Why are the boiling point and freezing point of solutions affected by the concentration of solute particles?

State two differences between metals and non metals with respect to their

Naya [18.7K]

Answer:

Physical Properties

1. Metals are shiny but most non - metals lack this property.

2. Metals are able to deform under compression (malleable) but most non - metals lack this property.

Chemical Properties

1. Metals are good conductorsof heat and electricity but most non - metals are insulators.

2. Metals, when exposed to water atmospheric oxygen tend to rust but non - metals lack this chemical property

A sample of the mineral hematite Iron (III) oxide has a mass of 12.4g. How many moles of the mineral are present?

8090 [49]

Thus problem is providing us with the mass of iron (III) oxide as 12.4 g so the moles are required and found to be 0.0776 mol after the calculations:

<h3>Mole-mass relationships:</h3>

In chemistry, we use mole-mass relationships in order to calculate grams from moles and vice versa. In this case, since we are given the mass of iron (III) oxide as 12.4 g one can calculate the moles by firstly quantifying its molar mass:
