Answer:
Approximately
.
Explanation:

The actual yield of
was given. The theoretical yield needs to be calculated from the quantity of the reactant.
Balance the equation for the hydrolysis of water:
.
Note the ratio between the coefficient of
and
:
.
This ratio will be useful for finding the theoretical yield of
.
Look up the relative atomic mass of hydrogen and oxygen on a modern periodic table.
Calculate the formula mass of
and
:
.
.
Calculate the number of moles of molecules in
of
:
.
Make use of the ratio
to find the theoretical yield of
(in terms of number of moles of molecules.)
.
Calculate the mass of that approximately
of
(theoretical yield.)
.
That would correspond to the theoretical yield of
(in term of the mass of the product.)
Given that the actual yield is
, calculate the percentage yield:
.
the two process that occur in a cell are
oxidation: this is loss of electron by electrode. the metal electrode loaes electrons and get oxidized and forms ions
the ions get migrated to solution
Reduction: here the ions present in solution gains electron and get deposited on electrodes.
so gain of electrons is by ions
electrode gains electrons is where reduction occurs, and the half cell in which the electrode loses electrons is where oxidation occurs.
Answer:
An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals
Answer:
0.21 M
Explanation:
Molarity is the calculation of the solution in which the number of solute per liter of the solutions. It is the most common measurement unit that is used to measure the concentration of the solution.
The molarity is the unit that is used to measure or calculate the volume of the solvent. The amount of solvent is used in the chemical reaction.
The amount of the two solvent in the same quantity is measured by the formula called c1v1 and c2v2.
D, the more liquid there is, the less the temperature will be affected
