What atom has the same number of neutrons as 9^B

answer:

¹⁰B has the same number of neutrons as ⁹Be

Explanation:

¹⁰B has the same number of neutrons as ⁹Be

Mass number of ⁹Be = 9

Atomic number of ⁹Be = 4

Number of neutrons of ⁹Be = mass number - atomic number

= 9 - 4 = 5

Mass number of ¹⁰B = 10

Atomic number of ¹⁰B= 5

Number of neutrons of ¹⁰B= mass number - atomic number

=10 - 5 = 5

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
