1 mole of MgS = 24.3 + 32.1 = 56.4 g
35.1 g MgS x 1 mol / 56.4 g = 0.622 mol
M = 0.622 mol / 0.835 L = 0.745 mol/L

Propene has three electron groups surrounding the core carbon atom, as seen in the Lewis dot structure of the compound.
<h3>What is Lewis dot structure?</h3>
A Lewis Structure is a greatly condensed illustration of a molecule's valence shell electrons. It is used to display how the electrons are positioned around particular molecules' atoms. When two atoms are bonded together, electrons are depicted as "dots" or as a line.
Lewis structures, often referred to as Lewis dot formulas, electron dot structures, or Lewis electron dot structures, are diagrams that depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

Answer: metallic solid
Explanation:
Copper is a metallic crystalline solid. A metallic solid is an element that can withstand high temperatures and conduct electricity.
Answer:
option b is correct
Explanation:
Taking the Van't Hoff equation
d ln Keq / dT = ΔH/(RT²)
then
Keq increases with increasing temperature (d ln Keq / dT>0) when ΔH>0 and decreases with increasing temperature (d ln Keq / dT<0) when ΔH<0
if Keq decreases (reactions shift toward reactants) from 7.9×10³ to 0.77 when temperature increases from 298 K to 713 K (d ln Keq / dT<0) → ΔH<0 ( exothermic reaction)
therefore option b is correct
