Kc = [CS2] / [S2][C] but, since C is solid, it doesn't fit here
<span>Kc = [CS2] / [S2] </span>
<span>S2(g) + C(s) ---> CS2(g) </span>
<span>13.8mole S2 / 6.05L = 2.28M </span>
<span>Kc = x / 2.28-x </span>
<span>9.4 x (2.28-x) = x </span>
<span>21.43 - 9.4x = x </span>
<span>21.42 = 10.4x </span>
<span>x = 2.05M = [CS2] </span>
<span>2.05M x 6.05L = 12.46moles </span>
<span>12.46moles x 76gmole = 946.96g CS2</span>
Answer:
D. Dense, conducts electricity, high melting point, giant structure, brittle
Explanation:
Graphite is an allotrope of carbon. It is similar to diamond except for some differences in their properties and mode of formation.
Graphite is typically a non-metal and should have properties of non-metals. Metals are malleable, ductile, conducts electricity, etc.
Graphite is able to conduct electricity because of the presence of free mobile electrons in its structure.
It is dense but its density is lower than that of diamond but higher than water.
Graphite is brittle with a high melting point which is close to that of diamond.
<span>There are a number of ways
to express concentration of a solution. This includes molarity. It is
expressed as the number of moles of solute per volume of the solution. To convert the mass of the solute to moles, we use the molar mass of the substance. We calculate as follows:
MOlarity = 4.725 g ( 1 mol / 58.45 g ) / .5 L = 0.162 mol / L</span>
