The physical and chemical changes that occur in a system are alike because they change the state of the reactants. They are different because a chemical change produces a new substance while a physical change does not produce any new substance.
Differ in physical:
1. A difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
2. Be observed without changing the identity of the substance
3. Can be seen or measured without changing a material.
Differ in Chemical:
1. There is a change of the substances in question
2. determines how a substance changes into a completely different substance.
3. Tells how the substance forms new substances when it mixes with something else.

How are all physical changes alike?
All physical changes involve a change in the form, shape, or state of matter without altering the chemical composition of the substance. This means that the particles in the substance remain the same before and after the change, only their arrangement or state is altered.
How are 2 isomers alike and how are they different?
Isomers are alike in that they have the same molecular formula but different structural arrangement of atoms. They are different in their chemical and physical properties due to their distinct structural arrangements, which can result in differences in reactivity, boiling points, melting points, and other properties.
How are the isotopes of an element are alike and how are they different?
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
Is it always possible to distinguish two substances from one another based on their appearance explain your answer using specific examples?
Generally is not possible; a chemical/physical analysis is needed.Examples: the appearance of sodium chloride and potassium chloride is similar, the appearance of ethanol and methanol is similar etc.
What can be made of atoms that are different or atoms that are alike?
Atoms that are alike can form elements, while atoms that are different can combine to form compounds. Elements are substances made up of only one type of atom, whereas compounds are made up of different types of atoms bonded together in specific ratios.
How are physical changes alike?
all physical changes are alike in which all of them changing without changing in chemical makeup of the matter we have
How are chemical and physical weathering different and alike?
how are physical weathering and chenical weathering alike and different
How are physical weathering and chemical weathering alike?
how are physical weathering and chenical weathering alike and different
How are chemical and physical change alike?
They are alike because #1 they are a change insubstance, #2 the form is different. I hope i have been a huge help to people who need this for homework!
How are all physical changes alike?
All physical changes involve a change in the form, shape, or state of matter without altering the chemical composition of the substance. This means that the particles in the substance remain the same before and after the change, only their arrangement or state is altered.
How are physical weathering and chemical weathering alike and different?
Physical weathering and chemical weathering both involve the breakdown of rocks, but through different processes. Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their composition, while chemical weathering involves the alteration of rock composition through chemical reactions with substances like water, oxygen, and acids. Both processes contribute to the overall erosion of rocks and landforms over time.
Are Physical properties within a period are more alike than physical properties within a group?
No, physical properties within a group are more alike than physical properties within a period. This is because elements in the same group have similar electron configurations, leading to similar chemical and physical properties, while elements in the same period have different numbers of electron shells and therefore different properties.
Is it true that a physical change and a chemical are exactly alike?
Not true, they are not similar; a chemical change is a change in the molecule, the physical change is not.
How are 4 types of chemical reactions alike and different?
The 4 types of chemical reactions (synthesis, decomposition, single displacement, and double displacement) are alike in that they involve the rearrangement of atoms to form new compounds. They differ in terms of the specific changes that occur during the reaction, such as the number and types of substances involved, and the chemical bonds that are broken and formed.
How are chemical reactions different to reversable changes?
physical change is reversible because you can undo it for example: if you fold a paper you unfold the paper. chemical chang is irreversible because if you make somthing together you could not seperate them.
How are 2 isomers alike and how are they different?
Isomers are alike in that they have the same molecular formula but different structural arrangement of atoms. They are different in their chemical and physical properties due to their distinct structural arrangements, which can result in differences in reactivity, boiling points, melting points, and other properties.
How are two atoms of the same elements alike?
They have all the chemical, physical, nuclear properties identical. This is not the case for isotopes.
