I still don't get it, can u explain???
The equation is given balanced, in the link I gave, in reactions. Aluminum carbide and water yield methane and aluminum hydroxide. There is little to explain.
for the 3CH4. why is it $ and does C have to go before H??
I don't know what $ means in relation to this problem. If you meant to type 4, it is 4 because C is in column IV (or 14 depending upon the system your prof is using) which means it has an oxidation (valence) of 4. H is valence of 1 so the formula for methane is CH4. Must the C come first? Could we write as H4C. Written as H4C, CH4, or H2CH2, most will decipher that as CH4 which means methane. USUALLY, the more postive atom is placed first, which is why we write it CH4.
oh i got it:) thanks:)
