Uranium-238 has a half-life of 4.46 billion years and is often analyzed
through radiometric dating to find the ages of rocks. U-238 decays in
a series that can be summarized by the equation shown below.
238 206 4 0
92.U 82 Pb + x He+ye
How many alpha particles, x, and how many beta particles, y, are
needed to balance the nuclear equation?
Select one
X = 8: y = 6
O
X = 4, y = 16
X = 5: y = 32
O
X = 16; y = 22

um i think it might be a car?

the right answer is c i just did the question.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

explanation:

0.07 g/cm³

1.37 g/cm³
