This would be true for dimensional analysis / Stoichiometry questions
Answer:
The Correct Answer is A and C.
Explanation:
- The wind is the movement of air, the movement of air is happened by the difference in pressure.
- A difference in air pressure is what causes the wind to blow. Difference in pressure is happened by the uneven heating of the earth's surface.
- The wind is normally moving air from a high air pressure place to a low air pressure place.
- The greater the difference in air pressure the stronger the wind blow.
Answer: Option (A) is the correct answer.
Explanation:
A catalyst is a substance which helps in increasing the rate of a reaction without itself getting consumed in the reaction.
A catalyst lowers the activation energy of a reaction so that reactant molecules with less energy can easily participate into the chemical reaction and thus, product formation becomes faster.
Thus, we can conclude that adding a catalyst to the reaction would reduce the activation energy of a chemical reaction.
Ik it's not magnesium because that was my first answer. The correct answer would be Sulfur. Sulfur is a non metal. All the other answers are good conductors of heat
