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.

Answer:
120 moles of Mg
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
3Mg + 2H₃PO₄ —> Mg₃(PO₄)₂ + 3H₂
From the balanced equation above,
3 moles of Mg reacted to produce 3 moles of H₂.
Finally, we shall determine the number of mole of Mg needed to produce 120 moles of H₂. This can be obtained as follow:
From the balanced equation above,
3 moles of Mg reacted to produce 3 moles of H₂.
Therefore, 120 moles of Mg will also react to produce 120 moles of H₂.
Thus, 120 moles of Mg is needed for the reaction.

How many atoms are in a sample of silver if the sample had a mass of 1243 g ?
Answer:
69.37×10²³ atoms of silver
Explanation:
Given data:
Mass of sample = 1243 g
Number of atoms of silver = ?
Solution:
Number of moles of silver:
Number of moles = mass/molar mass
Number of moles = 1243 g/ 107.87 g/mol
Number of moles = 11.52 mol
Number of atoms:
According to Avogadro Law,

An ion of an element can have the same ________ as another element.
Answer:
Number of electrons.
Explanation:
I hope this helps.
An ion is said to be the molecule or the atom that has the presence of a net electrical charge over them. An ion can have the same protons as the other elemental atom. Thus, option A is correct.
What is an ion?An ion is defined by the atom or the molecule with an electrical charge of positive and negative on them due to the gain or the loss of the electron in their orbits for the bond formations and stability.
The ions of the atom have the same number of protons in their nucleus but the number of the electrons varies as they looses and gain electron to acquire the positive and the negative charge over them.
The presence of the extra or less electron in the orbit or the shell of the atom makes them reactive and allows the electrostatic attraction between them for the bond formation.
Therefore, in option A. the protons are the same in an ion.

Use the reaction given below to solve the problem that follows: Calculate the mass in grams of aluminum oxide produced by the reaction of 15.0 g of aluminum metal.
[ ]grams Al2O3
4 Al + 3 O2 --> 2 Al2O3
**Your answer should be written as XX.X
Answer: 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Al=\frac{15.0g}{27g/mol}=0.556moles[/tex]
The balanced chemical equuation is:
[tex]4Al+3O_2\rightarrow 2Al_2O_3[/tex]
According to stoichiometry :
4 moles of [tex]Al[/tex] produce == 2 moles of [tex]Al_2O_3[/tex]
Thus 0.556 moles of [tex]Al[/tex] will produce=[tex]\frac{2}{4}\times 0.556=0.278moles[/tex] of [tex]Al_2O_3[/tex]
Mass of [tex]Al_2O_3=moles\times {\text {Molar mass}}=0.278moles\times 102g/mol=28.4g[/tex]
Thus 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal.

Rubidium has two common isotopes, 85Rb and 87Rb. If the abundance of 85Rb is 72.2% and the abundance of 87Rb is 27.8%, what is the average atomic mass of rubidium
Answer:
85.556 amu
Explanation:
From the question given above, the following data were:
Isotope A (85–Rb):
Mass of A = 85 amu
Abundance (A%) = 72.2%
Isotope B (87–Rb):
Mass of B = 87 amu
Abundance (B%) = 27.8%
Average Atomic mass of rubidium =?
The average atomic mass of rubidium can be obtained as follow:
AVERAGE = [(Mass of A × A%)/100] + [(Mass of B × B%)/100)]
AVERAGE = [(85 × 72.2)/100] + [(87 × 27.8)/100]
= 61.37 + 24.186
= 85.556 amu
Therefore, the average atomic mass of rubidium is 85.555 amu

