The Law of Modern periodic tabel was given by___________

1. A Mendeleev
2. B Mosley
3. C Lavoisier
4. D Newton

Correct Answer :  B

According to Moseley "The properties of elements and their compounds are periodic functions of their increasing atomic numbers". He arranged elements in periodic table in increasing order of their atomic numbers. It was found successful due to number of reasons and the most important was the position of isotopes as they are nuclei with same atomic numbers so they were placed under the same elements to which they belong. This law also led to the discovery of many new elements.

Which of the following gas is the most toxic?

1. A CO₂
2. B SO₂
3. C CO
4. D CH₄

Correct Answer :  C

Carbon monoxide (CO) is a poisonous, colorless, odorless and tasteless gas.

Why is CO so harmful?
Carbon monoxide is harmful when breathed because it binds very strongly to the iron in hemoglobin. Once carbon monoxide attaches, it is very difficult to release. So if you breath in carbon monoxide, it sticks to your hemoglobin and takes up all of the oxygen binding sites. Eventually, blood loses all of its ability to transport oxygen, and you suffocate.
