What is the atomic number of pt-175 after it undergoes alpha decay

Chemistry
1 answer:
DanielleElmas [232]3 years ago
5 0

Answer:

76

Explanation:

Alpha decay is one of the most basic forms of radioactive decay. It has an atomic mass of 4 and a proton number of two.

Undergoing an alpha decay will decrease the atomic mass by four and the atomic number by two.

In this particular question, we are particular about the atomic number. The atom has an atomic number of 78. So taking 2 off this gives 76

Klio2033 [76]

The peaks at 3300 cm-1 and 2200 cm-1 are due to terminal alkyne group (triple bond between two carbons) and triple bonded C-H stretching

So

The answer is : terminal alkyne

Another peak near 3430 cm-1 must be due to an -OH group

so the answer is : alcohol

Convert 150 kPa to atmospheres. *
lakkis [162]

Answer: 1.48 atmosphere

Explanation:

Pressure in kilopascal = 150

Pressure in atmosphere = ?

Recall that 1 atmosphere = 101.325 kilopascal

Hence, 1 atm = 101.325 kPa

Z atm = 150 kPa

To get the value of Z, cross multiply

150 kPa x 1 atm = 101.325 kPa x Z

150 kPa•atm = 101.325 kPa•Z

Divide both sides by 101.325 kPa

150 kPa•atm/101.325 kPa = 101.325 kPa•Z/101.325 kPa

1.48 atm = Z

Thus, 150 kPa is equivalent to 1.48 atmospheres
