms are electrically neutral, the number of electrons is equal to the number of protons. Therefore, an element with 29 electrons is copper.

Rate this question:

4
11.

A substance containing only elements 1 and 8 is

Explanation
Water is a substance that contains only elements 1 and 8, which refers to hydrogen (H) and oxygen (O) respectively. The chemical formula for water is H2O, meaning it consists of two hydrogen atoms bonded to one oxygen atom. Therefore, water is the correct answer for a substance containing only elements 1 and 8.

Rate this question:

An element that can be used as a starch indicator is

Explanation
Iodine can be used as a starch indicator because it reacts with starch to form a dark blue or black color. This reaction occurs due to the formation of an inclusion complex between iodine molecules and the helical structure of amylose, a component of starch. The color change is a result of the absorption of light by the complex. Therefore, when iodine is added to a solution containing starch, the presence of starch can be detected by the formation of a blue or black color.
