Answer:

2 moles of SO₂

Explanation:

Equation of reaction

H₂S + 3H₂SO₄ → 4H₂O + 4SO₂

From the equation of reaction above,

1 mole of H₂S will produce 4 moles of SO₂

1 mole of H₂S = 4 moles of SO₂

0.5moles of H₂S = zmoles of SO₂

z = (0.5*4) / 1

z = 2 moles of SO₂

0.5 moles of H₂S will produce 2 moles of SO₂

When water vapor changes to a liquid what is it called

Mademuasel [1]

Answer:

$hello \: your \: answer \: is \: here.$

Explanation:

<h2>Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.</h2>

When 500.0 g of water is decomposed by electrolysis and the yield of hydrogen is only 75.3%, how much hydrogen chloride can be m

Evgen [1.6K]

The amount of hydrogen chloride that can be made is 1064 g

Why?

The two reactions are:

2H₂O → 2H₂ + O₂ 75.3 % yield

H₂ + Cl₂ → 2HCl 69.8% yield

We have to apply a big conversion factor to go from grams of water (The limiting reactant), to grams of HCl, the final product. We have to be very careful with the coefficients and percentage yields!

$500.0gH_2O*\frac{1moleH_2O}{18.01 gH_2O}*\frac{2 moles H_2}{2 moles H_2O}*\frac{2.015g H_2}{1 mole H_2}*\frac{75.3 actual g}{100 theoretical g}=42.12 g H_2$

$42.12H_2*\frac{1 mole H_2}{2.015gH_2}*\frac{2 moles HCl}{1 mole H_2}*\frac{36.46g}{1 mole HCl}*\frac{69.8 actualg}{100 theoreticalg} =1064gHCl$

Have a nice day!

Which property of table salt is also a property of other ionic compounds

Svet_ta [14]

Most likely it’s crystalline structure, which makes it small granules that are soluble in water. Most, if not all, ionic compounds are salts. And salts dissolve in water.

Hope that’s correct

Why is acetic anhydride added slowly to a dichloromethane solution of the other reactants?

storchak [24]

Acetic anhydride is the only monocarboxylic acid anhydride which is an acylating agent capable of modifying reactions. The dichloromethane is the reaction solvent.

The acetic anhydride should be added slowly through a separatory funnel to other reactants so as to avoid a runaway reaction, also known as thermal runaway. By doing this the reaction mixture boils as gently as possible while stirring. This phenomenon occurs in situations where an increase in temperature changes the conditions in a way that leads to destructive result brought about by a further increase in temperature.
