Explanation:
pH is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution.
Not quite sure what you mean by matter ? Yes air is matter and yes it does matter ! Air is various gasses that support life and other things ! We use air for so many things, it's very important c:
The density of the liquid is 1.3 g/mL.
The mass of the liquid is 0.16 kg = 160 g.
The volume of the liquid is 125 mL.
Density = mass/volume = 160 g/125 mL = 1.3 g/mL
the mass of the shells will remain the same because you can not change mass even if you were to leave this planet and go to the moon your weight would change but your mass remains the same
1) is the answer because the only way to turn it from blue to yellow is to mix it with an acidic solution.
