Explanation:
Which of the following shows a chemical reaction in which
Ask: Which of the following shows a chemical reaction in which magnesium and hydrogen sulfide are the reactants and magnesium sulfide and hydrogen are the products? A. magnesium sulfide + hydrogen → magnesium + hydrogen sulfide B. magnesium + magnesium sulfide → hydrogen sulfide + hydrogen C. magnesium + hydrogen sulfide → magnesium sulfide + hydrogen D. magnesium + hydrogen → magnesium sulfide + hydrogen sulfide
Answer: C. magnesium + hydrogen sulfide → magnesium sulfide + hydrogen
In chemical reactions, it always involve both reactants and products. Reactants are the substances that start a chemical reaction, and products are substances that are produced in the reaction. Reactants are usually at the left of the tail of the arrow (→ ) and products are at the right or tip of the arrow (→) if it is forward reaction. And if it is backward reaction, it is the reverse of the forward reaction.
Given: Reactants: magnesium, hydrogen sulfide
Products: magnesium sulfide, hydrogen
Answer: magnesium + hydrogen sulfide → magnesium sulfide + hydrogen
spdf magnesium need good answer
Ask: spdf magnesium
need good answer
Answer:
We’ll put six in the 2p orbital and then put the remaining two electrons in the 3s. Therefore the Magnesium electron configuration will be 1s22s22p63s2. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.

In a reaction with hydrochloric acid, why does powdered magnesium
Ask: In a reaction with hydrochloric acid, why does powdered magnesium reacts faster than the same mass of magnesium ribbon?a. The powdered magnesium contains more atoms than the magnesium ribbon.b. The powdered magnesium is hotter than the magnesium ribbon.c. The powdered magnesium has a bigger surface area than the magnesium ribbon.d. The powdered magnesium has a smaller surface area than the magnesium ribbon.
Answer:
The powdered magnesium reacts faster than the magnesium ribbon because the powdered magnesium has a bigger surface area than the magnesium ribbon.
Explanation:
Kinetics is the study of the speed of chemical reaction. Some chemical reactions proceeds very fast while others are slow. Depending on what is being observed or needed, Chemists tend to slow down or speed up a chemical reaction. There are several factors that affect chemical reactions.
Some factors are listed below:
- Concentration of reactants
- Pressure of gaseous reactants
- Nature of reactants
- Particle size of reactants
- Temperature
- Catalyst
For the situation given, the magnesium compounds in the reaction contain the same mass but differ in particle size. One is powdered and the other is in the form of a ribbon. Particle size will be our basis of our analysis.
Powdered substances have bigger surface areas. Increase in surface area of a solid reactant exposes more of its particle to come in contact with the other reactant. This will result to more collision between reactant particles, hence, speeding up the reaction.
