Has prefixes tht identify the # of atoms of each element

Question 2

Acids tht have “hydro” are…

Answer 2

Binary compounds

Question 3

What are binary compounds?

Answer 3

Compounds of two elements, second element ends in “ide”

Question 4

Ionic compounds…

Answer 4

Have a metal plus a nonmetal

Question 5

How do you name binary ionic compounds?

Answer 5

First element (positive) second element (negative) and ends in “ide”

Question 6

What is a hydrate?

Answer 6

A salt with water weakly attached

I.e: sodium sulfate • pentahydrate

Question 7

To name hydrates you…

Answer 7

Name the salt plus prefix for moles of water plus hydrogen

Question 8

A ternary compound…

Answer 8

Composed of two or more elements, both ionic and covalent, has a polyatomic ion

Question 9

What is a polyatomic ion?

Answer 9

A group of atoms that act as a single atom with a charge

Question 10

For acids ic and ous mean…?

Answer 10

Ic - ate

Ous- ite

Question 11

For polyatomics how do ic’s and ous’s O2’s relate?

Answer 11

Ates have one more O2 than ites

Question 12

Empirical formulas are?

Answer 12

Whole number ratios of elements in a given compound

Question 13

In order to do an empirical formula you…?

Answer 13

Assume g sample if in %
Convert to moles (3 sig figs)
Divide each mole by smallest number of moles
Multiply by common whole number to get a whole number if needed

Question 14

To find the molecular form…

Answer 14

Take the gram sample divided by the atomic mass of the empirical form

Question 15

What is the law of definite proportions?

Answer 15

A given compound will always contain the same element in the same proportions by mass
(No matter how much water there is, it will always have 2 hydrogens for every one oxygen)

Question 16

What is the law of multiple proportions?

Answer 16

When two elements form a series of compounds, the ratios of the masses of the 2nd element combine with 1g of the 1st element can always reduce to a whole number ratio

Question 17

What is law of multiple proportions in normal words?

Answer 17

Nitrogen and oxygen can make many compounds, but their subscripts will always hav a whole number ratio

Question 18

What is the law of conservation of masses?

Answer 18

Qualitative- tells what elements are in a compound

Quantitative- tells how much of each element is in a compound

Question 19

How do you find the percent compostition?

Answer 19

Mass of an element over mass of compound multiplied by 100
