Ionic compounds can be made from a metallic ion and a nonmetallic ion. Metallic ions (M) are positive (cations). Nonmetallic ions (N) are negative (anions). x stands for the number of metallic ions and y stands for the number of nonmetallic ions. For each equation given below, enter the number in the space provided to correctly answer the question.

Explanation:

Since metals have more number of electrons therefore, they donate extra electron(s) in order to gain stability. Whereas non-metals have less number of electrons than metals. Hence, non-metals readily gain electron(s) in order to gain stability.  

Sum for the mentioned entries are as follows.

  • (+1) + (-1) = 1 -1 = 0
  • (+2) + (-2) = 2 - 2 = 0
  • 2(+1) + (-2) = 2 - 2 = 0
  • (+3) + 3(-1) = 3 - 3 = 0
  • 3(+2) + 2(-3) = 6 - 6 = 0

A substance registers a temperature change from 20 to 40 to what incremental temperature change does this correspond
ss7ja [257]

<u>Given:</u>

Initial temperature, T1 = 20 C

Final temperature, T2 = 40 C

<u>To determine:</u>

The temperature change

<u>Explanation:</u>

Convert degree C to Kelvin

Temperature in Kelvin = degree C + 273

T1 = 20 + 273 = 293 K

T2 = 40 + 273 = 313 K

Incremental temperature change = T2 - T1 = 313-293 = 20 K

Ans: The temperature change in kelvin is 20 K

For the reaction N2(g) + 3H2(g) 2NH3(g), what will happen if hydrogen gas was removed from the reaction mixture? There will be a
Hoochie [10]
This uses something called <span>Le Chatelier's principle. It states essentially that any stress put upon a system will be corrected.

In more simple terms, it means that in an equilibrium, such as the equation N2(g) + 3H2(g) <=> 2NH3(g), removing a reactant will cause the system to create more of said reactant to compensate for its loss, or adding excess reactant will cause the system to remove some of the added reactant. For future reference, the same principle applies to products in an equilibrium as well. 

In this case, hydrogen gas is a reactant, and hydrogen is being removed. According to </span><span>Le Chatelier's principle, the system will shift to create more hydrogen gas. In essence, it will shift in the direction of the hydrogen gas, so there will be a shift toward the reactants.

To clear something up, Keq will not change, as it is a constant value with constant conditions (such as temperature, pressure, etc.).</span>
