Answer:
Molecular Formula = C₄O₂H₈
Explanation:
Molecular formula is calculated from following formula.
Molecular Formula = n(Empirical formula)
The formula for n is given as,
n = Molecular Formula Mass / Empirical Formula Mass
Molecular Formula mass = 88 g/mol
Empirical formula mass = 44
Putting values,
n = 88 / 44 = 2
Now,
Molecular Formula = 2(C₂OH₄)
Molecular Formula = C₄O₂H₈
1.) Write down the number of atoms that comprise each compound on either side of the equation. Using the chemical equation you can identify the atoms of each element in the reaction. Because a chemical reaction can never create or destroy new matter, a given equation is unbalanced if the number (and types) of atoms on each side of the equation don't perfectly match.Don’t forget to multiply through by a coefficient or subscript if one is present.
For example, H2SO4 + Fe ---> Fe2(SO4)3 + H2On the reactant (left) side of the equation there are 2 H, 1 S, 4 O, and 1 Fe.On the product (right) side of the equation there are 2H, 3 S, 12 O, and 2 Fe.
Answer: (3) ppm
Explanation: Concentration is defined as the amount of solute dissolved in a known amount of the solvent or a solution.
Parts per million (ppm) is used to express the concentration when a very small quantity of solute is present in a large quantity of the solution. It is defined as the mass of solute present in one milion 
parts by mass of the solution.
L/s is used to express flow rate.
J/g is used to express energy per unit mass.
kPa is used to express pressure.
Water is the solvent. The solution is an aqueous solution, I believe.
The answer is it contains the electrodes. Without the salt scaffold, the arrangement in the anode compartment would turn out to be decidedly charged and the arrangement in the cathode compartment would turn out to be contrarily charged, on account of the charge lopsidedness, the terminal response would rapidly stop.
It keeps up the stream of electrons from the oxidation half-cell to a decrease half cell, this finishes the circuit.
