The best electrical conductor is:
rodikova [14]

Answer:

B

Explanation:

Solutions of substances that can conduct electricity are termed electrolytes. These solutions allow electricity to pass through them.

How strong a solution is to allow the passage of electricity is strongly dependent upon the availability of charge carriers within the solution matrix. In sharp contrast to the other solutions in the question, we can see that the presence of sodium and chloride ions in the matrix provides a boost for the solution to act properly as an electrolyte. Hence, it is a better solution than the rest of the options to serve as an electrical conductor

You mix 340 grams of MgBr2 with 8 kg of water. What is the molality of your solution?
Bad White [126]
Given mass of solute = 340 gram
Molar mass of solute(MgBr2) = 184 g

Number of moles = Given mass / Molar mass = 340 / 184 = 1.85 moles

Now, Molarity = Number of moles / solution (in litres)

So, M = 1.85 / 8
M = 0.23 M

In short, Your Molarity would be: 0.23 M

Hope this helps!

Molecule contains carbon, hydrogen and sulfur atoms. When a sample of 0.535g of this compound is burnt in oxygen, 1.119 g of CO2
OLga [1]

Answer:

The empirical formula is, C4H4S

Explanation:

Number of moles of carbon = 1.119 g/ 44g/mol = 0.025 moles

Mass of Carbon= 0.025 moles × 12 g/ mole = 0.3 g

Number of moles of hydrogen = 0.229/18g/mol × 2 = 0.025 moles

Mass of hydrogen = 0.025 moles × 1 = 0.025 g

Number of moles of sulphur = 0.407g/ 64 g/mol = 0.0064 moles

Mass of sulphur= 0.0064 moles ×32 = 0.2 g

Now we obtain the mole ratios by dividing through by the lowest ratio.

C- 0.025 moles/ 0.0064 moles, H- 0.025 moles/ 0.0064 moles, S- 0.0064 moles/0.0064 moles

C4H4S
