Answer:
B.) The reaction will shift to the right to produce more product.
Explanation:
When the pressure of a reaction is increased, the equilibrium shifts to the side with less moles of gas.
You can determine the moles of gas by adding the coefficients on each side of the reaction. The reactants have 4 moles of gas (1 + 3 = 4) and the products have 2 moles of gas. Since there are less moles of gas on the product side, the equilibrium will shift to that side. As such, more product will be produced.
The right option is; a pure substance and an element.
A piece of sodium metal can be described as a pure substance and an element.
Sodium is a chemical element with an atomic number of 11. Sodium is a soft, waxy, silvery, highly reactive metal. Sodium belongs to group 1 of the periodic table and it is highly abundant in the earth’s crust. Sodium can also be found in various minerals such as rock salt, feldspars and sodalite.
Answer:
Explanation:
The atomic mass of <em>nickel</em> is 58.963g/mol. Thus, one mole of nickel weighs "exactly" 58.693g.
How much nickel does every coin contain?
How many times 58.693g contains 1.25g?
That means that you need to have 47 coins of nickel to have one mole of nickel.
Answer: The answer is A
Explanation: No because it’s is a mixture because physical methods were used to separate its particals
