Answer:
organic compounds are classified based on functoin group
Explanation:
functional group is part of molecule or compound that determine the properties of that molecule or compound.
In chemistry, organic compounds are substances that have a covalently linked carbon atom. These compounds are classified based on the functional group and structures.
What are organic compounds?Organic compounds are said to be the compounds that have the presence of the carbon atom/s linked to the other atoms including nitrogen, oxygen, and hydrogen through a covalent bond.
The organic compounds are classified based on their structures and functional groups attached to their side chains. The functional groups include alkynes, alkenes, alcohols, carbonyl, nitriles, amines, etc.
The compounds can also be categorized based on the open or closed chain structures that can be homocyclic or heterocyclic. Further, the compounds can be aromatic or alicyclic.
Therefore, organic compounds are classified based on their functional groups and structures.

Answer:
The halogenation of propane discloses an interesting feature of these reactions. All the hydrogens in a complex alkane do not exhibit equal reactivity. For example, propane has eight hydrogens, six of them being structurally equivalent primary, and the other two being secondary
2. What is the mass of 5.3 moles of CaCl2?
Answer:
590 g CaCl₂
General Formulas and Concepts:
Chemistry - Atomic Structure
Reading a Periodic TableUsing Dimensional AnalysisExplanation:
Step 1: Define
5.3 mol CaCl₂
Step 2: Identify Conversions
Molar Mass of Ca - 40.08 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of CaCl₂ - 40.08 + 2(35.45) = 110.98 g/mol
Step 3: Convert
[tex]5.3 \ mol \ CaCl_2(\frac{110.98 \ g \ CaCl_2}{1 \ mol \ CaCl_2} )[/tex] = 588.194 g CaCl₂

pls this is my second time asking these questions, i'm sorry, but i really need help!!! 1. what happens to atoms when there is a chemical reaction? 2. what are the rules that have to be followed for atoms? 3. what do these rules mean for chemical reactions? sorry, chemistry isn’t really my best subject lol
Answer:
the atoms of the original substances gain, lose and even share their very own electrons. write the symbols of the elements that form the compound. Write down the valency, and lastly go over valencies. This is all I got so far. I hope this helps
Explanation:
What happens when an object
returns to its original shape-does it
still have elastic energy?
Answer:
Elastic potential energy is energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process. The deformation could involve compressing, stretching, or twisting the object.

Explain why, in a balanced chemical equation C + O2 CO2, we know that 1 gram of C will not react exactly with 1 gram of O2.
Answer:
See the answer below
Explanation:
From the equation, 1 mole of C requires 1 mole of O2 for a balanced reaction.
1 g of C will not exactly react with 1 g of O2 because the 1 g of each of the reactants contain different amounts of the substance.
The amount (in moles) of a substance is the mass of that substance divided by the molar mass.
Hence, 1 g of C will contain 1/12 moles of the substance while 1 g of O2 will contain 1/32 moles of the substance.
Is the substance in the chart a metal or non metal? Explain.

Explain why Ra is larger than Be. With 2 points.
Explanation:
Radium(Ra)=>atomic number=88
BERYLLIUM (Be)=>atomic number =4
why is Ra larger than Be
1. since the atomic number of Ra is greater than Be, the number of electrons is more, which means there are more number of shells present in Ra than Be. (atomic Radius)2. the more the valence electron (excluding fully filled ones) the less is the nuclear attraction forcesince Ra has more valence electron in its outermost shell, the nuclear attraction force is less which means that Ra 's size is greater than Be.hope it helps:)

Can one mole of peas fit inside your house? List the materials and steps of an experiment that answers the
question without actually filling up your house with peas!
Answer:
No.
Explanation:
No, one mole of peas do not fit inside a house because one mole is equals to 6.022 × 10²³ units which is a very large value. mole only use for atoms, ions and molecules etc due to very small size but mole is not used for big sized materials such as peas and other vegetables etc. So that's why we can conclude that one mole of peas did not fit inside a house.

A pH of 1 there are a lot of ______ in a solution. 2.A pH of 14 there are a lot of ______ in a solution.
Answer:
Hydrogen or hydroxonium ions in the solution
Hydroxyl ions in the solution
Explanation:
A pH of 1 shows there is a lot of hydroxonium ions in the solution and a pH of 14 shows there is a lot of hydroxyl ions in the solution.
The pH scale ranges from 1 to 14 As the values tends towards 1, the acidity increases due to concentration of hydroxonium ions in the solution. As the pH tends towards 14, the basicity increases due to the concentration of hydrogen ions in the solution.______________- the layers of soil. More mature (older) soils have more of these layers
fill in the blank please
I am not sure why your teacher isn't asking for the layers, but here is the list of layers;
A -(topsoil) Mostly minerals from parent material with organic matter incorporated. A good material for plants and other organisms to live.
E - (eluviated) - Leached of clay, minerals, and organic matter, leaving a concentration of sand and silt particles of quartz or other resistant materials – missing in some soils but often found in older soils and forest soils.
B - (subsoil) Rich in minerals that leached (moved down) from the A or E horizons and accumulated here.
C - (parent material) The deposit at Earth’s surface from which the soil developed.
R - (bedrock) A mass of rock such as granite, basalt, quartzite, limestone or sandstone that forms the parent material for some soils – if the bedrock is close enough to the surface to weather. This is not soil and is located under the C horizon.

calculate the percentage of iron in iron (III) sulphate
Answer:
28.01 percent
Explanation:
Iron (III) sulphate, [tex]Fe_2(SO_4)_3[/tex], has 2 atoms of Fe.
One atom of Fe has a molar weight of 56. Hence, 2 atoms of Fe would have a total molar weight of 56 x 2 = 112 g/mol
Molar weight of [tex]Fe_2(SO_4)_3[/tex] = 399.88 g/mol
Percentage Fe in [tex]Fe_2(SO_4)_3[/tex] = 112/399.88 x 100%
= 28.01%
The percentage of iron is iron (III) sulphate is, therefore, 28.01 percent.
Elena makes the table below to determine the number of atoms of each element in the chemical formula 3(NH4)2SO4. A table with 3 columns and 4 rows. The first column labeled element has entries nitrogen, hydrogen, sulfur, oxygen. The second column labeled calculation has entries 1 times 2 times 3 , 4 times 2 times 3, 1 times 4 times 3, 4 times 3. The third column labeled total atoms has entries 6, 24, 12, 12. What mistake did Elena make? She should not have multiplied the sulfur atoms by the subscript 4. She should not have multiplied the nitrogen atoms by the subscript 2. She should not have multiplied the oxygen atoms by the coefficient 3. She should not have multiplied the hydrogen atoms by the coefficient 3.
