The production of ethylene glycol from ethylene chlorohydrin and sodium bicarbonate ch2ohch2cl + nahco3 → (ch2oh)2 + nacl + co2↑ is carried out in a semibatch reactor. a 1.5-molar solution of ethylene chlorohydrin is fed at a rate of 0.1 mole/minute to 1500 dm3 of a 0.75-molar solution of sodium bicarbonate. the reaction is elementary and carried out isothermally at 30°c where the specific reaction rate is 5.1 dm3/mol/h. higher temperatures produce unwanted side reactions. the reactor can hold a maximum of 2500 dm3 of liquid. assume constant density. (a) plot and analyze the conversion, reaction rate, concentration of reactants and products, and number of moles of glycol formed as a function of time.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

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.
