Answer:
Lemon juice has lowest pH.
Explanation:
pH is the negative log of hydrogen ion concentration. By increasing the Hydrogen ion concentration pH will decrease.
pH = -log [H⁺]
According to pH scale,
The pH of 7 is consider neutral. The pH below the 7 is consider acidic and above the 7 is basic.
The sodium hydroxide is strongest base because it fully dissociate into ions.
It dissociate to gives the sodium and hydroxyl ions and solution became more basic.
NaOH → Na⁺(aq) + OH⁻(aq)
Its pH is 12. It is also known as caustic soda.
The pH of blood is vary from 7.35 - 7.45. it is slightly alkaline.
The pH of lemon juice is ranging between 2-3.
The pH of tap water is ranging between 6-8.5.
From above given information it can be noticed that lemon juice have lowest pH i.e 2-3. It is acidic, because its pH is less than 7.
We know that each millimeter contains 10⁻³ meters. Writing this as a ratio:
1 mm : 10⁻³ m
We require a conversion from m³ to mm³, so we must take the cube of the ratio we have made:
1 mm³ = (10⁻³)³ m³
Therefore, the conversion used will be:
(1 mm / 10⁻³ m)³
When we multiply by this conversion, we will get:
32 m³ = 32 x 10⁹ mm³
Explanation:
One positive impact of the mining is that the sale of the Bauxite will increase their economic power by bringing in foreign exchange into their economy. This will improve services such as healthcare and infrastructure.
A negative impact is the destruction of the nature preserve and disturbing the ecosystem could lead to a devastating loss in biodiversity. A decrease in biodiversity will increase crop pests and diseases that destroy standing crops, and an increase in the prevalence of diseases in the community.
Able to be hammered or pressed permanently out of shape without breaking or cracking. An example would be hot metal being shaped.
I think they are called Faults.
