Give the number of protons, neutrons and electrons in 99Tc
miss Akunina [59]

Explanation:

Tc - 99 is technetium 99.

It is a radioactive element that decays spontaneously. It has a half-life of 211,000 years and decays to stable ruthenium.

  • On the periodic table, it has an atomic number of 43;

Mass number  = 99

Atomic number = number of protons = number of electrons in atom

  Number of protons in Tc is 43

                      electron is 43

Mass number = number of protons + number of neutrons

  Number of neutrons = mass number - number of protons = 99-43 = 56

Help please. 15.0 moles of gas are in a 3.00L tank at 23.4∘C . Calculate the difference in pressure between methane and an ideal
CaHeK987 [17]
Using PV=nRT or the ideal gas equation, we substitute n= 15.0 moles of gas, V= 3.00L, R equal to 0.0821 L atm/ mol K and T= 296.55 K and get P equal to 121.73 atm. The Van der waals equation is (P + n^2a/V^2)*(V-nb) = nRT.  Substituting  a=2.300L2⋅atm/mol2 and b=0.0430 L/mol, P is equal to 97.57 atm. The difference is <span>121.73 atm- 97.57 atm equal to 24.16 atm.</span>

Give an example of a solution that can be seperated by simple distilation.​
Juliette [100K]

Answer: Evaporation of salt water

Explanation: During the process of evaporating salt water which involves simple distillation, pure water is separated with salt molecules.

When heated water evaporates from the solution since it is less dense. When condensed it becomes pure water and salt is left out since it is more denser.
