Explanation:
Hello.
In this case, given the volume (1cm³=1mL) and density of the bromine we are to firstly compute the mass since it will allow us to compute the representative particles:
Next, since the mass of one mole of diatomic bromine is 159.82 g (one bromine weights 78.91), we can next compute the moles in that sample:
Finally, via the Avogadro's number we can compute the representative particles of bromine as follows:
Best regards.
Answer: Option (c) is the correct answer.
Explanation:
It is known that when Gibb's free energy, that is, 
has a negative value then the reaction will be spontaneous and the formation of products is favored more rapidly.
Activation energy is defined as the minimum amount of energy required to initiate a chemical reaction.
So, when reactants of a chemical reaction are unable to reach towards its activation energy then a catalyst is added to lower the activation energy barrier so the reaction can take place rapidly.
Since, the given reaction has low activation energy. Therefore, there is no need to add a catalyst.
And, when value of is positive then the reaction is spontaneous in nature and formation of products is less favored.
Thus, we can conclude that for the given situation positive delta G is the reason that a reaction might form products very slowly, or not at all.
Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.

But all in all, the cells have different structures and different jobs. This means that they are produced for that one job and cannot be made to do another job that they aren’t specifically made for. As well the dna make up will produce these cells specifically and in different cells than the other.
Hopefully this helps some. Have a nice day!
To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.
Hope this helps :)
