Answer:
Is this an actual question that you had for school?
Explanation:
The 2 trends that are commonly seen in modern concentration
chart , first it is increasing. Since the star of industrial revolution the
amount of co2 increases with time. The second trend is that the temperature
also increases because it is a green house gas which causes the global warming.
Mass of Na2SO4= 514.18 grams
<h3>Further explanation</h3>
Given
423.67 g of NaCl
Required
mass of Na2SO4
Solution
Reaction
2NaCl + H2SO4 → Na2SO4 + 2HCl
mol NaCl :
= 423.67 g : 58.5 g/mol
= 7.24
From the equation, mol Na2SO4 :
= 1/2 x mol NaCl
= 1/2 x 7.24
= 3.62
Mass Na2SO4 :
= 3.62 mol x 142,04 g/mol
= 514.18 grams
