ANSWER: polar covalent, it is what happens when there is unequal bond between two atoms, where one has a slightly negative charge and one has a slightly positive charge.
<span>I would propose the word trigonal pyramidal or pyramidal . This is because the bond angle in ammonia ( also known as NH3) is about 107 degrees. Also please note that the number of bonding pairs of electrons in ammonia (NH3) is 3 and the Number of lone pairs of electrons in ammonia(NH3) is 1. Finally it has 8 valence electrons (5 + 3x1 = 8).</span>
Answer:
Explanation:
The reaction is:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
We see, that the equation is ballanced.
As we have data from only one reactant, we assume the other is in excess.
Ratio is 1:4 (stoichiometry). We solve this, by a rule of three:
1 mol of propane can produce 4 moles of water
Then, 4 moles of propane, may produce
( 4 . 4 ) /1 = 16 moles of water can be made.
Remember, we always have to work with the limiting reactant.
