Answer:
Rotting, burning, cooking, are the three example of a chemical change.
The correct answer is option D. i.e.<span>All states of matter show random motion of particles.ding to the kinetic theory
According to the kinectic theory of matter, all the particles show random motion at the room temperature. Decreasing the temperature to absolute zero temperature i.e. 0 K will cease the motion of particles.</span>
Answer:
Adding more of gas C to the system
Explanation:
- <em>Le Châtelier's principle</em><em> states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>
1) Adding more of gas C to the system:
Adding more C gas will increase the concentration of the products side. So, the reaction will be shifted to the left to attain the equilibrium again.
2) Heating the system:
Heating the system will increase the concentration of the reactants side as the reaction is endothermic. so, the reaction will be shifted to the right to attain the equilibrium again.
3) Increasing the volume:
has no effect since the no. of moles of gases is the same in both reactants and products sides.
4) Removing some of gas C from the system:
Removing some of gas C from the system will decrease the concentration of the products side. So, the reaction will be shifted to the right to attain the equilibrium again.
<em>So, the right choice is: Adding more of gas C to the system.</em>
<em></em>
Starting on hydrogen going down the atomic radius goes up. And hydrogen to the right the atomic radius becomes smaller.
