The correct answer is option A, that is, a landfill in the region of nonporous bedrock.
A permanent waste disposal facility where the wastes are put into the ground and covered with a layer of plastic, soil, or both is known a landfill. A secure chemical landfill refers to a landfill developed in the region of nonporous bedrock.
A secure chemical landfill is a prudently engineered depression in the ground or constructed on the top of the ground, signifying a football stadium into which wastes are dumped. The objective is to inhibit any water-related or hydraulic association between the surrounding environment and the wastes, mainly groundwater.
Explanation:
The given data is as follows.
= 3 M,
= ?
= 10 M,
= 10.0 ml
Therefore, calculate the volume of given solution as follows.
=
Now, putting the given values into the above formula as follows.
=
=
= 33.3 ml
or, = 0.033 L (as 1 ml = 0.001 L)
Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.
Molarity = 
3 M = 
mass = 3.96 g
Therefore, we can conclude that mass of NaOH is 3.96 g.
Answer:
Option B
Explanation:
An economics footprint can be described as a measure of biological productivity.
Ecological footprints show a comparison of the rapidness of our resources consumption and waste generation to the rapidness of natural absorbing these wastes and also including our carbon emission.
Thus, one of the characteristics of ecological footprints is a measure of our biological productivity.
Answer is A.. hope this helps:)
When alleles are recombined during sexual reproduction, they can produce dramatically different phenotypes. Thus, sexual reproduction is a major source of variation within many population. Asexual<span> production is when there is one parent that produces offspring that are identical to the parent. Basically a copy of the parents DNA.
Your answer in short is B
