Answer:

0.43 grams is the maximum mass of sodium sulfate that could be produced by the chemical reaction.

Explanation:

Mass of sulfuric acid = 0.98 g

Moles of sulfuric acid = \frac{0.98 g}{98 g/mol}=0.010 mol

Mass of sodium hydroxide = 0.240 g

Moles of sodium hydroxide = \frac{0.240 g}{40 g/mol}=0.0060 mol

H_2SO_4(aq)+2NaOH(s)\rightarrow Na_2SO_4(aq)+2H_2O(l)

According to reaction, 2 moles of sodium hydroxide reacts with 1 mole of sulfuric acid , then 0.0060 moles of sodium hydroxide will react with :

\frac{1}{2}\times 0.0060 mol=0.0030 mol of sulfuric acid

As we can see that we have 0.010 moles of sulfuric acid but only 0.0030 moles of sulfuric acid will react which indicates that it is in excessive amount where as sodium hydroxide is in limiting amount.

So, amount of sodium sulfate to be formed will depend upon moles of sodium hydroxide.

According to reaction, 2 moles of sodium hydroxide gives with 1 mole of sodium sulfate , then 0.0060 moles of sodium hydroxide will give :

\frac{1}{2}\times 0.0060 mol=0.0030 mol of sodium sulfate

Mass of 0.0030 moles of sodium sulfate :

0.0030 mol × 142 g/mol = 0.426 g ≈ 0.43 g

0.43 grams is the maximum mass of sodium sulfate that could be produced by the chemical reaction.

1.) What are the chemical properties of matter?
denis23 [38]

Answer:

Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

What Happens During Fermentation?
Stella [2.4K]

Answer:

Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol.

Sometimes bacteria perform fermentation, converting carbohydrates into lactic acid...
