MgCl₂ & PbSO₄ is the correct product for the given double replacement reaction.
<h3>What is double displacement reaction?</h3>
In the double displacement reaction displacement of two substrate will take place among two reactants and formation of products takes place.
In the question, PbCl₂ reacts with MgSO₄ and displacement between the cations takes place and formation of MgCl₂ and insoluble precipitate PbSO₄ is formed.
Given reaction is represented as:
PbCl₂ + MgSO₄ → MgCl₂ + PbSO₄
According to the activity series, reactivity of Magnesium is more as compared to the lead atom. So lead is displaced by the magnesium atom and form the above given products.
Hence, option (3) is correct i.e. MgCl₂ & PbSO₄.

Answer:
Osmosis is the diffusion of ⇒ water across a selectively permeable membrane. This process does not require the cell to use ⇒ energy to move molecules. It is an example of ⇒ passive transport.
Explanation:
The answer for the first question would be water. It is the substance that is a compound since it is made up of different elements. For the second item, i think the best answer is phosphorus and nitrogen. They are the limiting nutrients. For the last item, the correct answer is reservoirs.
Answer:
D
Explanation:
Process of elimination. There is more than just water vapor in a vape so it can't be D, it isn't a cigarette so it can't be B, and A is just clearly not the answer haha.
Answer:anions with least precipitates are anions of salt produce by a strong acid and strong base e.g KCL,Na2SO4,
Explanation: salts produce from strong acid such as HCL and a strong base such as KOH are extremely soluble and hence produce little or no precipitate when dissolved in water .meaning the salt are highly soluble , most group1 elements form salts that are highly soluble and hardly precipitates e.g Na(sodium) pottasium(K) ,lithium(Li)salts.they are called alkaline metals.
B) exception to the rules are hydrogen and Rubidium.hydrogen because it occurs basically as a gas and forms H^+ which tend to form a hydrogen bond while rubidium is a heavy metal forming insoluble salt
