The correct answer is they will not necessarily be equal, but they will be constant. The change between reactants and products will be going continuously but the concentration is constant.

explain why metals conduct electricity in their solid forms but ionic compounds do not. you may use a picture to support your an
deff fn [24]

Explanation:

Ionic solids are defined as the solids in which atoms of opposite charge are held together by strong forces of attraction. As a result, in solid state these atoms are not present in free state.

Hence, they cannot move as ions from one place to another. On the other hand, metals are able to conduct electricity because of the presence of free electrons in it.

As we know that electricity is the flow of ions or electrons from one place to another. Therefore, metals are able to conduct electricity in their solid state.

Determine the molecular weight for mg(no3)2.
Gekata [30.6K]
Molecular Weight (MW) is the sum of the atomic weights/masses (AM) of every atom in a compound or molecule. Thus, we would add the AM of Mg + 2×[N+(O×3)]:
Mg = 24.31
N = 14.01
O = 16
So we have: Mg + 2×[N+(O×3)] = 24.31 + 2×[14.01+(16×3)] = 24.31+2×[14.01+48] = 24.31+ 2×62.01 = 24.31+124.02 = 148.33

C) is the correct answer

A chemical reaction was run in 210.0 mL of H2O. During the reaction, the temperature of the H2O changes from 27.2 oC to 57.6 oC.
AnnZ [28]

Answer:  The quantity of heat produced by the reaction is +26710.656J

Explanation:

Quantity of Heat, Q = mass * specific heat capacity *temperature change

Q = mCpTc, where m= mass, Cp= specific heat capacity, Tc is temperature change

m= 210.0g, Cp=4.184J/(g · oC), Tc= 57.6 - 27.2 = 30.4 oC

Q = 210.0g *4.184J/(g · oC) * 30.4 oC

Q = +26710.656J

Therefore, the quantity of heat produced by the reaction is +26710.656J.

Note: <em>Even though heat is given out by the system and is normally written as a negative value to indicate that heat is lost, the answer is written as a positive decimal number according to instruction.</em>
