yes it is chawklit

H'okay rezz.

I have a chemistry unit test tomorrow and im cramming atm.

Before i ask this question..I WAS NEVER GOOD AT SCIENCE.

Kay..so im doing review questions and theres this question that says

Element Q is a metal with 2 valence electons, and element X is a non metal with 5 valence electrons. They combine to form an ionic compound. What is its formula?

The answer i came up with is

Element Q= Nitrogen (Cation)
Element X= Beryllium (Anion)

But this makes no sense, i've never heard of a compound made of nitrogen+beryllium...HALP.

Berrylium Nitride

Berrylium Nitride

Thats what i thought, then i wikied it and got nothing o.O (brb shower)

lolz, chem >.>
yea most is just guess and check for balancing equations, until redox equations

Did this in class today. But I was baked so

[Remuss]

Just take it step by step.

Set it up like this, well this is what always helped me.

__(NH4)3PO4 + __Pb(NO3)4 -> __Pb3(PO4)4 + __NH4NO3

# - N - #
# - H - #
# - P - #
# - O - #
# - PB - #

The left side number is your reactants, than the right side is your products. Than fill it in, than just try to get the numbers to match. It is sort of a long process but it has always worked for me.

I know how to balance chem equations thanks to everybody

I just need to know the answer for my question above

Wait no, redneck and i were right

Beryllium nitride works, as well as Magnesium nitride and Calcium nitride - all salts.

Looks like we have some good organic chemists in here. I have a problem myself:

What mechanisms and reagents should be used in synthesizing phenylacetylene from ethylbenzene? Anyone?
