Answer: Option (b) is the correct answer.

Explanation:

Atomic mass means the sum of total number of protons and neutrons present in an atom. On the other hand, atomic number is only the sum of total number of protons present in an atom.

Generally, when we write symbol of a neutral element denoting its atomic mass and number then atomic mass is placed on the top left corner and atomic number is written on the bottom left corner.

For example, ^{19}_{9}F shows atomic mass of fluorine is 19 and its atomic number is 9.

Thus, we can conclude that atomic mass is determined by the number of protons plus the number of neutrons.

I would believe that the answer is B. Neutrons
Electrons don't have any mass
Charges and atoms don't even make sense in this question

Reaction intermediates differ from activated complexes in that A. they are stable molecules with normal bonds and are frequently
vova2212 [387]

Answer:

they are molecules with normal bonds rather than partial bonds and can occasionally be isolated.

Explanation:

In chemistry, reaction intermediates are species that are formed from reactants and are subsequently being transformed into products as the reaction progresses. In other words,  reaction intermediates are species that do not appear in a balanced reaction equation but occur somewhere along the reaction mechanism of a non-elementary reaction. They are usually short lived species that possess a high amount of energy. They may or may not be isolated.

They are often molecular species with normal bonds unlike activated complexes that are sometimes hypervalent species.

if the theoretical yield of a reaction is 26.0 grams and you actually recovered 22.0 grams what is the precent yield
netineya [11]
Percentage Yield = (Actual Yield ÷ Theoretical Yield) × 100  

∴ if theoretical yield is 26 g, but only 22.0 is recovered from the reaction, 
then Percentage Yield = (22 g ÷ 26 g) × 100  
                                       =  84.6 %
