Answer:
The daughter nuclide is selenium; 76:34 Se
Explanation:
The complete question is as follows;
is desired to determine the concentration of arsenic in a lake sediment sample by means of neutron activation analysis. The nuclide 75:33 As captures a neutron to form 76:33 As, which in turn undergoes beta decay. The daughter nuclide produces the characteristic gamma rays used for the analysis. What is the daughter nuclide?
solution:

Water donates a proton in the forward reaction and H2C03 donates a proton in the reverse.
The answer on plato is c
Just observing an physical property of a substance cant not change the substances identity. You can only figure out its identity through test and the figuring out of the elements! I hope I was of some help!!
The partial pressure of argon in the atmosphere when the atmospheric pressure is 775. 0 torr is 7.75 torr.
Each gas that makes up a mixture of gases has a partial pressure, which represents the notional pressure of that gas if it were to occupy the entire volume of the initial mixture by itself at the same temperature.
The force that the weight of the atmosphere exerts on a certain area is known as atmospheric pressure.
As we know,
partial pressure is calculated as:
partial pressure = (total absolute pressure) × (volume fraction of gas component)
partial pressure = × 0.010
partial pressure = 775.0 × 0.010
partial pressure = 7.75 torr
Therefore, partial pressure of argon in the atmosphere when the atmospheric pressure is 775. 0 torr is 7.75 torr.
