3. The dehydration of sugar (sucrose) can be represented by the following balanced chemical equation.
C12H22O11(s) → 12 C(s) + 11 H2O(g)
Predict the chemical amount (moles) of carbon and water vapor produced by the dehydration of
15.0 mol of sucrose. (2 marks)

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

the answer is c. nacl

i think that the answer is c
