RideAnS [48]3 years ago
4 0

Answer:

By far the most abundant volcanic gas is water vapor, which is harmless. However, significant amounts of carbon dioxide, sulfur dioxide, hydrogen sulfide and hydrogen halides can also be emitted from volcanoes.

CORRECT ANSWER ONLY ND WILL GIVE BRAINLIEST✌
alexira [117]

Answer:

150g

Explanation:

Assuming they are ideal gases at the same temperature and pressure, equal moles of gasses have equal volume. IN this case, if we have 10g of hydrogen gas, that is 5 moles of H2 gas. That means 5 moles og NO2 will occupy the same volume which is 5*(14.0 + 16.0*2) =  230 g

Al + h2so4 → al2(so4)3 + h2 when the equation is correctly balanced, the coefficient of h2so4 is -
Yuri [45]
First, we have to balance the equation:

Al +  H2SO4 → Al2(SO4)3 + H2

we have the number of Al atoms not equal on both sides so we will put 2 Al instead of Al on the left side of the equation.

2Al + H2SO4  → Al2(SO4)3 + H2 

now we have an unequal number of (SO4) group on both sides of the equation so we put  3H2SO4 instead of H2SO4

2Al + 3H2SO4 → Al2(SO4)3 + H2

now, we have to put 3H2 instead of H2 to make the H atoms equals on both sides.

2Al + 3H2SO4 → Al2(SO4)3 + 3H2 this is the final balanced equation.

∴ the coefficient of  H2SO4 is 3

Please help, what would the theoretical yield of this be? I don’t understand how to do this.
Ronch [10]

The theoretical yield : = 28.34 g Al₂O₃

<h3>Further explanation</h3>

Given

15 g of Aluminum react

Required

The theoretical yield

Solution

Reaction

4Al(s) + 3O₂ (g)⇒ 2Al₂O₃(s)

mol of Aluminum :

mol = mass : Ar Al

mol = 15 g : 26.98 g/mol

mol = 0.556

From the equation, mol ratio of Al : Al₂O₃ = 4 : 2, so mol Al₂O₃ :

= 2/4 x mol Al

= 2/4 x 0.556

= 0.278

Mass Al₂O₃ :

= mol x MW Al₂O₃

= 0.278 x 101.96

= 28.34 g
