Which formulas represent one iconic compound and one molecular compound

Chemistry
1 answer:
Kisachek [45]3 years ago
6 0
An ionic compound is any compound containing a metal and a nonmetal

For example: NaCl, MgO, etc

Sometimes they’ll include polyatomic ions, such as CN (cyanide), ClO3 (chlorate), and many others

For example: NaCN, LiClO3, etc


A covalent or molecular compound usually contains shared pairs of electrons

Some examples are H2O, CO2, CHCl3

Notice, that these are all composed of non-metals.


Hope this helps. It’s hard to answer specifically when I can’t see the options.

If this helps, give me a brainliest, so I know I was helpful.

How many kilograms of potassium iodide (ki) are needed to make 1.25 l of a 4.41 m ki solution?
Lapatulllka [165]
C = n/V
n = C×V
n = 4,41M × 1,25L
n = 5,5125 mol

mKI: 39+127 = 166 g/mol

1 mol --------- 166g
5,5125 mol --- X
X = 166×5,5125 = 915,075g KI

Suppose a solution was too concentrated for an accurate reading with the spectrophotometer. The concentrated solution was dilute
yan [13]
Using the law of <span>dilution:

</span>initial Molarity = 3.5x10⁻⁶ M

<span>Initial volume = 4.00 mL
</span>
final Molarity = ??

final volume = 1.00 mL

Therefore:

Mi x Vi = Mf x Vf

(3.5x10⁻⁶) x 4.00 = Mf x 1.00

1.4x10⁻⁵ = Mf x 1.00

Mf = 1.4x10⁻⁵ / 1.00 = 

 1.4x10⁻⁵ M

12. Complete each of the following word equations for synthesis reactions.
Vlada [557]

Explanation:

12)

a) Sodium + oxygen = ?

When sodium reacts oxygen its forms sodium oxide as a product.

4Na(s)+O_2(g)\rightarrow 2Na_2O(s)

b) magnesium + fluorine = ?

When magnesium reacts with fluorine its forms magnesium fluoride as a product.

Mg(s)+F_2(g)\rightarrow MgF_2(s)

13)

a) 2HgO(s)\overset{\Delta }\rightarrow 2Hg(l)+O_2(g)

Decomposition of mercury(II) oxide on heating gives out mercury and oxygen gas.

b)2H_2O(l)\overset{Electricity}\rightarrow 2H_2(g)+O_2(g)

The electrolytic decomposition of water gives out hydrogen gas amd oxygen gas.
