Acids:
Sulfuric acid, hydrochloric acid, nitric acid,
Bases:
Potassium hydroxide (KOH)
Sodium hydroxide (NaOH)
Barium hydroxide (Ba(OH)2)
Answer:
2H+ + 2e - ---> H2(g) is the cathode
2Cl - ---> Cl2(g) + 2e - is the anode
Explanation:
Hydrogen ion has gained two electrons, making it undergo reduction. While chlorine has lose two electrons, hence undergoing oxidation.
Answer:
Hey there
Explanation:
The process where organisms better adapted to their environment tend to survive and produce more offspring is called natural selection. It is one of the points of Darwinism by Charles Darwin.
Hope it helps
<h3>Answer:</h3>
Molecules Collide more frequently
<h3>Explanation:</h3>
The factors which effect the rate of reactions are as follow,
Concentration:
Increase in concentration of reactants will increase the number of reactants per unit volume. Therefore, the probability of collisions will increase hence, it will result in the increase in yield.
Temperature:
Increase in temperature increases the kinetic energy of reactants. Therefore, the increase in velocity of reactants results in the collisions with high energy. It makes it feasible for reactants to attain the optimum energy (activation energy) to convert into products with good yield.
Surface Area:
The reactants in grinded / powder form reacts fast as compared to solid form. In fact, grinding results in increase of the surface area of reactants. Greater surface area increases the probability of reactants to colloid. Hence, increases the yield.
<h3>Conclusion:</h3>
As shown, all the given factors are related to collisions of molecules or atoms hence, the option selected is the correct option.
