HELP PLEASEEEE

Chemistry
1 answer:
kifflom [539]2 years ago
6 0

Explanation:

So first find out the moles. The percentage is out of 100 so just convert the percentage into mass by just changing the sign.

Ga = 55g/69.7 = 0.789 moles

F=45g/19 = 2.37 moles

Then divide by smallest value to find out the formula

Ga=0.789÷0.789= 1

F=2.37÷0.789 = 3

GaF3

hope this helps:)

so here we will get product with inverted geometry

In SN2 mechanism the nucleophile attacks from back side and we always get product with inverted geometry

This is known as Walden inversion.

5. Balance the following reactions using either the oxidation number method or the half-reaction
stich3 [128]

The balanced reaction equations are;

a) 4 NaClO + H2S → 4 NaCl + H2SO4

b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O

<h3>What is a balanced redox reaction?</h3>

A redox reaction is said to be balanced when the number of electrons gained is equal to the number of electrons lost.

Let us now write the balanced reaction equations one after the other. Thus;

a) 4 NaClO + H2S → 4 NaCl + H2SO4

b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O
