The true statement is that after reaching equilibrium, the rate of forming products and reactants is the same.
<h3>What is true about the given reaction?</h3>
The given reaction shows a reaction between A and B to form CD
The reaction is a reversible reaction.
A reversible reaction is a reaction which can proceed in either of two ways where the reactants can react to form the product and also the products an break down to form the reactants.
In the reaction given, as the concentration of A and b decreases, the concentration of CD increases and vice versa.
At equilibrium, the rate of formation of CD is equal to the the rate of decomposition of CD.
Therefore, the true statement is that after reaching equilibrium, the rate of forming products and reactants is the same.
In conclusion, a reaction at equilibrium has the forward and backward reactions occurring at the sane rate.

Answer:
option 3
Explanation:
Neon is one of the noble gases. Noble gases don't react with any element because of their stability. Elements of Group 18 in Periodic Table are inert gases.
Answer:
<h2>The answer is option A</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of object = 7 cm³
density = 5 g/cm³
The mass of the object is
mass = 5 × 7
We have the final answer as
<h2>35 g</h2>

Answer:
C
Explanation:
They are stabil and full of valence electron.
Answer:
Specific heat capacity
Explanation:
Heat capacity is defined as amount of the heat supplied or absorbed by the given mass of the material so to make a unit change in the material's temperature.
The SI unit is Joule / kelvin (J/K).
It is an extensive property.
While,
<u>Specific heat capacity is the amount of heat absorbed or lost by one gram of mass of the substance to raise it's temperature by 1°C or 1 K
</u>
<u>It is an intensive property. </u>
