Uranium-238 is an unstable nuclide that emits an alpha particle, three neutrons, and gamma particles. A = 231 and Z = 90. What daughter nuclide is formed from this reaction? Question 9 options: A) Th B) Fr C) Pu D) Ra HURRyYYYyyy

First we calculate the number of moles of sugar (which I assume is sucrose). number of moles = mass / molecular weight number of moles of sugar = 19 / 342 = 0.055 moles Now we may calculate the molarity of the solution. molarity = number of moles / solution volume (L) molarity = 0.055 / 0.05 = 1.1 M

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

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.
