Chemistry
1 answer:
ASHA 777 [7]3 years ago
7 0

Answer:

4.12 mol  

Explanation:

Given data:

Moles of LiOH  required = ?

Volume of solution = 4.2 L

Molarity of solution = 0.98 M

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

we will calculate the moles from above given formula.

0.98 M = number of moles / 4.2 L

0.98 M × 4.2 L = number of moles

Number of moles = 0.98 M × 4.2 L

Number of moles = 4.12 mol     (M = mol/L)

How does the vegetation surface type affect the amount of runoff
maxonik [38]

Answer:

<em>The type of vegetation a surface does affect the </em><em>water coming from above to sink in or runoff. </em>

Explanation:

This is how the vegetation affects the runoff:-

The leaves and stems present in the vegetation do not let the water fall directly on the soil and makes the process rather slow which makes the water to get to the ground slowly and sink in properly inside the soil rather than running off.

If the vegetation present is dense with  there was being hairy then also the water would not run out and will get absorbed by the roots letting the soil intact

Every oxygen atom has 8 electrons. what can you learn from the electron configuration of oxygen
-BARSIC- [3]
What you can learn, is since there are 2 in the first ring of electrons, that is full, the other 6 are valence electrons which can bond with others, and want to bond with them to finish the ring of 8 electrons.
