Answer:

Neutron radiation

Explanation:

Neutron radiation is a form of ionizing radiation that presents as free neutrons. Typical phenomena are nuclear fission or nuclear fusion causing the release of free neutrons, which then react with nuclei of other atoms to form new isotopes—which, in turn, may trigger further neutron radiation.

Determine the pH of a 0.015 M HNO3 solution.
miskamm [114]

Answer:

0.015 M HNO3 = 0.015 M H3O+ pH = -log(0.015) = 1.82 [OH -] = 1.0 x 10 -14/0.015 M = 6.7 x 10 13 Check: HNO3 is a strong acid, so we expect the pH to be low and the [OH ] to be small

A rigid tank is divided into two equal volumes. One side contains 2 kmol of nitrogen N2 at 500 kPa while the other side contains
k0ka [10]

Answer:

The partial pressure of the CO_2 in the final mixture is 200 kPa.

Explanation:

Pressure of nitrogen gas when the two tanks are disconnected = 500 kPa

Pressure of the carbon-dioxide gas when the two tanks are disconnected = 200 kPa

Moles of nitrogen gas =n_1= 2 kmol

Moles of carbon dioxide gas =n_2=8 kmol

After connecting both the tanks:

The total pressure of the both gasses in the tank = p = 250 kPa

According to Dalton' law of partial pressure:

Total pressure is equal to sum of partial pressures of all the gases

Partial pressure of nitrogen =p_{N_2}^o

Partial pressure of carbon dioxide=p_{CO_2}^o

p_{N_2}^o=p\times \frac{n_1}{n_1+n_2}

p_{N_2}^o=250 kPa\times \frac{0.2}{0.2+0.8}=50 kPa

p_{CO_2}^o=p\times \frac{n_2}{n_1+n_2}

p_{CO_2}^o=250 kPa\times \frac{0.8}{0.2+0.8}=200 kPa

The partial pressure of the CO_2 in the final mixture is 200 kPa.
