Which type of nuclear decay is the radioactive isotope fe2659 likely to undergo?
jekas [21]

Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.

Whenever there are too many protons or even neutrons in a nucleus, one of the protons and neutrons will turn into the other, which is known as beta decay. During beta minus decay, a neutron transforms into a proton, electron, as well as antineutrino.

Fe_{26} ^{59} → Co_{27} ^{59} +\beta_{1}  ^{0}

It can be seen that after the beta minus decay Fe changes into Co.

In beta decay , decrease in atomic number by one unit Fe atom get converted into Co atom.

Neutron-rich nuclei often decay by producing both an electron and an antineutrino.

Therefore, Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.

The Molar Mass (g/mol) of an ideal gas whose density is 2.5g/L at 1.8 atm and 30,0 Celsius ?
tia_tia [17]

Answer:

M = 35 g/mol

Explanation:

Given data:

Density = 2.5 g/L

Pressure = 1.8 atm

Temperature = 30°C (273.15 +30 = 303.15 K)

Molar mass = ?

Solution:

d = PM/RT

M = dRT/P

M =  2.5 g/L × 0.0821 atm.L/mol.K ×  303.15 K / 1.8 atm

M = 62.22 atm. g/mol/ 1.8 atm

M = 35 g/mol

Which type of rock is most likely to form because of high heat and pressure?
NikAS [45]

Answer:

<h2>Metamorphic</h2>

Explanation:

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
