Oxygen and nitrogen are both gases at room temperature. Explain why oxygen has a greater force of attraction between its particl
RideAnS [48]

Answer:

Explanation:

Oxygen molecules and Nitrogen molecules forms in a very similar way. The attraction between particles of oxygen is great due to its very high electronegativity value. Oxygen has a higher electronegative value compared to nitrogen.

Electronegativity of an atom is the relative tendency with which atoms of an element attracts valence electrons in a chemical bond. Valence electrons are used in forming chemical bonds. They can be transferred from one atom to the other or they can be shared.

Oxygen is the second most electronegative atom on the periodic table. To form a bond, it shares the valence electrons in order for its octet to be complete. Pull for the valence electrons between the contributing atoms is very strong due to their large electronegative values. This pull is stronger compared to that between nitrogen atoms.

The percent of remaining parent isotope in a radioactive decay process is 40 percent. How many half-lives have elapsed since the
muminat

Answer: Between 1 and 2.

Explanation:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

a=\frac{a_o}{2^n}        ............(1)

where,

a = amount of reactant left after n-half lives  = 40

a_o = Initial amount of the reactant  = 100

n = number of half lives

Putting in the values we get:

40=\frac{100}{2^n}  

2^n=2.5

taking log on both sides

nlog(2)=log(2.5)

n=1.32

Thus half-lives that have elapsed is between 1 and 2
