C8H18+ O2> CO2+ H2O how to make this balanced?

Chemistry

Sonbull [250]3 years ago
7 0
Product:
C: 1
O:3
H: 2

reactant:
C: 8
H: 18
O: 2

first you need to put probably an eight in front of the Carbon.
Next, add a coefficient of 9 to Hydrogen
finally, add a 3 INSTEAD of a 2 to Oxygen

should look like:
C8H18+O3>C8O2+H9O

If you could add an explanation that would be nice too :) thanks

First you find the atomic mass of CH2
they give you the mass so it is
12.01+ (2 x 1.008) (because there’s 2 H)
= 14.026
divide 70.13/14.026= 5
now you multiply the coefficient by 5 so
CH2 becomes C5H10
hope that helped

When the pressure that a gas exerts on a sealed container changes from 893 mm hg to 778 mm hg, the temperature changes from 49.3
solong [7]

Answer: The final temperature of the gas is 7.58 °C.

Explanation: We are given initial and final pressure of the system and we need to find the final temperature of the system.

To calculate it, we use the equation given by Gay-Lussac.

His law states that pressure is directly related to the temperature of the gas.

P\propto T

Or,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1 = initial pressure = 893 mmHg = 1.175atm (Conversion factor: 1atm = 760mmHg)

T_1 = initial temperature = 49.3°C = [49.3 + 273.15]K = 322.45K

P_2 = Final pressure = 778mmHg = 1.023atm

T_ = Final temperature = ?°C

Putting values in above equation, we get:

\frac{1.175atm}{322.45K}=\frac{1.023atm}{T_2}\\\\T_2=280.73K

Converting Final temperature from kelvin to degree Celsius.

T_2=280.73K=[280.73-273.15]^oC=7.58^oC

Hence, the final temperature of the gas is 7.58 °C.
