What is a compound?Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds .Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

Do electrons spin in the same direction within an orbital?
Answer:
in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.

please help this is worth half of my grade! what letter represents the trough of the wave a,b,c,d,e
Hello good afternoon...God bless the answer to your following question is D
because...A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.

How many Nitrogen molecules are present? ___________
How many Oxygen molecules are present? ___________
How many N2O molecules are present? ___________
The molecules of Nitrogen, oxygen, and N₂O are 2, 1, and 2 respectively.
What is the chemical equation?A chemical equation can be defined as the expression of a chemical reaction in terms of the chemical symbols of the substances. A chemical equation has reactants, formed products, and an arrow indicating the direction of the reaction.
The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.
According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.
Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:
2N₂ + O₂ → 2N₂O
The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.

Isopropyl alcohol is a liquid with a density of 0.785 g/cm^3. How much volume would be taken up be 50.0 grams of isopropyl alcohol
Answer:
63.94 cm³Explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question we have
[tex]volume = \frac{50}{0.785} \\ = 63.694267...[/tex]
We have the final answer as
63.94 cm³Hope this helps you
lonic bonds tend to form between two atoms with what characteristics?
Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.
Explanation:
Ionic bonds tend to form between two atoms with a high electronegativity difference.
Explanation:
An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compoundsSo, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.

10. A gas sample that has a mass of 6g occupies 400 mL at 504°C and a pressure of 600 mm Hg. Calculate the gas’s density at STP.
Answer:
51 g/mol
Explanation:
Whenever you see molar masses in gas law questions, more often than not density will be involved. This question is no different. To solve this, however, we will first need to play with the combined ideal gas equation PV=nRT to make it work for density and molar mass. The derivation is simple but for the sake of time and space, I will skip it. Hence, just take my word for it that you will end up with the equation:

By the IUPAC Naming Convention followed by every chemical standards, the structure from the question is named as 4,4-dimethyl heptane.
IUPAC Stands for International Union of Pure and Applied Chemistry.This organisation issued some standards for naming any chemical components that is followed world wide.
According to the IUPAC Standards:
First of all we have to identify the longest carbon chain which is an alkane group according to this question.As a result of 7 carbon linked with single bonds it will be named heptane.Now moving to the other parts:
[tex]-CH3[/tex] is termed as methyl
As the both the methyl group( [tex]-CH3[/tex] ) is linked with the fourth carbon the numbering is 4 for methyl.So,the IUPAC name of this compound in the image is 4,4-dimethyl heptane.
