A because A is the only answer
Given that <span>sample a has a higher melting point than sample
b. Therefore, sample a is a longer chain of a </span><span>fatlike solid substance. It could also be that the bonds present in sample a is much stronger which will require more energy to break. Hope this answers the question.</span>
Answer:
Muscle cell
Explanation:
An example of a specialized cell would be a muscle cell, which allows muscles to contract. A specialized cell has a specific function.
Arguably A, B and C are all correct. Atoms of elements can form compounds such as NaCl(table salt). Molecules form molecular compounds and minerals are just complex molecule compounds.
Moles =mass/ molar mass of the bromine atom
the molar mass of bromine atom is 79.904g/mol
mass=2.60 x10^2
therefore the moles of bromine atom=
2.60 x10^2g/ 79.904g/mol =3.25gmoles(answer 4)
