Answer:
Ethane
Explanation:
CH3-CH3 is an alkane by the name of ethane. In organic chemistry there is a systematic way of naming compounds according to the prefix (eth) and the suffix (ane.)
The prefixes vary according to the number of carbon atoms:
1 C = meth
2 C = eth
3 C = prop
4 C = but
Answer: Sulfur
Explanation: Sulfur has 16 protons, silicon has 14 protons, and gold has 79 protons.
Answer:
Explanation:
The gas ideal law is
PV= nRT (equation 1)
Where:
P = pressure
R = gas constant
T = temperature
n= moles of substance
V = volume
Working with equation 1 we can get

The number of moles is mass (m) / molecular weight (mw). Replacing this value in the equation we get.
or
(equation 2)
The cylindrical container has a constant pressure p
The volume is the volume of a cylinder this is

Where:
r = radius
h = height
(pi) = number pi (3.1415)
This cylinder has a radius, r and height, h so the volume is 
Since the temperatures has linear distribution, we can say that the temperature in the cylinder is the average between the temperature in the top and in the bottom of the cylinder. This is:
Replacing these values in the equation 2 we get:
(equation 2)
