Elements in the same group have the same number of outer-shell electrons or "valence" electrons, so they tend to react similarly, as they can form similar bonds.
Answer: Option (e) is the correct answer.
Explanation:
Equilibrium is defined as the state of a chemical reaction in which the rate of forward reaction is equal to the rate of backward reaction.
The state of equilibrium is represented by a double sided arrow as "
" in a chemical equation.
For example, 
Therefore, we can conclude that when a reaction system is at equilibrium then the rates of the reaction in the forward and reverse directions are exactly equal.
The pressure of the tyre after the temperature change is 0.89atm. Details about pressure can be found below.
<h3>How to calculate pressure?</h3>
The pressure of the tyre can be calculated using the following equation:
P1/T1 = P2/T2
Where;
- P1 = initial pressure
- P2 = final pressure
- T1 = initial temperature
- T2 = final temperature
According to this question, a tyre at 21°C (294K) has a pressure of 0.82 atm. Its temperature decreases to –3.5°C (269.5K).
0.82 × 294 = P2 × 269.5
241.08 = 269.5P2
P2 = 241.08 ÷ 269.5
P2 = 0.895atm
Therefore, the pressure of the tyre after the temperature change is 0.89atm.

Velocity is explained as the *speed and *direction something might move. Speed means moving and Direction means a certain way (not stationary.)
