Explanation:
The wood turns into ash and smoke so mass is nor destroyed or created.
The mass of sodium chloride used <u>was 1.17 grams</u><u>.</u>
The mole fraction can be calculated by way of dividing the number of moles of 1 factor of an answer via the full variety of moles of all the additives of an answer. it is mentioned that the sum of the mole fraction of all the components inside the solution has to be the same as one.
mass of NaCl given = 64.9 g
mole = mass/molar mass
= 64.9 / 58.5
=<u> 1.109</u>
a mole fraction of water = 0.980
mole fraction of NaCl = 1 - 0.980
= <u>0.02</u>
1 mole of NaCl = 58.5
mass of NaCl = 58.5 × 0.02
=<u> 1.17 gram</u>
Mole Fraction describes the range of molecules contained within one aspect divided through the whole range of molecules in a given combination. it's miles quite beneficial whilst two reactive-natured components are mixed collectively.

Ok so O3 has a greater electronegativity and is taken into account first, -2*3=-6, so As has to equal 6/2=3, so As has a +3 oxidation number here
The acid and alkali that would react to make sodium sulfate is
alkali= sodium hydroxide
acid = sulphuric acid
<u><em>explanation</em></u>
Acid react react with alkali to form salt and water.
For sodium sulfate salt to be formed a sulfate acid is required to react with a hydroxide of sodium .
therefore Sodium hydroxide (alkali) react with sulphuric acid (an acid) to form sodium sulfate (salt) and water.
