HELP
Natalka [10]

Explanation:

To find the amount of product that would be formed from two or more reactants, we need to follow the following steps;

  • Find the number of moles of the given reactants.
  • Then proceed to determine the limiting reactant. The limiting reactant is the one in short supply which determines the extent of the reaction.
  • Use the number of moles of the limiting reactant to find the number of moles of the product.
  • Then use this number of moles to find the mass of the product

Useful expression:

    Mass   =  number of moles x molar mass

Which trends appear as the elements in Period 3 are considered from left to right?
andreev551 [17]

Answer:

Metallic character decreases, and electronegativity increases.

Explanation:

Hello!

In this case, according to the organization of the periodic table, we can see that from left to right, the electronegativity increases as nonmetals are able to attract electrons more easily than metals.

Moreover, in contrast to the previous periodic trend, the metallic character decreases from left to right because the elements tend to decrease the capacity to lose electrons and consequently start attracting them.

Thus, the answer would be: "Metallic character decreases, and electronegativity increases".

Best regards!

Svetradugi [14.3K]
Your question looks a bit incomplete as you have the same contents in options a) and d). According to your list, I can't see the correct answer, but I can give you one.The difference between the potential energy of the products of the potential energy of the reactants is equal to the enthalpy of the reaction.
