54. Write a formula for the ionic compound that forms from

1 answer:

3 0

Answer:
a) Al2O3

Explanation:
Aluminum generally forms Al3+ ions.
Oxygen generally forms O2− ions.

So when the metal and the non-metal bond together they form a neutral compound, i.e. Al2O3
(i.e. 2×3−3×2=0).

The ionic bonding is so strong (due to charge magnitude) in this material that it is reasonably insoluble.

To what volume should you dilute 60.0 mL of a 4.50 M KI solution so that 30.0 mL of the diluted solution contains 3.25 g of KI?

SpyIntel [72]

Answer:

You should dilute to 414.1 mL

Explanation:

Let's apply the dilution formula to solve this:

M conc . Vol conc = M dil . Vol dil

Molarity for concentrated solution → 4.50 M

Volume for concentrated solution → 60 mL

Molarity for diluted solution → Unknown

Volume for diluted solution → Answer

Let's determine the molarity for diluted solution with data given.

We convert the mass of KI to moles

3.25 g . 1 mol/166 g = 0.0195 moles

Let's convert the volume from mL to L

30 mL . 1 L/1000mL = 0.030 L

Molarity (mol/L) = 0.0195 mol /0.030L = 0.652 M

We replace the data in the formula

4.50 M . 60 mL = 0.652 M . Volume for diluted solution

(4.50M . 60mL) / 0.652M = Volume for diluted solution

414.1 mL = Volume for diluted solution

It is a graph. It shows observations and then you record your results with any of the graph types.
