How many moles of phosphine (PH3) are produced for every 4.0 moles of hydrogen that react according to the chemical equation bel

Mariana [72]

Answer: 2.67 moles of Phosphine are produced

Explanation:

From the equation 3H2 + P2 → 2PH3

3 moles of hydrogen (H2) = 2 moles of Phosphine (PH3)

4 moles of hydrogen = X moles of PH3

Then, cross multiply

X moles of Phosphine = (4 x 2) / 3

= 8 / 3

= 2.67 moles

Thus, 4 moles of hydrogen produces 2.67 moles of Phosphine

Which of the following isotopes would most likely be unstable and therefore radioactive?

svlad2 [7]

Answer: Mercury-194 is an unstable isotope and hence is radioactive.

Explanation: Mercury-194 is an isotope of mercury, having formula $_{80}^{194}\textrm{Hg}$

Number of protons in this isotope = 80

Number of neutrons in this isotope = 114

This isotope is radioactive in nature and under decay process by Electron Capture.

Electron capture reactions are the reactions in which a proton in a nucleus absorbs an electron and convert it into neutron. The resulting nucleus will have a decreased atomic number and same atomic mass.

Reaction for electron capture of mercury-194 follows:

$_{80}^{194}\textrm{Hg}+_{-1}^0\textrm{e}\rightarrow _{79}^{194}\textrm{Au}$
