determine the mass of carbon iv oxide produced on burning 104g of ethyne C2H2

11 answers

mass carbon in 104g : 24/28 * 104=89.1 grams
moles C=89.1/12=7.42 moles
the product is CO2, so mass of 7.42 moles CO2=7.42*44=...
Determine the mass of carbon(iv)oxide produced on burning 104g of ethane (c2 H2 )
C= 12, h= 1, o=16.
2(2 H2 + 502 4 co2 +2H2 0
12×2+1 ×2 4 ×(12+16 ×2)
26g 176g
Amount = molar mass.
104/26 =4 mols.of ethane
2mol c2 H2 4
4 mol 11=@
x=(4 ×4)/2 =8 mole co2
Determine the mass of carbon(iv)oxide produced on burning 104g of ethane (c2 H2 )
C= 12, h= 1, o=16.
2(2 H2 + 502 4 co2 +2H2 0
12×2+1 ×2 4 ×(12+16 ×2)
26g 176g
Amount = molar mass.
104/26 =4 mols.of ethane
2mol c2 H2 4
4 mol 11=x
x=(4 ×4)/2 =8 mole co2
how do you get that 26g
How do you get it, it isn't clear
Even the answer is wrong don't mind them they don't know anything
From the equation:
2C2h2(g)+5O2(g)-4co2(g)+2H2O(g)
Molar mass: 2c2h2 4co2
26 44
2mol 4mole
Amount of c2h2 reacted=n=m/M
n=molar mass/reacting mass
n=104/26=4 moles
2 moles of c2h2 gives 4moles of co2
4 moles of c2h2 produces:
2-----------4
4-----------x
2x=4*4
2x=16
x=8 moles of co2
8*44=352 g of co2
So 352g of co2 is produced on burning 104g of c2h2
It isn't clear explain more
Even the answer is wrong, dont might them
determine the mass of carbon (iv) oxid

e, Co2 produced on burning 104g of ethyne, C2H2 (C=12, 0=16, H=1)
I did not get the answer
