Answer:
⁹⁶₄₂Mo + ²₁H ⇒ ⁹⁸₄₃Tc
Explanation:
During the bombardment of a molybdenum target with deuterium ions, an element not found in nature was produced.The name of the element formed in the process is technetium. It is an element with the symbol Tc, mass number of 98, and atomic number 43. The nuclear equation is shown below:
⁹⁶₄₂Mo + ²₁H ⇒ ⁹⁸₄₃Tc
Technetium is the lightest element whose isotopes are all radioactive in nature except the fully ionized state of isotope ⁹⁷Tc. It is silvery gray in color and can be found between manganese and rhenium in group seven of the periodic table.

Answer:
Molarity of 
solution is 0.612 mol/L
Explanation:
Number of moles of a substance = (mass of substance)/(molar mass of the substance)
Molar mass of = 214 g/mol
So, 562 g of = 
moles of = 2.63 moles of
Molarity of a solution = (number of moles of solute in solution)/(total volume of solution in liter)
Here solute is and solvent is water
Total volume of solution is 4.30 L
So, molarity of solution = 
= 0.612 mol/L
AT, STP in chemistry is the abbreviation for Standard Temperature and Pressure. STP most commonly is used when performing calculations on gases, such as gas density
