Answer:The distribution of electrons in an atom is called as Electronic Configuration. Formula 2n2 helps in the determination of the maximum number of electrons present in an orbit, here n= orbit number.

Answer:
The answer to your question is a) pure substance- compound
Explanation:
a) pure substance-compound. A pure substance can be an element or compound that is not mixed with another substance, glucose is a compound and also a pure substance.
b) mixture-heterogeneous. This option is wrong because glucose is not mixed with another substance.
c) pure substance-element. Glucose is a pure substance but it is a compound because it is composed of carbon, hydrogen, and oxygen. This option is incorrect.
d) mixture-homogeneous. Glucose is not a mixture, it is a pure substance. This option is wrong.
e) none of the above. This option is wrong because the first option is correct.
To find the number of moles from a mass given, simply look to the formula n (moles) = m (mass, g) / MM (molar mass).
Mass was given, 36.04
Molar mass is the total atomic mass of all the atoms present. Water is H20, so that means 2 hydrogen and 1 oxygen. The atomic mass of hydrogen is 1 and atomic mass of oxygen is 16. Therefore MM= 1 + 1 + 16= 18.
Plug that value in and the full equation is
n = 36.04/18
n = 2.002 moles
= 2 moles

Answer: The positively charged ions will be attracted to the negative electrode and gain electrons. Meanwhile, the negatively charged ions will be attracted to the positive electrode and release electrons.
Explanation:
Electrolysis is breaking down of a substance into its constituents by the action of electrical current.
Cations wich are positively charged specie moves towards the negatively charged electrode that is towards the cathode. On reaching cathode, cations accepts electrons and get reduced through reduction reaction.
Anions wich are negatively charged specie moves towards the positively charged electrode that is towards the anode. On reaching anode, anions donate electrons and get oxidized through oxidation reaction.
