Answer:
The hydrogen molecules combine with the oxygen molecules, 2 hydrogen molecules, and 1 oxygen molecules is the amount needed to make one water atom or molecule, whatever you want to call it.
<span> this represents the relative overall energy of each orbital, and the energy of each orbital increases as the distance from the nucleus increases</span>
The volume of the sample of propane at STP is 0.62 mL.
<h3>What is volume?</h3>
Volume is the amount of space that a substance or object occupies.
To calculate the volume of gas at STP, we apply the formula below.
Formula:
- PV/T = P'V'/T'................. Equation 1
Where:
- P = Initial pressure of gas
- V = Initial volume of gas
- T = Initial temperature of gas
- P' = Standard pressure (SP)
- T' = Standard temperature (ST)
- V' = Volume of gas at STP.
Make V' The subject of the equation
- V' = PVT'/P'T.............. Equation 2
From the question,
Given:
- P = 320 torr
- V = 1.73 mL
- T = 30 °C = (30+273) K = 303 K
- P' = 760 torr
- T' = 273 K
Substitute these values into equation 2
- V' = (320×1.73×273)/(760×303)
- V' = 0.62 mL
Hence, the volume of the sample of propane at STP is 0.62 mL.

It is in orbit around the Sun.
It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape).
It has “cleared the neighborhood” around its orbit.
