Answer:

[tex]tin \: sulphar gold \: are \: not \: mixture \: \\ they \: are \: elements \: \: others \: are \: mixture \\ thank \: you[/tex]

Tin, sulfur, and gold are not a mixture because they are pure elements.

Pure substances can be described as elements that cannot be broken down into simple substances because they have only one type of atom in the whole composition.

A pure substance can be described as composed of two or more elements that are chemically combined and have a set composition such kind of pure substance is known as a compound.

A mixture can be described as made up of two or more different substances which are just physically combined but not chemically. A mixture can be separated into its initial components.

The composition of a heterogeneous mixture is non-uniform throughout the mixture while the composition of a homogeneous mixture is always the same in the entire mixture.

Therefore, tin, sulfur, and gold are pure elements, not a mixture.

answer : Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen.

Answer:

no

Explanation:

changing the number of protons will change the atomic number, and if the atomic number is changed, it will become a different element. if you give oxygen 9 protons, it would no longer be oxygen, it would be fluoride.

Answer: Which statement is always true when nuclear fusion occurs: The combined number of protons and neutrons remains constant.

21H+ 21H→ 42H+energy

Which statement best describes the mass numbers of the atoms in the reaction? There are two atoms with mass numbers of 2.

Which fact is true during a fission chain reaction? The number of freely-moving neutrons increases over time.

Explanation:

The statement which is always true when nuclear fusion occurs is "the combined number of protons and neutrons remains constant".

Nuclear fusion is a type of reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.

Fission chain reaction is a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats.

Answer:

4 g / cm^3

Explanation:

Mass = 32 g

Volume of cube = 2 x 2 x 2 = 8 cm^3

Formula : -

Density = Mass / Volume

Density = 32 / 8

Density = 4 g / cm^3

Answer:

Paper burning

Explanation:

Answer:0.691 g/cm^3

Explanation: Density tells us how much mass there is per unit volume of a material.  If one has a density of 2 g/cm^3, then a 2 cm^3 chuck of it whould have a mass of (2 g/cm^3)*(2 cm^3) = 4 g.

Since the plastic is in the form of a cube, we can calculate it's volume with the relationship V = l^3, where l is the length.  (A box would have a volume of lengthx width x height, but for a cube, l=w=h, so the equation becomes V = l^3.

The colume of the plastic cube is (1.5cm)^3 or 3.375 cm^3.  Since this cube has a mass of 2.331 g, we can divide that mass by the cube's volume to find density:

(2.331 g)/(3.375 cm^3) = 0.691 g/cm^3

Answer:

When the sun's rays shine down on a plant, the chlorophyll capture the energy from the sun and use it during photosynthesis to make sugars. Sugar is the energy source for plants, that is why sunlight and photosynthesis is so important

The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

Answer:

The measure of central tendency helps you find the middle or the average, of a data set.  The three most common measures of central tendency are the mean, median and mode.  The mean is the most frequent value. The median is the middle number in an ordered data set. The mean is the sum of all values divided by the total number of values

Explanation:

Sum of Data  (mean)           Data in size order (median)                Mode

2 +1 + 4+7 + 1 = 15                    1,    1 ,    2,     4,      7                   Most common

15 /5 =  3                                                                                      value is 1                                                                                      

Mean = 3                                        Median  =  2                         Mode = 1

Answer:

33

Explanation:

as the atomic number states the number of protons in each element hope this helps :)

Two or more than two atoms with different physical or chemical properties can not combine together to form an element.  The number of proton is 33 when the atomic number is 33 and atomic mass is 75amu.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same. Every element has different atomic number.

For a given element

atomic number= number of protons = number of electrons

For given arsenic element atomic number is 33 so according to above relation, we can find the number of protons easily.

atomic number=33

number of protons =33

Therefore, the number of proton is 33 when the atomic number is 33 and atomic mass is 75amu.
