Answer:

camphor sublimates salt is soluble in water while sand does not sublime and does not dissolve in water you first heat the mixture in a beaker covered with a watch glass camphor will then accumulate on the watch glass then you dissolve the remaining mixture of sand and salt salt will dissolve forming a salt solution then you filter using a filter paper and a beaker the residue on the filter paper is sand while the filtrate is salt solution you then heat the salt solution so that it can evaporate leaving salt particles thus you will have obtained salt sand and camphor

A 15.6 grams of ethanol absorb 868 J as it is heated. The initial temperature is 21.5 degrees Celsius. What is the final tempera
77julia77 [94]
You have to use the equation q=mcΔT and solve for T(final).  
T(final)=(q/mc)+T(initial)
q=the amount of energy absorbed or released (in this case 868J)
m=the mass of the sample (in this case 15.6g)
c= the specific heat capacity of the substance (in this case 2.41 J/g°C)
T(initial)=the initial temperature of the sample (in this case 21.5°C)

When you plug everything in, you should get 44.6°C.
Therefore the final temperature of ethanol is 44.6°C

I hope this helps.  Let me know if anything is unclear.

A formula unit represents the simplest ratio of elements in a______of an ionic compound.
ololo11 [35]

Answer: mole

A formula unit represents the simplest ratio of elements in a mole of an ionic compound.

Explanation:

The formula unit, also known as the empirical formula, gives the simplest whole number ratio of the components of the elements in a mole of an ionic compound.

Thus, the formula unit and the molecular formula of a compound can be the same.

For example: Glucose with C6H12O6 will have a formula unit of CH2O. Thus, the simplest ratio of carbon, hydrogen and oxygen in glucose is 1:2:1

For each ionic compound formula, identify the main group to which X belongs: (a) XF2;
Verizon [17]

(a) For the compound XF₂, X must be a metal. As fluorine is monovalent and there are two fluorine atoms, so the valency of X must be two.

Therefore, X belongs to group 2.

A metallic compound is a compound that contains one or more metal elements bonded to another element.

The elements are bonded with the help of metallic bonds.

Monovalent compounds are compounds which consist of an atom which has only a single covalent bond.

The covalent bond is defined as an interatomic linkage formed by sharing the electronic pair between two atoms.

Valency is the combining power of an element. It helps with bond formation.
