Suppose that you add 26.7 g of an unknown molecular compound to 0.250 kg of benzene, which has a K f Kf of 5.12 oC/m. With the added solute, you find that there is a freezing point depression of 3.89 oC compared to pure benzene. What is the molar mass (in g/mol) of the unknown compound

Answers

From the calculation, the molar mass of the solution is 141 g/mol.

What is the molar mass?

We know that;

ΔT = K m i

K = the freezing constant

m = molality of the solution

i = the Van't Hoft factor

The molality of the solution is obtained from;

m = ΔT/K i

m = 3.89/5.12 * 1

m = 0.76 m

Now;

0.76 =  26.7 /MM/0.250

0.76 = 26.7 /0.250MM

0.76 * 0.250MM =  26.7

MM= 26.7/0.76 * 0.250

MM = 141 g/mol

if the same amount of heat is added to 50.0 g samples of each of the metals, which are all at the same temperature, which metal will reach the highest temperature?

Answers

The metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

What is the amount of heat added to each metal?

The amount of heat Q = mcΔT where

m = mass of metalc = specific heat capacity of mateal and ΔT = temperature change

Temperature change of the metal

Making ΔT subject of the formula, we have

ΔT = Q/mc

Given that Q and m are the same for each metal,

ΔT ∝ 1/c

We see that the temperature change is inversely proportional to the specific heat capacity.

Since the metals are at the same temperature, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

So, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

From the reaction, we can see that the number of moles produced is 2.5 moles of Na2SO4

What is a reaction?

Chemical reaction involves the combination between two or more species. In this case, the reaction  equation is; 2NaOH + H2S04 ----> Na2SO4 + 2H20.

Now we are told that sulfuric acid is in excess hence NaOH is the limiting reactant.

What type of bond is formed between the following elements/molecules (ionic, polar covalent, or nonpolar covalent)?

Answers

Answer:

1.) Ionic

2.) Nonpolar Covalent

3.) Polar Covalent

Explanation:

Ionic bonding generally occurs when a metal and nonmetal wish to donate/receive electrons from each other. These bonds are between two atoms with a large electronegativity difference. In the first diagram, potassium (K) is a metal and chlorine (Cl) is a nonmetal. As you can see, after the reaction, potassium donates an electron to chlorine.

Nonpolar covalent bonding occur when atoms of practically the same electronegativity combine. As such, atoms of the same nature have a zero electronegativity difference and thus always form these bonds.

Polar covalent bonding generally occurs between two nonmetals. These atoms have an intermediate size electronegativity difference. Carbon (C) and chlorine satisfy this rule.
