Given the equation: HCl + Na2SO4 → NaCl + H2SO4, if you start with 8 moles of hydrochloric acid, how many grams of sulfuric acid
Simora [160]

Answer:

392g sulfuric acid are produced

Explanation:

Based on the balanced equation:

2HCl + Na2SO4 → 2NaCl + H2SO4

<em>2 moles of HCl produce 1 mole of sulfuric acid</em>

<em />

To solve the problem we need to find the moles of sulfuric acid produced based on the chemical equation. Then, using its molar mass -<em>Molar mass H2SO4 = 98g/mol- </em>we can find the mass of sulfuric acid produced:

<em>Moles sulfuric acid:</em>

8mol HCl * (1mol H2SO4 / 2mol HCl) = 4 mol H2SO4

<em>Mass sulfuric acid:</em>

4mol H2SO4 * (98g / mol) =

392g sulfuric acid are produced

fomenos

Answer:

He assumed wrongly

Explanation:

It happened this way because the person assumed wrongly.

Most other compounds have the same physical appearance as water especially when in liquid form.

  • This can be a very tricky one in the laboratory.
  • The sense of taste is not the best way to fathom what a particular compound is made up of.
  • This is the reason why this student or person faced this sort of problem.
  • Water has different properties that can be tested for using simple techniques in the laboratory.
