Answer
The matching is numbered and represented in red arrowsi n the diagram below:
Explanation
In a steam turbine electricity generation, the mechanical energy in form of pressure present in steam is extracted and converted into kinetic energy by allowing the steam to flow through the stationary blades. This kinetic energy is transmitted to the moving blades connected to the alternator of a steam turbine generator.
The matching of the process is shown below:
Answer:
.137 moles
Explanation:
need to know the molar mass of water which is 18.01528 g/mol
2.46 g of H₂O divided 18.01528 g/mol molar mass H₂O = moles of H₂O
2.46 divided by 18.01528 =
.137 moles
C4H10 is butane
butane is commonly used in cigarette lighters
2C4H10+1302 -> 8CO2 + 10H₂O is the burning of butane
burning butane with oxygen makes carbon dioxide and water

The pressure that will be exerted if four sample of gas are placed in a single 3.5 container is calculated as below
if each gas occupies 675 mmhg
what about 4 gases in the sample
by cross multiplication
= 675 mm hg x 4/1 = 2.7 x10^3mmhg (answer D)
