Which ion will most likely form a precipitate when reacted with SO42 ?
Charra [1.4K]
<h2>Answer:Ba^2+</h2>

Explanation:

option A:

SO_{4}^{2-} is an anion and Cl^{1-} is also an anion.So,there is no reaction.

option B:

K^{+} reacts with SO_{4}^{2-} to form K_{2}SO_{4}.

Since K is a first group element,all its salts are soluble in water.

Hence no precipitate is formed.

option C:

Na^{+} reacts with SO_{4}^{2-} to form Na_{2}SO_{4}.

Since Na is a first group element,all its salts are soluble in water.

Hence no precipitate is formed.

option D:

Ba^{2+} reacts with SO_{4}^{2-} to form BaSO_{4}.

Solubility of sulphates of second group elements decrease down the group.

So,BaSO_{4} is a precipitate.

A sample of radioactive material starts with 80 grams. After 3 half-lives have passed, how much radioactive sample remains?
Elanso [62]

Answer:

After 3 half lives 10 g of radio active material left.

Explanation:

Given data:

Total amount of radio active material = 80 g

Amount left after 3 half lives = ?

Solution:

At time zero = 80 g

At first half life = 80 g/2 = 40 g

At 2nd half life = 40 g/2 = 20 g

At 3rd half life = 20 g/2 = 10 g

Thus, after 3 half lives 10 g of radio active material left.
