Molar mass of sulphur dioxide ( SO2) = 64.066 g/mol
Molar mass of  water ( H2O ) = 18.0 g/mol

process:

2 H2S + 3 O2 --> 2 H2O + 2 SO2
<span>
2 * 18 g H2O --------------> 2* 64.066 g SO2
72.0 g H2O ----------------> mass of SO2

mass of SO2 =   72.0 *  2 * 64.066 / 2 * 18

mass of SO2 = 9225.504 / 36

mass of SO2 = 256.264 g

1 mole --------------> 64.066 g
mole SO2 ----------> 256.264

mole SO2 = 256.264 / 64.066

= 4 moles of SO2

hope this helps!.

How much heat is released when 15.7g of methane (c2h6) is combusted if the enthalpy of the reaction is - 1560.7 kj
lyudmila [28]

- 407.4 kJ of heat is released.

<u>Explanation:</u>

We have to write the balanced equation as,

2 C₂H₆(g) + 7O₂ → 4CO₂ + 6H₂O

Here 2 moles of ethane reacts in this reaction.

Now we have to find out the amount of ethane reacted using its given mass and molar mass as,

2 mol C₂H₆ × 30.07 g of C₂H₆ / 1 mol C₂H₆ = 60.14 g of C₂H₆

Heat released = ΔH × given mass / 60.14

                        = - 1560. 7 kj ×15.7 g / 60. 14 g  = -407. 4 kJ

Based on the bond angles in CH4, NH3, and H2O, rank the magnitude of these repulsions. Rank from strongest to weakest repulsion.
morpeh [17]

Answer:

H2O> NH3> CH4

Explanation:

According to valence shell electron pair repulsion theory (VSEPR), bond angles and repulsion of electron pairs depends on the nature of electron pairs on the central atom of the molecule. Lone pairs cause more repulsion (and distortion of bond angles) than bond pairs). Lone pair- lone pair repulsion is greater than lone pair bond pair repulsion.

Water contains two lone pairs on oxygen hence it experiences the greatest repulsion. Ammonia has only one lone pair on nitrogen hence there is lesser repulsion between lone pairs and bond pairs. Methane possess only bond pairs of electrons hence it has the least repulsion.
