Lemur [1.5K]

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.

Explain how to calculate the density of a regular shaped object such as a rectangular box.
belka [17]

The density of a regular shaped object such as a rectangular box is calculated as thus:

The amount of matter is its mass, and the space it takes up is its volume.

So therefore, to calculate the density of an object such as the a regular shaped one like a rectangular box;

Its density = mass / volume.

<h3>Derived quantities</h3>

These are physical quantities which are obtained from fundamental quantities. I'm order words, derived quantities are quantities which are obtained from the combination of of fundamental quantities either by addition, division or multiplication

Some few examples of derived quantities are as follows:

Density

  • Velocity
  • Upthrust
  • Volume
  • Acceleration

So therefore, the density of a regular shaped object such as a rectangular box is calculated as thus:

The amount of matter is its mass, and the space it takes up is its volume.

So therefore, to calculate the density of an object such as the a regular shaped one like a rectangular box;

Its density = mass / volume.
