Tin, sulfur, and gold are not a mixture because they are pure elements.
What are the mixture and pure substance?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.

Consider the formula of the compound, calcium chloride. Select all the statements that apply to this image.
a) A covalent compound is formed
b) Chlorine becomes a negative ion
c) The chemical formula is CaCl2
d) Calcium transfers electrons to the chlorine atoms
e) The subscript 2, is used to balance the charges
Answers
Answer: Its B,C,D, and E
Explanation:
The correct statements about the compound calcium chloride are Chlorine becomes a negative ion, The chemical formula is CaCl₂, Calcium transfers electrons to the chlorine atoms and The subscript 2 is used to balance the charge.
Hence, Option B, C, D and E are correct.
Calcium ChlorideCalcium chloride is a crystalline white substance which is soluble in water. It is the chloride salt of calcium. The chemical formula of calcium chloride is CaCl₂. In calcium chloride, Calcium atom has two valence electrons.
Now lets check all statements one by one
Option (A): Calcium chloride is a ionic compound. Here calcium transfers its valence electrons to both chlorine atoms.
So, statement A is incorrect.
Option (B): In calcium chloride each chlorine atom gains 1 electron and we get a negatively charged ion Cl⁻.
So, statement B is correct.
Option (C): In Calcium chloride the valency of calcium is +2 and the valency of chlorine is -1. So the chemical formula is CaCl₂.
So, statement C is correct.
Option (D): In calcium chloride calcium transfer its two valence electrons to both the chlorine atoms.
So, statement D is correct.
Option (E): In calcium chloride the subscript 2 is used to balance the charge. The subscript show the number of atoms in compound.
So, statement E is correct.
Thus, from the above conclusions we can say that The correct statements about the compound calcium chloride are Chlorine becomes a negative ion, The chemical formula is CaCl₂, Calcium transfers electrons to the chlorine atoms and The subscript 2 is used to balance the charge.
Hence, Option B, C, D and E are correct.

If you combine sodium(Na) and chlorine(Cl) to make sodium chloride how many atoms of each will you need? Explain
Answers
Answer:
I don't understand but I can tell u this:
Na has one extra valence electron and Cl has one missing one. Chemical reactions and forming of compounds is all in the electrons and not the nucleus. So, when highly reactive Na mixes with Cl, they form a stable compound called NaCl, or table salt.
If we are making one molecule of sodium chloride, we need one sodium atom and one chlorine atom. The formula of sodium chloride is NaCl.
What is sodium chloride?Sodium chloride is an ionic compound formed by the combination of sodium and chlorine atoms. One molecule of sodium chloride contains one sodium and one chlorine atom to form NaCl. Now if we are making one mole of NaCl, we need 6.022 × 10²³ atoms of each element.
Sodium is a metal and possess extra one electron in its valence shell. Chlorine have 7 valence electrons thus, it needs one more electron to attain octet. Sodium donates its electron to chlorine and gains a positive charge.
Chlorine gains a negative charge by accepting the electron from sodium. This opposite charge clouds undergo electrostatic force of attraction. And thus, it an ionic bond forms between them.

The burning of a 0.37 g potato chip causes the temperature of 58.18 g of water in a soda can calorimeter to increase from 21.5℃ to 28.1℃. Calculate the amount of heat absorbed by the water. The specific heat of water is 4.184 J/g⋅℃. Express this answer in both Joules and Nutritional Calories.
Answers
The amount of heat absorbed by the water is 1606.6 J (383.99 Calories )
We'll begin by calculating the change in the temperature of the water.
Initial temperature (T₁) = 21.5 °C
Final temperature (T₂) = 28.1 °C
Change in temperature (ΔT) =?ΔT = T₂ – T₁
ΔT = 28.1 – 21.5
ΔT = 6.6 °CFinally, we shall determine the heat absorbed by the water. This can be obtained as follow:Mass of water (M) = 58.18 g
Change in temperature (ΔT) = 6.6 °C
Specific heat capacity of water (C) = 4.184 J/gºC
Heat absorbed (Q) =?Q = MCΔT
Q = 58.18 × 4.184 × 6.6
Q = 1606.6 JDivide by 4.184 to express in Calories
Q = 1606.6 / 4.184
Q = 383.99 CaloriesTherefore, the amount of heat absorbed by the water is 1606.6 J (383.99 Calories )

1. Write a paragraph of 3 lines on how a rainbow form
Answers
The most familiar type rainbow is produced when sunlight strikes raindrops in front of a viewer at a precise angle (42 degrees). Rainbows can also be viewed around fog, sea spray, or waterfalls.
A rainbow is an optical illusion—it does not actually exist in a specific spot in the sky. The appearance of a rainbow depends on where you're standing and where the sun (or other source of light) is shining.
The sun or other source of light is usually behind the person seeing the rainbow. In fact, the center of a primary rainbow is the antisolar point, the imaginary point exactly opposite the sun.
Answer:
Explanation:
A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun.
