consider the equation:

4ai+3o2 2ai2o3

is the equation balanced? why or why not?

If it is already balanced because the compounds aluminum(Al) and oxygen(O) have the same number of atoms

unbalanced

Explanation:

Oops I'm sorry, a year late haha. Anyway this is definitely unbalanced.

So if you write this out, you could write it as 4 A, 1 I, + 3O (x2) ---> 2 A, 1 I, 2O (x3).

so 4AI+6O---> 2AI6O

On the left there is 4AI whereas the right has 2AI. They aren't equal nor balanced.

I'm not completely sure but I hope this helps :)

(oh and tell me if I'm wrong I can change my answer)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
