A sample of 1.00 moles of oxygen at 50°C and 98.6 kPa occupies a volume

Chemistry
1 answer:
Kryger [21]3 years ago
5 0

Answer:

27.22dm³

Explanation:

Given parameters:

number of moles = 1 mole

temperature  = 50°C, in K gives 50+273 =323K

Pressure  = 98.6kpa in atm, gives 0.973atm

Unknown:

Volume of the gas = ?

Solution:

Since the unknown is the volume of gas, applying the ideal gas law will be appropriate in solving this problem.

The ideal gas law is mathematically expressed as;

            Pv = nRT

where P is the pressure of the gas

          V is the volume

          n is the number of moles

          R is the gas constant

         T is the temperature

Input the parameters and solve for V;

                    0.973 x V  = 1 x 0.082 x 323

                           V  = 27.22dm³

Suppose an aluminum- nuclide transforms into a phosphorus- nuclide by absorbing an alpha particle and emitting a neutron. Comple
AfilCa [17]

Explanation:

An alpha particles is basically a helium nucleus and it contains 2 protons and 2 neutrons.  

Symbol of an alpha particle is ^{4}_{2}\alpha. Whereas a neutron is represented by a symbol ^{1}_{0}n, that is, it has zero protons and only 1 neutron.

Therefore, reaction equation when an aluminum- nuclide transforms into a phosphorus- nuclide by absorbing an alpha particle and emitting a neutron is as follows.

        ^{27}_{13}Al + ^{1}_{0}n \rightarrow ^{30}_{15}P + ^{1}_{0}n
