Cadium

Down a period, atomic radii decrease from left to right due to the increase in the number of protons and electrons across a period.

In a calorimeter, 10.0 g of ice melts at 0oC. The enthalpy of fusion of the ice is 334 J/g.

d1i1m1o1n [39]

Answer:

Explanation:

In the problem above it is

q = mass x heat fusion

q = 10 g x 334 J/g = 3340 J. Since the ice is absorbing heat it is + 334 J.

What is the molality of a solution made by dissolving 2 moles of NaOH in 10 kg of water?

zaharov [31]

Answer:

0.2mol/kg

Explanation:

molality is the concentration of a solution in moles of solute per kilogram of solvent

moles of solute (NaOH) = 2moles

mass of solvent in kg. =10kg

Therefore molality. = 2moles/10 kg

=0.2mol/kg

chemist adds of a M iron(III) bromide solution to a reaction flask. Calculate the mass in grams of iron(III) bromide the chemist

Sav [38]

The question is incomplete, here is the complete question:

A chemist adds 370.0 mL of a 2.25 M iron(III) bromide solution to a reaction flask. Calculate the mass in grams of iron(III) bromide the chemist has added to the flask. Round your answer to 3 significant digits

Answer: The mass of iron (III) bromide is 246. grams

Explanation:

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Molarity of solution = 2.25 M

Molar mass of iron (III) bromide = 295.6 g/mol

Volume of solution = 370.0 mL

Putting values in above equation, we get:

$2.25M=\frac{\text{Mass of solute}\times 1000}{295.6\times 370.0}\\\\\text{Mass of solute}=\frac{2.25\times 295.6\times 370.0}{1000}=246.1g$

Hence, the mass of iron (III) bromide is 246. grams
