Answer: Correct name will be is aluminum bromide

Explanation:

In a molecular formula , $AlBr_3$

Aluminium atoms present = 1

Bromine atoms present = 3

Charge on aluminium is +3 and charge on bromine is -1.

While naming:

Name of the cation is written first. Simple name of the element is written
After name of cation name of an anions written with suffix 'ide' in the end.

So, the name of $AlBr_3$ will be aluminium bromide.

The element iodine would be expected to form covalent bond(s) in order to obey the octet rule. Use the octet rule to predict the

zhannawk [14.2K]

Answer:

HI (hydrogen iodide).

Explanation:

Hello,

In this case, since iodine is in group VIIA, it has seven valence electrons at its outer shell, which means that it only needs one bond to attain the octet. Moreover, since hydrogen has just one electron at its outer shell, one hydrogen turns out enough to obey the octet when hydrogen and iodine bond as shown below:

$H-I$

Therefore, the required formula is:

$HI$

Which is hydrogen iodide.

Best regards.

Find the empirical formula of the compound ribose, a simple sugar often used as a nutritional supplement. A 14.229 g sample of r

MakcuM [25]

Answer:

CH2O

Explanation:

Firstly, we need to convert the masses of the elements to percentage compositions. This can be done by placing the mass of each element over the total mass multiplied by 100% . We can start with carbon.

C = 5.692/14.229 * 100 = 40%

O = 7.582/14.229 * 100 = 53.29%

H = 0.955/14.229 * 100 = 6.71%

We then proceed to divide each percentage composition by their atomic mass of 12, 16 and 1 respectively.

C = 40/12 = 3.333

O = 53.29/16 = 3.33

H = 6.71/2 = 6.71

Dividing by the smaller value which is 3.33

C = 3.33/3.33 = 1

O = 3.33/3.33= 1

H = 6.71/3.33 = 2

The empirical formula of the compound ribose is CH2O
