<h3>Answer:</h3>

0.5 moles

Explanation:

moles are a way to compare different elements and are used a measurement of the amount of an element or molecule

I think your teacher wants you to convert 39g of Al(OH)3 to moles

we can use a method called stoichiometry to do this.

39g Al(OH)3 x 1 mol Al(OH)3 / 78g Al(OH)3 = 0.5 moles Al(OH)3

I got 78 by adding up the molar masses for Al, 3Os and 3Hs, make sure to add for 3 Os and Hs because of the subscript 3

Due to the low carbohydrate intake, ketosis occurs in which stored fat is metabolized which results in build up of acids called ketones

If the body starts to use energy sources other than carbohydrates then it means it is using the stored energy, gluconeogenesis fulfills glucose requirement of cell by synthesis of glucose from non carbohydrate material

To supply with energy lipid metabolism occurs, fatty acids are oxidized and energy in the form of ATP is produced
