<u>Answer:</u> The molarity of solution is 0.34 M.
<u>Explanation:</u>
- To calculate the number of moles, we use the equation:
<u>For lead chloride:</u>
Given mass of lead chloride = 18.86 g
Molar mass of lead chloride = 278.1 g/mol
Putting values in above equation, we get:
- For the balanced chemical equation:
By Stoichiometry of the reaction:
1 mole of lead chloride is formed by 1 mole of lead nitrate
So, 0.068 moles of lead chloride will be formed from = of lead nitrate
- To calculate the molarity of solution, we use the equation:
We are given:
Volume of solution = 200 mL = 0.200 L (Conversion factor: 1 L = 1000 mL)
Moles of lead nitrate = 0.068 moles
Putting values in above equation, we get:
Hence, the molarity of solution is 0.34 M.
I believe it is spontaneous generation
Answer:
When a large, fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron, it may undergo nuclear fission. The nucleus splits into two or more lighter nuclei, releasing kinetic energy, gamma radiation, and free neutrons.

Explanation:
The addition of a halohydrin to an alkene proceeds via the bromium cyclic intermediate.
The bromine dissociates heterolytically and attacks the (E)-2-hexene yielding the brominuim ion intermediate. This is now attacked by water with a consequent loss of H^+ to yield the final product.
Since the reaction involves a flat and planar carbocation intermediate, racemization is possible, thereby leading to the two stereoisomers shown in the image attached to this answer.
