Answer:
an object that is at rest will stay at rest inless a force acts upon it.
An oject that is in motion will not change its velocity unless a force acts upon it.
8 because atomic number is the same as number of protons, protons and electrons have the same amount so that the element is neither positive nor negative.
The ratio of reactants is chlorination of <u>2,3</u> dimethyl butane the possibility of obtaining do and the polychlorinated product is not seen.
When a mixture of methane and chlorine is exposed to ultraviolet light a substitution reaction occurs and the organic product is chloromethane. Because there are various hydrogen atoms that can be extracted in the first propagation step.
Abstraction of a hydrogen atom from the middle carbon of propane results in 2-chloropropane. In the presence of sunlight, methane reacts with chlorine to form chloromethane. The chlorination of methane is a free radical substitution reaction. Chlorine cannot turn into free radicals in the dark, so no reaction takes place. Therefore, the presence of sunlight is essential for the reaction to proceed.

The answer is 264.12
The element is Bh (Bohrium). If the ion has a 1 charge, the charge can either be 1+ or 1-. So the ion has to be an element with the atomic number 107 or 109 (Bh or Mt). Using simple math, subtract the atomic number from the mass number to equal 157.
264 - 107 = 157
