Explanation:

energy: power derived from the utilization of physical or chemical resources

kenetic energy: energy which a body possesses by virtue of being in motion

potential energy: the energy possessed by a body by virtue of its position relative to others

work: forced multiples distance

mechanical energy: energy of an object due to its motion or position; the sum of an objects kenetic energy and potential energy

sound energy: movement of energy through a substance

thermal energy: refers to energy contained within a system that is responsible for its temperature

electric energy: energy (both kinetic and potential) in the changed particles of an atom that can be used to apply force and/or do work

radiant energy: energy that travels by waves or particles

nuclear energy: energy in the nucleus, or core, of an atom

3. A student adds 0.400g of n-propanol to 13.0 g of t-butanol. What is the molality of the solution? Show your calculations. (3

Answer:

$m=0.512m$

Explanation:

Hello,

In this case, we can consider the n-propanol as the solute (lower amount) and the t-butanol as the solvent (higher amount), for which, initially, we must compute the moles of n-propanol (molar mass = 60.1 g/mol) as shown below:

$n_{solute}=0.400g*\frac{1mol}{60.1g0}=6.656x10^{-3}mol$

Since the molality is computed via:

$m=\frac{n_{solute}}{m_{solvent}}$

Whereas the mass of the solvent is used in kilograms (0.0130g for the given one). Thus, we compute the resulting molality of the solution:

$m=\frac{6.656x10^{-3}mol}{0.0130kg}\\ \\m=0.512\frac{mol}{kg}$

Or just:

$m=0.512m$

Best regards.

An element initially weighed 3.555 g. When it was burned in oxygen an oxide compound was produced. The product mass was 4.666 g.

lesya692 [45]

A)
The additional mass is that of Oxygen
4.666 - 3.555
= 1.111 g
B)
The percentage mass of oxygen can be obtained by:
[(mass of Oxygen)/ (Total mass of product)] * 100
= (1.111 / 4.666) * 100
= 23.81%
