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.

The amount of heat absorbed by the water is 1606.6 J (383.99 Calories )

Initial temperature (T₁) = 21.5 °C

Final temperature (T₂) = 28.1 °C

ΔT = T₂ – T₁

ΔT = 28.1 – 21.5

Mass of water (M) = 58.18 g

Change in temperature (ΔT) = 6.6 °C

Specific heat capacity of water (C) = 4.184 J/gºC

Q = MCΔT

Q = 58.18 × 4.184 × 6.6

Divide by 4.184 to express in Calories

Q = 1606.6 / 4.184

Therefore, the amount of heat absorbed by the water is 1606.6 J (383.99 Calories )

Explanation:

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.

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.

Answer: There are three main factors that characterize the Bohr model. First, in the Bohr Model, the orbits have a set size and energy. There’s a correlation between energy and size: the smaller the orbit, the less energy it has. Electrons can move from one orbit to another by emitting or absorbing radiation.

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 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.
