Math that what my friend says math!!!
This equation C5H + O2 ---> CO2 + H2O has a mistake.
C5H is wrong. You missed the subscript of H.
I will do it for you assuming some subscript to show you the procedure, but you have to use the right equation to get the right balanced equation.
Assuming the tha combustion equation is C5H12 + O2 ---> CO2 + H2O
First you need to balance C, so you put a 5 before CO2 and get
C5H12 + O2 ---> 5CO2 + H2O
Now you count the hydrogens: 12 on the left and 2 on the right. So put a 6 before H2O and get:
C5H12 + O2 ---> 5CO2 + 6H2O
Now count the oxygens: 2 on the left and 16 on the right, so put an 8 on before O2:
=> C5H12 + 8O2 ---> 5CO2 + 6H2O.
You can verify that the equation is balanced
Ag+CuSO4
Silver is lower than copper in the electrochemical series and therefore would not displace it in any reaction.
Answer:
4
Explanation:
A carbon atom has 4 electrons in its outermost shell (2s^2p^2). All are unpaired (none share their orbital with another electron). So all four are anxious to pair with another electron. Once it has found 4 more electrons contributed from other atom(s), it will have 4 pairs of shared electrons.
Hydrogen has one lone electron. An atom of H is downright gleeful in sharing it's electron with elements such as carbon, C. Since carbon has 4 unpaied electrons, it will combine with 4 H atoms. At that point, cabon is sharing 4 electron pairs.
