26 grams of 2,2 dimethyl hexane( C8H16) under goes combustion. How much space would the CO2 gas occupy at 26 Celsius and 101.75 kPa?

The gas occupies a space of 5.57 L at 26 Celsius and 101.75 kPa.

Explanation:

Given: Mass = 26 g

Pressure = 101.75 kPa

Convert kPa into atm as follows.

Temperature =

Now, moles of a substance is defined as mass of substance divided by its molar mass.

As molar mass of 2,2 dimethyl hexane is 114.23 g/mol. So, its number of moles are calculated as follows.

Formula used to calculate the volume is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

Thus, we can conclude that the gas occupies a space of 5.57 L at 26 Celsius and 101.75 kPa.

i'm not sure

explanation:

i'll try whatever you got

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