A laboratory investigation included examining prepared slides of pond water. Single-celled organisms with a nucleus and either cilia or flagella were visible. These organisms probably belong to kingdom
Answer:
Protista
Explanation:
The organisms would probably belong to the kingdom Protista.
Organisms in the Protist kingdom are unicellular and animal-like. They possess all the attributes of animals except the fact that they are unicellular. They are different from fungi in being mobile and being able to ingest their foods. Unlike monera, protists are eukaryotic and unlike plants, most protists are heterotrophic (except euglena).
The cells of protists possess nuclei and locomotive structures such as pseudopodia (e. amoeba), cilia (e.g paramecium), and flagella (e.g euglena).
Hence, the organisms seen on the prepared slides of pond of water would probably belong to the Protist kingdom.
These organisms belong to the Kingdom known as Protista.
Protists are referred to eukaryotes which are mostly unicellular(single-celled) and examples include
AmoebaFlagellates CiliatesSporozoans.They are also microscopic and can't be seen with the naked eyes. In this
scenario, we were told that the pond contains single-celled organisms which
have cilia and flagella . This depicts that the organisms fall under the
kingdom Protista.

Justifica cuál de las tres medidas siguientes es mejor. a) Una masa de 3 kg con un error absoluto de 1 g. b) Una masa de 4 g con un error absoluto de 1 mg. c) Una masa de 95 kg con un error absoluto de 1 kg.
Answer:
La mejor medida, con el error porcentual más pequeño de 0.025% es una masa de 4 g con un error absoluto de 1 mg
Explanation:
Tenemos el error porcentual dado como sigue;
[tex]El \ porcentaje \ error =\dfrac{\left | v_A - v_e \right |}{v_E} \times 100[/tex]
Dónde;
[tex]\left | v_A - v_e \right | = Error \, absoluto[/tex]
[tex]v_e[/tex] = El valor esperado
La mejor medida tiene el menor porcentaje de error;
a) Para una masa de 3 kg con un error absoluto de 1 g, tenemos;
El valor esperado, [tex]v_e[/tex] = 3 kg
Error absoluto = [tex]\left | v_A - v_e \right |[/tex] = 1 g = 0.001 kg
Que da el error porcentual = 0.001/3 × 100 = 0.0[tex]\bar 3[/tex]%
b) Una masa de 4 g con un error absoluto de 1 mg = 0,001 g
El valor esperado, [tex]v_e[/tex] = 4 g
Error absoluto= [tex]\left | v_A - v_e \right |[/tex] = 1 mg g = 0.001 g
El porcentaje de error = 0.001/4 × 100 = 0.025%
c) La masa medida dada = 95 kg
El error absoluto = 1 kg
El valor esperado, [tex]v_e[/tex] = 95 kg
Error absoluto = [tex]\left | v_A - v_e \right |[/tex] = 1 kg
El porcentaje de error = 1/95 × 100 ≈ 1.053%.
Por lo tanto, la mejor medida, con el menor porcentaje de error de 0.025% es una masa de 4 g con un error absoluto de 1 mg.

Which relationship explains how the water can boil at room temperature?
A Lower air pressure results in a lower boiling point
B. Lower air temperature results in a lower boiling point
C. Lower air pressure results in a higher boiling point
D. Lower at temperature results in a higher boiling point
Answer:
Option A.
Lower air pressure results in a lower boiling point
Explanation:
This is because in an open system, the lower the pressure the lesser the energy that will be required for boiling point. The is little or no collision of air molecules with the surface of the liquid
But if there is increase in pressure, more energy will be required to get to boiling point because there will be strong collision between air molecules and surface of the liquid.

Answer:a
Explanation:I think
[tex]C_6H_{12}O_6+O_2[/tex] → [tex]H_2O+CO_2[/tex] equation correctly describes the reaction. Hence, option A is correct.
What is glucose?Glucose is the main type of sugar in the blood and is the major source of energy for the body's cells.
Burning wood provides heat through the exothermic chemical reaction of oxygen (O) with cellulose ([tex]C_6H_{12}O_6[/tex]), the major chemical component of wood, to produce carbon dioxide ([tex]CO_2[/tex]), steam ([tex]H_2O[/tex]) and heat.
The chemical reaction describing the process is
[tex]C_6H_{12}O_6+O_2[/tex] → [tex]H_2O+CO_2[/tex] +heat
Hence, option A is correct.
