Answer:
See explanation
Explanation:
When the bromine free radical attacks 2,3-dimethylbutane, two free radicals may result. One of them is primary (formed by attack on then end -CH3 group) the other is secondary.
Recall that the order of stability of free radicals is tertiary > secondary > primary > methyl.
Hence the secondary free radical is more thermodynamically stable hence it is the major free radical formed in the first propagation step.

Answer:
The statement about the nuclear envelope which is false is D - The nuclear envelope is continuos with the Golgi apparatus.
Explanation:
The nuclear envelope is composed of two membranes pierced by pores. They are distributed throughout the entire surface of the envelope and are much more than perforations in which both external and internal membranes are continued. Inside the pores a set of proteins form a structure called NPC where the smallest molecules pass, since the larger ones require energy input. The nuclear envelope that is reinforced by filaments, its two bilayers are continued with the endoplasmic reticulum membrane system.
The immediate product of neutron absorption by Ag-107 is silver atom with a mass of 108, Ag-108.
<h3>What is radioactivity?</h3>
Radioactivity is the spontaneous emission of radiation as wall as particles and energy l by the nucleus of elements due to their disintegration.
The radioactive particles that are usually emitted include:
- alpha particles
- beta particles and
- neutrons
The neutron has a mass of 1.
When silver isotope having a mass of 107 absorbs a neutron, the silver isotope produces will have a mass of 108, Ag-108.

Answer:
Hydrogen-1
Explanation:
Not sure what kind of explanation is needed for your question, because it doesnt specify.
The easiest should be:
Average mass of an element is calculated as the sum of the multiplication of each isotope by its percentage
And the mass of the hydrogen is 1, therefore the more abundant is hydrogen-1
