1. What are Linus Pauling Contributor notable in science?
Answer:
Best known to the public for championing the use of vitamin C for health purposes and for winning the Nobel Peace Prize, Linus Carl Pauling (1901–1994) was revered by his fellow scientists as a prolific researcher who made significant contributions to our understanding of chemical bonding and chemical structure.

3. Krypton The first scale of electronegativity was developed by Linus Pauling and on his scale krypton has a value of 3.00 on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine).
Answer:
Explanation:
Krypton, an element in the periodic table with the symbol Kr and atomic number 36, has a value of 3.00 on the electronegativity scale developed by Linus Pauling. This scale was created to measure the ability of an atom to attract electrons towards itself when it is part of a molecule. The scale ranges from 0.7, an estimated value for francium, to 2.20 for hydrogen, to 3.98 for fluorine. Krypton falls in the middle of the scale, indicating that it has moderate electronegativity. This property is important in chemical reactions and bonding, as atoms with higher electronegativity tend to attract electrons more strongly, creating more polar bonds.

8. 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 reactantsPressure of gaseous reactantsNature of reactantsParticle size of reactantsTemperatureCatalystFor 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.

9. Magnesium+oxygen magnesium oxide+oxygen
Answer:
Magnesium reacts with oxygen to produce magnesium oxide.
...
Example.
Step Result
1 magnesium + oxygen → magnesium oxide
2 Mg + O 2 → MgO
3 reactants: 1 × Mg, 2 × O products: 1 × Mg, 1 × O Not balanced.
4 Mg + O 2 → 2MgO
When magnesium reacts with oxygen, it produces light bright enough to blind you temporarily. Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO).

18. how many atom of magnesium are in 123 g magnesium?
Answer:
Magnesium cyanide has the chemical formula MG(CN)2. First, we must solve for the number of moles of magnesium cyanide. This is done by dividing the given mass by the molar mass:
Solving for the molar mass of magnesium cyanide:
Mg - 24.305 x 1 = 24.305 g/mol
C - 12.01 x 2 = 24.02 g/mol
N - 14.01 x 2 = 28.02 g/mol
24.305 + 24.02 + 28.02 = 76.345 g/mol
Solving for the number of moles:
123 g = 1.61 moles
76.345 g/mol
Avogadro's number tells how many particles are present in one mole of a substance. We can solve for the number of molecules by multiplying the number of moles by Avogadro's number:
6.022 x 10²³ molecules
1.61 moles x 1 mole = 9.695x10²³ molecules
But each molecule of magnesium cyanide contains one atom of magnesium and two each of carbon and oxygen, for a total of 5 atoms. So we must multiply the computed number of molecules by 5:
9.695 x 10²³ x 5 = 4.58 x 10²¹ atom
Therefore, there are 4.85×1024 atoms.

24. 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
