The formation equation for carbon monoxide is:
C(s) + 1/2O2(g) --> CO(g).
We know that all of the elements and compounds are on the correct sides of the equations (C and O on left and CO on the right). The coefficients are also correct, so all we have to do is cancel out. The CO2's cancels out, and the O2's cancel out and leave a 1/2O2 on the top reaction. Finally, all we have to do is add up the heats of reactions for our final answer. As -393.5 + 283.0 = -110.5, our final answer is -110.5 kJ.

Hope this helps!

Compare the ability to hold on to / attract electrons between metals and nonmetals.
skad [1K]

Nonmetals have the ability to attract electrons better than metals because they have a higher electron affinity or electronegativity than metals.

<h3>What is electronegativity?</h3>

Electronegativity is the tendency, or a measure of the ability, of an atom or molecule to attract electrons and thus form bonds.

An element in the periodic table with a high electronegativity will automatically have a high electron affinity.

Metals (low electronegativity) are known to lose electrons to non-metals (high electronegativity), hence, nonmetals have the ability to attract electrons better than metals because they have a higher electron affinity or electronegativity than metals.

Which of the following compounds is likely to make the best conductor when
Gnoma [55]

Answer:

c. KBr .

Explanation:

Hello!

In this case, since electrolytes are substances that are able to carry electric current in the form of electrons via ions, those that are ionic are said to have the greatest capacity to conduct the electricity; in such a way, since SO2, C6H12O6 and CO are non-ionic molecules but covalent, they are not good conductor, therefore the best conductor would be c. KBr as it is an ionic compound due to the electronegativity of the K-Br bond.

Best regards!
