A nutty question. Let's look at each answer.
1. That unbalances. H is not balanced. O is not balanced.
2. Obviously not an good answer. Still unbalanced.
3. Still unbalanced. Both C and H balanced.
4. must be right since the other possibilities are not correct. You have added 1 O2 so that will be left over.
CH4 + 2O2 → CO2 + 2H2O
If you change the 2 in front of 2O2 to a 3, what will be the change in the results on the right side of the equation?
There are now 3H2O molecules. <- ?
Nothing changes in the equation.
There are now 3CO2 molecules. <- ?
There is an extra O2 molecule left over.

1. There is an extra O2 molecule left over.
2. Covalent bonds tend to be less polar than ionic bonds.
3. PH3
4. replacement
5. Each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon atom.
6. H2SO4 + 8HI → H2S + 4I2 + 4H2O
7. 2, 1, 2
8. Nitrogen and oxygen have an electronegativity difference of 0.5, so the bond is polar covalent, with oxygen pulling the electrons toward it.
9. Sodium donates an electron to chlorine.
10. selenium (Se)
11. bond type
12. six
13. K
14. indicator
the rest are essay questions sorry :/

U took the test and you're sure these are correct right?
yes, he’s correct. just took the test.
Yessirrr they are correct
Thank youuuuuu
still correct
my guy is a spooky potato
potato is not sus
Does anyone know the essay questions?
Thank you Mr. Sus Potato...!
@potato is 100% correct

The bonding activity that occurs between phosphorus and chlorine is Covalent Bonding
Covalent bonding is an interaction between two atomic elements that share electrons between themselves.
In Phosphorus Pentachlorine PCl₅, covalent bonding occurs between Phosphorus and Chlorine.
This is because, Phosphorus is the central atom that is attached to 5 different chlorine atoms, each chlorine atom needs one electron each to complete its octet rule and since phosphorus has five valence electrons in its outermost shell, it shares it with each of the chlorine atoms.

Me: "NAAAH, POTATO U GUD U a life saver anyway"
He's 100% correct, B-T-dubs.
