Determine the [OH−] , Ph, and POH of a solution with a [H+] of 0. 00017 m at 25 °C.
tino4ka555 [31]

Main Answer:

Given

pH = -log[H+]

= -log[0.00017]

= 3.769

We know that

pW = pH + pOH

and pW =14

pOH = 14-pH

=14-3.769

=10.231

According to the definition

pOH = -log[OH-]

10.231 = log[OH-]-1

[OH-]= 5.87 x 10-11

Explanation:

What is pH?

pH is defined as the concentration of H+ ion in the solution. If the pH value is less than 7, then the solution will be acidic. If the pH value is greater than 7, then the solution will be basic.

Which of the following is NOT a way that reducing biodiversity directly impacts humans?
Zepler [3.9K]

C. Fewer habitats for wild animals to live in

Explanation:

Biodiversity does not directly impact humans in that there are fewer habitats for wild animals to live in. This is a direct impact on animals and not humans.

Biodiversity is the variation of life forms in an area. It is measured by the ability of the ecosystem to sustain different life forms and keep their interaction with the environment.

It helps to maintain and sustain life.

To humans, reducing biodiversity;

  • reduces the potential of medicine derived from other organisms. When their habitat is lost, we lose them.
  • fewer ecosystems to appreciate for beauty and recreation. It leads to loss of the ecosystem.
  • fewer wild food species for humans to eat.

Loss of habitat directly affects wild animals and not man.

34. Explain how dimensional analysis is used to solve<br> problems.
alisha [4.7K]

Answer: By understanding conversion factors and how they are related to each other

Explanation:

Dimensional Analysis is a step by step approach to solving problems in Physics, Chemistry , and Mathematics. It involves having a clear knowledge and understanding to be able to convert a given unit to another in the same dimension using  conversion factors and knowing how they are related to each other.

For instance, In Chemistry, we want to Convert 120mL to L.(note that ml stands for millilitres and ;L stands for litres)

Or first approach will be to write out the conversion factor related to our problem which is

1000ml =1L

such that 120ml = (we cross multiply))

giving us  120ml x 1L/1000ml =0.12L

This same process is applied to convert any type of dimensional analysis problems be it physics or mathematics.

How do nuclear fusion and combustion relate?
RUDIKE [14]

Answer:The key to remember is that carbon combustion requires oxygen. As soon as there is no oxygen left, carbon combustion stops. In nuclear fusion, the nuclei of atoms are fused together to make new, bigger nuclei.
