Answer:
3.16×10⁹ pL
Explanation:
Given data:
Volume in mL = 3.16
Volume in picoliters = ?
Solution:
Picoliter and milliliters are units of volume. Milliliter is greater unit than picoliter.
1 mL = 10⁹ pL
Now we will convert the 3.16 mL into pL.
3.16 mL × 10⁹ pL/ 1 mL
3.16×10⁹ pL
Answer:
- is reused and recycled
- can dissolve more substances than any other liquid
Explanation:
Earth water is reused and recycles in the form of the water cycle (hydrological cycle). In this cycle, water from the earth surface evaporates in the atmosphere, cool and condense into cloud or snow and fall to the earth surface.
As a universal solvent, water can dissolve more substances than any other liquid. The polar arrangement of oxygen and hydrogen atom in the water molecules makes it excellent salt.
On Earth, ~2.5% is a freshwater whereas 97.5% is salt water. The pH of water differs for surface and salt water, i.e. neutral to alkaline respectively. Water molecules attract to other water molecules better than the other substances. Therefore, other options are incorrect.
It has to be moist in the grass
Answer:
Yes
Explanation:
It was less clay. Which causes less area for impact.
Option (a) is correct.
A reducing agent is the one which loses electrons to other substance and an oxidizing agent is one which accepts electrons.
Here, In
![CrO_{3}](https://tex.z-dn.net/?f=%20CrO_%7B3%7D%20)
, Cr has oxidation number 6+ in the L.H.S of the equation, but on R.H.S its oxidation number is 0 i.e. it Cr has gained electrons such that total charge is 0.
And the oxidation state of Al in the left-hand side of equation is 0 and in right-hand side, it is +6.i.e. it has donated its electrons to Cr.
Hence, Cr is the oxidizing agent and Al is the reducing agent.
