wolverine [178]3 years ago
5 0

Answer:

heated crude oil enters a tall fractionating column , which is hot at the bottom and gets cooler towards the top. vapours from the oil rise through the column. vapours condense when they become cool enough. liquids are led out of the column at different heights.

Water wheels convert the kinetic energy of moving water into which form? A. potential energy B. chemical energy C. gravitational
denpristay [2]

Answer:

the answer is mechanical energy

Explanation:

A water wheel converts the kinetic energy of moving or falling water into mechanical energy. This mechanical energy is used for powering the mill.Water wheels have wooden or metal wheels that have buckets or blades attached around them. They are placed in a river or lake. The force of the water rotates the wheel. As the wheel moves, it turns an axle attached horizontally to the wheel. The axle in turn moves the system of gears that operate the functioning of mills. Waterwheels were used for preparing fiber and crushing ore.

Where would the temperature of the ocean's surface water be the lowest?
bazaltina [42]

Answer:

The correct answer is option C, areas with a high salinity

Explanation:

The higher the density of the ocean water, the lower will be the temperature. The highly saline ocean water thus exists in the polar regions than the tropic regions. Due to high density the cold water seeps down and thus it further becomes cooler while a low density ocean water remains at the surface and possess additional heat

Given the problem below, what would the first step be in solving it?
Hoochie [10]

Answer:

First step would be convert to moles

Final Answer: 37.8 g of NaCl

Explanation:

The reaction is:

2Na + Cl₂ → 2NaCI

We convert the mass of each reactant to moles:

18 g . 1mol /23g = 0.783 moles of Na

23g . 1mol / 70.9g = 0.324 moles of chlorine

We use the mole ratio to determine the limiting reactant:

Ratio is 2:1. 2 moles of Na react to 1 mol of chlorine

Then, 0.783 moles of Na, may react to (0.783 . 1)/2 = 0.391 moles.

Excellent!. We need 0.391 moles of Cl₂ and we only have 0.324 moles available. That's why the Cl₂ is our limiting reactant.

We use the mole ratio again, with the product side. (1:2)

1 mol of Cl₂ can produce 2 moles of NaCl

Then, our 0.324 moles of gas, may produce (0.324 . 2)/1 = 0.648 moles

Finally, we convert the moles to grams:

0.648 mol . 58.45g/mol =
