Answer:
I think everything that's there is correct.
Explanation:
Bleach with pH of about 12.5 would be a strong base.
Milk with pH of 6.5 and Blood with pH around 7 would be neutral.
Battery acid with pH below 1 is strong acid and orange juice is weak acid.
Answer:
I guess 4 weeks is a little late.
Explanation:
The Earth, Mars or Jupiter should be denser than the Sun. Density is defined by mass and volume — components of object or matter. Although the sun is huge, it’s component is made up of mostly gas (hydrogen and helium). While Earth, though smaller than the Sun, contains heavier elements such as iron, sulfur, rocks, sediments, granite, basalt and water. Mars (composed of rocks and nutrients) and Jupiter (contains gases and compounds) as well are denser when compared to the Sun’s density. Referencing to our basic understanding of matter: solid and liquid should be heavier than gas.
Answer:
The pH is 9,21.
Explanation:
The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as
pH = -log (H 30+)
pH= -log (6,2 x 10^-10)
<em>pH=9,21</em>
It would be any white dwarf star
