Define not matter and give examples
Answers
Answer:
Everything that has mass and takes up space is matter. Every day, you encounter phenomena that either don't have mass or don't take up space. They are non-matter. Basically, any type of energy or any abstract concept is an example of something that is not matter.

A table.
Air.
Water.
A computer.
Paper.

Answer:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

Explanation: they contain sodium, potassium, chloride, bicarbonate, calcium, phosphate, magnesium, copper, zinc, manganese, molybdenum, copper, and chromium also.
b) They both have the same mass.
c) A mole of magnesium has more mass.
d) They both have the same number of atoms.
Answers
Answer: d) They both have the same number of atoms.
Explanation:
A mole is defined as the amount of substance that contains Avogardro number of the substance. Avogadro's number is given by .
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number
Thus 1 mole of magnesium and iron both contains particles.

D.iodine-127
Answers
Explanation:
1) As per the definition of nuclide, it is the atomic spieces (the atom) characterized by the nucleons (protons and neutros).
2) To notation for a nuclide is the name of the atom followed by a hypen (without blank spaces) and the mass number.
3) The mass number is the sum of protons and neutrons.
4) From that, you can tell this about the four choices given:
A.iodine-53: is not correct because that would mean that the mass number is 53, which cannot be right as the atomic number of iodine is 53 meaning that it has 53 protons, and so that notation is not including the neutrons.
B.iodide-53: is not correct because the name of the atom is iodine, not iodide (also the mass number cannot be for the same reason explained above)
The name iodide is reserved for the ions from iodine not for the atom.
C.iodide-127: incorrect due to the name iodide, for the same reason explained above.
D.iodine-127: this is correct choice. It is the name of the isotope of the iodine with mass number 127, which means that the atom has 53 protons and 74 neutrons (53 is the atomic number and 74 is calculated from 127 - 53)

A mixture is a combination of two or more substances without any chemical reaction occurring between them. Components of a mixture can be separated using physical methods such as heating, filtering, evaporation, .... etc
A two-phase mixture is a type of mixture that contains two different phases of matter, for example solid and liquid phases in one mixture or liquid and gas phases in one mixture.
Now, we can give examples of two-phase mixtures and mention how to separate them:
A mixture of sand and water is considered a two-phase mixture (sand is sold and water is a liquid).
The components can easily be separated using filtration where the sand will remain on the filter paper and water will pass.
Another example is a mixture of sugar and water (sugar is a solid and water is a liquid).
The components can be separated by heating. We can eat the mixture until water evaporates and the sugar is precipitated. The evaporated water can then be condensed into a different container.
Hope this helps :)

Further explanation:
Mixture:
The material that is made up of two or more substances is called a mixture. It has no fixed formula and its composition is also varied. All the individual constituents retain their properties after the formation of the mixture.
Types of mixtures:
1. Homogeneous mixtures
Homogeneous is a Latin word that means the same. These mixtures have a uniform composition throughout. These types of mixtures consist of a single phase only. Air, orange juice and blood are the examples of a homogenous mixture.
2. Heterogeneous mixtures
Heterogeneous is a Latin word that means different. These mixtures that have non-uniform composition throughout. These mixtures have more than one phase. Concrete, soda and chocolate chip cookies are the examples of a heterogeneous mixture.
Characteristics of mixtures:
1. It has a variable composition and has no formula.
2. Mixtures are not formed by any chemical reactions.
3. Mixtures can be either homogeneous or heterogeneous.
4. The constituents of the mixtures can be separated by physical methods such as filtration, heating, drying, distillation, crystallization.
5. The properties of the individual particles of the mixture are retained even after the formation of mixtures.
A mixture of sand and water is an example of a two-phase mixture. Here sand is a solid whereas water is a liquid. The components of the mixture are separated by filtration. Sand will remain on the surface of filter paper while water passes through it.
