Answer:
The answer viruses, just took the test
Explanation:
D is the correct answer is sure
The first step Niven has to do
in his calculation is to Balanced the chemical equation. The answer is letter
A. The key in the balancing of chemical reaction is to make sure that you got
the exact chemical formula of the substance that is reacting and the yielded
product. After getting the formula, identify first the hardest element/atom to
be balanced such as Na, Zn, Cl, etc. Then proceed to the easier ones such as O,
H. Make sure to not the atoms present in the molecule of the substance.
Answer:
Explanation:
Hello,
In this case, by knowing that the used NaOH equals in moles the acid (monoprotic) as shown below, during the titration:
By knowing the volume and the concentration of the NaOH, one obtains:
Thus, the molar mass of the acid is computed based on the previously computed moles and the given mass as follows:
Best regards.
The first one is the answer
isotopes of an atom have different number of neutrons . the number of protons are not different in isotopes of an atom
