Based on electronegativity differences, which bond is a polar covalent bond?
Answer:
A bond in which the electronegativity difference between the atoms is between 0.4 and 1.7 is called a polar covalent bond.
A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal.

how can you tell whether a substance is a binary compound
Given what we know, we can confirm that a compound will be a binary compound if it contains both a metal and a non-metal element.
Why does this combination form binary compounds?The reason for this is that metals will be able to donate electrons thanks to their chemical properties. Meanwhile, non-metal elements will seek to receive electrons to become more stable.For these reasons, metals and non-metals will come together to create covalent bonds, and thus, binary compounds.Therefore we can confirm that since a metal will donate its electron to a non-metal element to form covalent bonds, we will know if the compound is binary or not based on the presence of a metal and a non-metal.

Because only certain size electron orbits are allowable, the frequency and energy of the electron is ___ .
Because only certain size electron orbits are allowable, the frequency and energy of the electron is quantized
According to the Bohr model of the atom, an electron moves from a lower to a higher energy level when it absorbs energy. This energy is released when the electron returns to ground state.
According to the Bohr model, only certain size electron orbits are allowable hence the frequency and energy of the electron is quantized.

Each of these Ionic Compounds are named INCORRECTLY.
1. Find and describe the mistake
2. Correctly name the compound.
CaCl2 - Calcium Chlorine
CuS - Copper Sulfide
Li3P - Trilithium Phosphide
CuBr - Copper(II) Bromide
NaOH - Sodium Hydrogen Oxide
Explanation:
The nomenclature of ionic compounds is given by:
1. Positive is written first. And if the metal atom has various oxidation states then its oxidation state is to be mentioned in brackets with help of roman numbers
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
1.) : Calcium chloride (Correct)
In the given compound, calcium has oxidation state of +2 and chlorine has oxidation state of -1.The name is correct.
2.) : Copper (II) oxide (Incorrect)
In the given compound,copper has the oxidation state of +1 and oxygen has oxidation state of -2.So ,the correct name will be Copper (I) oxide.
3.) : Lead (II) sulfide (Incorrect)
In the given compound, lead has the oxidation state of +4 and sulfur has oxidation state of -2. So ,the correct name will be Lead (IV) sulfide.

Difference Between baking soda and baking powder
Answer:
Baking soda is sodium bicarbonate, which requires acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated. Substituting one for the other is possible with careful adjustments. Baking soda is strong. In fact, it is about 3-4x stronger than baking powder. More baking soda in a recipe doesn't necessarily mean more lift.
Explanation:
Explanation:
baking soda contains one ingredient, sodium bicarbonate. however, baking powder contains sodium bicarbonate , monocalcium phosphate and either sodium acid prophetess or sodium aluminum sulfate

what is the trend for atomic radii across the periods and down the group?
Answer:
So, in general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
Explanation:
Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.

An atom is electrically neutral when...
O The number of protons and neutrons are equal.
O The number of protons and electrons are equal.
O The number of neutrons and electrons are equal.
O The neutrons balance the protons and electrons.
Answer:
The number of protons and electrons are equal.
Explanation:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

There are 2 types of changes
Physical change :- The physical properties are changed and its temporary.Chemical change :- The chemical properties are changed and its permanent.when the orbitals or energy levels of an atom are full, it is considered to be stable. which atom in the ground state has a stable electron configuration?
Answer:
Noble gases, atoms which have complete filled outer orbits.
Explanation:
SInce, you have given no options elements like Neon, Helium,etc
Noble elements are the atoms which have stable electronic configuration in the ground state.
What is electronic configuration?
Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

at sea level, the average height of mercury in a barometer is
Answer: 760 mm
Explanation:
At sea level, a mercury column will rise a distance of 760 mm. At higher altitudes, the atmospheric pressure is decreased and so the column of mercury will not rise as high.
which scientist surmised the scientific principle that the position and momentum of an electron cannot be known simultaneously with a high degree of accuracy?
The scientific principle was surmised by Werner Heisenberg and it is called Heisenberg's uncertainty principle.
In 1927 German scientist Werner Heisenberg propounded the uncertainty principle which states that both the position and momentum of a particle cannot be measured simultaneously with certainty.
That is, the more accurate we measure the position of the particle, the less accurate we would measure its momentum.
Heisenberg's uncertainty principle is stated mathematically as ΔpΔx ≥ h/4π where p is the momentum, x is the position and h is Planck's constant.
So, the scientific principle was surmised by Werner Heisenberg and it is called Heisenberg's uncertainty principle.

How do animals and plants rely on each other in the prairie? ITS TIMED
There are many decomposers in the prairie that can be used as food sources for first-order consumers.
There is more sunlight in the prairie for plants to grow, and therefore more food sources for animals.
Second-order consumers eat the grass as their food source.
The grass in the prairie provides oxygen, while animals give off carbon dioxide gas.
Answer:
I would assume its the last one "The grass in the prairie provides oxygen, while animals give off carbon dioxide gas."
Explanation:
The question asks how the animals and plants rely on each other
The plants provide oxygen and food for the animals, and the animals provide carbon dioxide to them.
