Answer:

A heat exchanger is device which is designed to transfer heat from one matter to another. In nuclear power plants, these heat exchangers are used to pass heat from primary system to the secondary system. In the process they produce steam from water, they are also called steam generators or pressurized water reactors.

What is the mass in milligrams of 4.30 moles of sodium?use âeâ for âÃ10" and use significant figures?

Elis [28]

First, calculate the mass of sodium in g with the help of molar mass and number of moles.

Number of moles = $\frac{given mass in g}{molar mass}$ (1)

Molar mass of sodium = $23 .0 g/mol$

Substitute the given value of number of moles and molar mass of sodium in formula (1)

$4.30 moles = \frac{given mass in g}{23.0 g/mol}$ (1)

$4.30 moles\times 23.0 g/mol = mass in g$ (1)

mass of sodium in g = $98.9 g$

Now, according to conversion factor, 1 g = 1000 mg

So, $98.9 g$ of sodium = $98.9 \times 1000 mg$

= $98900 mg$ of sodium

Thus, mass of sodium in mg = $9.89 \times 10^{4} mg$

How is condensation explained by the Kinetic Molecular Theory? Cooling reduces particle motion, resulting in coalescence by attr

lara31 [8.8K]

Temperature means, in this context, movement.

Condensation can be explained by the reduction of temperature of the system. This effect make possible the cohesion forces increases. In other words, the result is coalescence by attractive forces.
