The answer is A mutualism
If a molecule has four hybrid sp3 orbitals, it can be concluded that the molecule has a TETRAHEDRAL GEOMETORY
Answer:
A
Explanation:
Protons are positive
Neutrons are neutral
Electrons are negative
Protons and Neutrons are in the nucleus
Electrons are orbiting around the nucleus
the balanced equation for the formation of water is as follows
2H₂ + O₂ ---> 2H₂O
molar ratio of oxygen to water is 1:2
mass of water produced is - 46 g
therefore the number of moles of water produced - 46 g / 18 g/mol = 2.56 mol
1 mol of oxygen reacts to give 2 mol of water assuming oxygen is the limiting reactant
for 2 mol of water to be produced 1 mol of oxygen has to react
therefore for 2.56 mol of water to be produced - 1/2 x 2.56 mol = 1.28 mol of oxygen should react
mass of oxygen reacted is - 1.28 mol x 32 g/mol = 41.0 g
mass of oxygen that should react is 41 g
