Answer:

\boxed {\boxed {\sf Ionic \ bond}}

Explanation:

First, let's look at the Periodic Table.

We see that aluminum is a metal, while oxygen is a non-metal.

Now, let's recall three types of bonds

  • Ionic: typically forms between a metal and a non-metal
  • Covalent: usually forms between non-metals
  • Metallic: tends to form with metals

Since we have a metal (Al) and a non-metal (O), aluminum oxide must have an <u>ionic bond.</u>

How many molecules are in 2.38g of SO2
Murrr4er [49]

2.63 x 10^22 molecules of SO2.

To find this, start with what you know.

2.38g of SO2.

You need to first convert this into Moles since you cannot directly convert grams into molecules. In order to convert grams to moles, you need to find the molecular mass of SO2 - 64.066.

This is because Sulfur has the mass of 32.066 and Oxygen has a mass of 16, but since there are two Oxygen atoms, it's going to be 32.

Your equation should currently appear as so:

2.38g of SO2 = 1 Mole of SO2 / 64.066

Now, you need to convert this to molecules.

Whenever you are searching for molecules without a given amount, you always use Avogadro's number: 6.02 x 10^23

Now, your equation should appear as so:

2.38g SO2 = 1 Mole of SO2 / 64.066 next to a new fraction which is 6.02 x 10^23 / 1 Mole of SO2

Now, multiply across (2.38 x 1 x 6.02 x 10^23). When using Avogadro's number, don't forget to place parenthesis around it.

Then, divide that number by the bottom: 64.066.

Thus, your final answer is that there is 2.63 x 10^22 molecules of SO2.

Don't forget your units!

Hope this helps!

Calculate the volume of a sample of aluminum that has a mass of 3.057 kg. The density of aluminum is 2.70 g/cm3 (taking into con
Misha Larkins [42]

Answer:

v = 1130 cm³

Explanation:

Given data:

Volume of sample = ?

Mass of Al sample = 3.057 Kg (3.057 Kg× 1000g/1 Kg = 3057g)

Density of Al sample = 2.70 g/cm³

Solution:

Formula:

d = m/v

d = density

m = mass

v= volume

by putting values

2.70 g/cm³ = 3057g /v

v = 3057g /2.70 g/cm³

v = 1130 cm³

4.2 g of lithium (Li) reacts with 2.8 g of nitrogen (N2). Find the simplest molar ratio in which lithium reacts with nitrogen.
o-na [289]

The simplest molar ratio in which lithium reacts with nitrogen is 6 moles of lithium to 1 mol of nitrogen.

What is molar ratio?

A molar ratio examines the ratio that exist between two chemical compounds showing the amounts in moles of the compounds involved in a chemical reaction.

Molar ratio = amount of a constituent in moles ÷ total amount of all constituents in a mixture in moles

Given:

Mass of lithium (Li) = 4.2 g

Mass of  nitrogen (N2) = 2.8 g

Total amount of mass = 7g

Moles = molecular weight  ÷  mass of water

Moles of lithium (Li) = 4.2 ÷ 7 = 0.60 mol

Moles of nitrogen (N₂) = 2.8 ÷ 7 =  0.10 mol

Therefore, ratio Li : N₂ = 0.60 : 0.10 = 6 : 1

6 Li + N₂

The balanced equation between lithium and nitrogen, to form lithium nitride = 6 Li + N₂ → 2 Li₃N₆L i + N₂ → 2Li₃N

In summary, the simplest molar ratio in which lithium reacts with nitrogen is 6:1
