I believe a compound, be definition, needs to be composed of different types of atoms, so it sounds like yeah, assuming the oxygen and hydrogen atoms are actually bonded together and not just floating randomly.

A 35 L tank of oxygen is at 315 K with an internal pressure of 190 atmospheres. How
nata0808 [166]

Answer:

600.7 moles

Explanation:

Applying,

PV = nRT................... Equation 1

Where P = Pressure of oxygen, V = Volume of oxygen, n = number of moles, R = molar gas constant, T = Temperature.

make n the subject of the equation

n = PV/RT............... Equation 2

From the question,

Given: P = 190 atm, V = 35 L, T = 135 K

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

n = (190×35)/(135×0.082)

n = 600.7 moles of xygen

Write a word equation for the combustion of propane???<br> HELP????
frutty [35]

Answer:

1 mole of propane combines with 5 moles of oxygen gas to produce 3 mole of carbon dioxide and 4 moles of water.

Explanation:

The word equation for the combustion of propane can be obtained from the chemical equation;

      C₃H₈   +    5O₂    →   3CO₂   +   4H₂O  

The word equation is therefore:

 1 mole of propane combines with 5 moles of oxygen gas to produce 3 mole of carbon dioxide and 4 moles of water.

For such a combustion reaction, carbon dioxide and water are produced in the process.
