Answer:
Molar mass = 27 g/mol
Explanation:
Given data;
Number of moles of Al = 0.2 mol
Mass of Al = 5.4 g
Molar mass of Al = ?
Solution:
Formula:
Number of moles = mass/molar mass
By putting values,
0.2 mol = 5.4 g/ molar mass
Molar mass = 5.4 g/ 0.2 mol
Molar mass = 27 g/mol
I believe its Lithium Sulfide
Answer:
Bleach, seawater, blood, water, coffee, orange, lemon
Explanation:
The pH is a measurement in chemistry defined as the -log [H⁺]. pH is used in quality control of materials. The pH is a scale from 1 (Acids) to 14 (Bases). The pH of 7 is for neutral solutions
Based on the information of the image, the most basic is bleach, then the seawater, the blood, water (Neutral), coffee, orange and, the most acidic is lemon.
The order is:
<h3>Bleach, seawater, blood, water, coffee, orange, lemon</h3>
