<h3>What is butane ?</h3>
One of the smallest liquid streams frequently created in a refinery is butane. Ten hydrogen atoms and four carbon atoms make up the butane molecule. Typically, butane is either marketed as a finished product or is blended into LPG or gasoline in tiny quantities.
It is frequently employed as a fuel for portable stoves and cigarette lighters, as a propellant in aerosols, as a heating fuel, as a refrigerant, and in the production of a broad variety of goods. Liquefied petroleum gas and butane both exist (LPG).
Butane has a low level of toxicity. In butane misuse, high exposure concentrations can be anticipated. Central nervous system (CNS) and cardiac consequences are the most frequently seen effects in cases of misuse.

The pressure of diver = atmospheric pressure + water pressure
atmospheric pressure = 750 mmHg (as given) = 750 / 760 atm = 0.987 atm
Water pressure is
P = hρg
where
h = height of water = 38 ft
1 ft = 0.3048
38 ft = 11.58 m
ρ = density = 1000 Kg / m³
g = gravitational constant = 9.81 m/s2
P = 11.58 X 1000 X 9.81 = 113599.8 Kg / m s^2 Or N /m^2
1 N / m^2 = 1 pa = 9.869 X 10^-6 atm
P = 113599.8 Pa = 1.12 atm
Total pressure = 1.12 + 0.987 atm = 2.107 atm = 2.1 atm (two significant figures)
Aluminum has three electrons in its valence shell. if you look at the periodic table, there are numbers at the top. in column 2, the elements have 2 valence electrons, in column 3 they have 3 valence electrons etc.
