A change will only occur one time in unidirectional.
Because
Cyclic : Cyclic compounds are chemical compounds having a basic non-linear structure. In other words, these are ring structures. One or more series of atoms in the compound is connected to form a ring structure.
Periodic : The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic number.
Unidirectional : compound is operating or moving in one direction only and it does not move in other direction.
Bidirectional : Capable of reacting or functioning in two, usually opposite, directions.
Thus, A change will only occur one time in unidirectional.

Answer:
Ca(ClO3)2
Explanation:
The chemical formula of calcium chlorate is Ca(ClO3)2, which means in this molecule, Ca2+ ion is bonded to two ClO3- ions. So the formula can be expended to O3Cl-Ca-ClO3, or CaCl2O6 (basically times the numbers of the elements inside the bracket by the number outside the bracket.
Answer:
The main source of energy is the sun. The sun has a big part in the water cycle because it turns the water into water vapor. This cause the water cycle to start over again once it rains. Therefore, making the sun ne of the biggest parts in the water cycle.
Answer:
Bromine has one half filled orbital.
Explanation:
The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements. Their boiling points also increases down the group which changes their physical states. i.e fluorine is gas while bromine is liquid and iodine is solid.
Electronic configuration of bromine:
₃₅Br = [Ar] 3d¹⁰ 4s² 4p⁵
As it in known that p sub-shell consist of 3 orbitals px, py, pz and each orbital can accommodate only two electrons.
In bromine there are 5 electrons in 4p it means two electrons are present in px two in py ans one in pz. So the half filled orbital is only one.
Answer:
3.783×10²⁴
Explanation:
We know that one mole of water contain two moles of hydrogen atom and one mole of oxygen atom. shown in following equation:
2H₂ + O₂ → 2H₂O
And
1 mole of hydrogen = 6.022×10²³ atoms of hydrogen
The number 6.022×10²³ is called Avogadro number and it is the number of atoms in one mole of substance. While we have to find the hydrogen atoms in 3.14 moles of water
So the factor 3.14 given in the question contain
3.14×2×6.022×10²³ number of hydrogen atoms which is equal to the 3.783×10²⁴.
