Answer: The standard free energy change for a reaction in an electrolytic cell is always positive.

Explanation:

Electrolytic cells use electric currents to drive a non-spontaneous reaction forward.

Relation of standard free energy change and emf of cell

$\Delta G^o=-nFE^0_{cell}$

where,

$\Delta G^o$ = standard free energy change

n= no of electrons gained or lost

F= faraday's constant

$E^0_{cell}$ = standard emf

$E^0_{cell}$ = standard emf = -ve , for non spontaneous reaction

Thus $\Delta G^o=(-ve)(-ve)=+ve$

Thus standard free energy change for a reaction in an electrolytic cell is always positive.

Mendeleev positioned elements in the periodic table in increasing order of their atomic numbers, such that elements having identical chemical properties and characteristics plunge into the same group.

What is Mendeleev's periodic table called?

In order to represent similarities and patterns in the behavior of elements, Mendeleev created the periodic table, which is an arrangement of elements in an increasing atomic mass order in tablet form.
Mendeleev stated that "Element characteristics are a periodic function of their atomic weight" in his renowned periodic law.
The Periodic Table of Mendeleev is a table that Mendeleev created to list elements in the order of their atomic weights.

Mendeleev discovered that there were two elements with atomic weights between 65.2 and 75 because he found it very satisfying that the properties of the elements were more similar and closer to this level.
He also imagined having other elements with possessions similar to those of these other elements.
In the periodic table, he left a blank for these two elements until they were finally discovered in their true existence.

The most common isotopic forms of hydrogen are ordinary hydrogen (1H) and deuterium (2H), which have percent compositions of 99.

Alborosie

Answer:

0. 000115

Explanation:

A percentage is defined as a ratio with a basis of 100 as total substance. Convert a percentage to decimal implies to divide the percentage in 100 because decimal form has as basis 1.

For the isotopic forms:

1H: 99.98% → As percent.

99.98% / 100 = 0.9998 → As decimal form.

2H: 0.0115% → As percent.

0.0115% / 100 = 0. 000115→ As decimal form.
