D = m/v
0,7857 = m/19.26
m = 0.7857 x 19.26 = 15.132582 g
Answer:
The bond angle between the p orbital is assumed to be 90 degrees But according to VSEPR theory, as molecular geometry is a little bit bent thus the angle is less than 109.5 degrees.
Explanation:
IN hydrogen sulfide, H_2 S, both hydrogen atoms consist of para-magnetic 1s orbital while sulfur consists of diamagnetic 3s and 2 para magnetic 3p orbital.
The bond angle between the p orbital is assumed to be 90 degrees But according to VSEPR theory, as molecular geometry is a little bit bent thus the angle is less than 109.5 degrees.

Answer:
Q4. 2H₂ + O₂ ⟶ 2H₂O; 5; 2
Q5. 24; 30; H₂; 0; 5
Explanation:
Q4.
The equation for the reaction is
2H₂ + O₂ ⟶ 2H₂O
One O₂ molecule reacts with 2H₂ molecules.
We started with seven oxygen molecules. Five of them reacted, so
Two O₂ molecules did not react.
Q5.
Two water molecules form from two hydrogen molecules.
Two water molecules form from one oxygen molecule
Hydrogen forms fewer water molecules of water, so
Hydrogen is the limiting reactant.
The 24 hydrogen molecules will be completely used up.
The number of hydrogen molecules remaining at the end of the reaction is zero.
They have reacted with 12 O₂ molecules.
The number of O₂ molecules remaining is 17 - 12 = 5
