A sample of well water is tested and found to have 1350 ppm Iron. If a 1000g sample was tested, how many grams of iron were in i

ppm is parts per million, and is usually done by weight.

So, 1000g, times (1350/1000000) = 1.350g iron.

Two moles of ideal He gas are contained at a pressure of 1 atm and a temperature of 300 K. 34166 J of heat are transferred to th

iragen [17]

Explanation:

The given data is as follows.

n = 2 mol, P = 1 atm, T = 300 K

Q = +34166 J, W= -1216 J (work done against surrounding)

$C_{v}$ = $\frac{3R}{2}$

Relation between internal energy, work and heat is as follows.

Change in internal energy ( $\Delta U$ ) = Q + W

= [34166 + (-1216)] J

= 32950 J

Also, $\Delta U = n \times C_{v} \times \Delta T$

= $3R \times (T_{2} - T_{1})$

32950 J = $3 \times 8.314 J/mol K \times (T_{2} - 300 K)$

$\frac{32950}{24.942} = T_{2} - 300 K$

1321.06 K + 300 K = $T_{2}$

$T_{2}$ = 1621.06 K

Thus, we can conclude that the final temperature of the gas is 1621.06 K.

What did J.J. Thomson discover about the atom that changed the atomic model previously used?

galina1969 [7]

J.J. Thomson hypothesized and discovered that the atom was not the smallest unit of matter but that instead there were much smaller units. He discovered "sub-atomic particles" which make up atoms. The sub-atomic particle that Thomson discovered was the electron. He discovered this through a process of experiments testing cathode rays.
