<h2>Explanation:</h2><h2>2.what do you mean by population growth ?write its any 5 effect on environment</h2>

Population growth is the increase in the number of individuals in a population. -air gets polluted -deforestation -land degardation -natural disaster -water gets pollutedThe terai region extends from the chure range in the north to the border of India in the south.lt covers 17 percent of total land of Nepal .this terai region is mostly flat and plain with alluvial fertile deposited by the rivers . the climate of the reason is hot and wet in summer and cold and dry in winter.Terai also called the granary of Nepal as more than half percent of people of Nepal depend on the vegetation of Terai region. Terai is plain, where more cultivation is possible. Cultivation is impossible in mountain region due to difficult topography and temperate region and even in hilly region with lots of vegetation it's not possible due to slope area. Terai is only the possible region where much cultivation is possible. Different kinds of vegetation, valuable medicinal herbs, important trees, etc. are found in Terai region.

An atom of which of these elements most likely forms an anion? A. AI B. Br C. Ca D. Mg
Papessa [141]
The answer is B. A good way determine this is how far right the element is on the periodic table. The further right the element is, the more electronegative it is meaning it is more willing to accept an electron. This can be explained using the valence electrons and how many need to be added or removed to complete the octet. The further right you are, the easier it is for the element to just gain a few electrons instead of loose a bunch. Noble gases are the exception to this since they don't normally react though.

How does water help us live
SSSSS [86.1K]

Your body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it's important to re-hydrate by drinking fluids and eating foods that contain water.

What is the concentration of H+ ions at a pH = 2?
kari74 [83]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.

What is the concentration of H+ ions at a pH = 2?

<h3>0.01   mol/L  </h3>

What is the concentration of OH– ions at a pH = 2?

<h3>0.000000000001   mol/L   </h3>

What is the ratio of H+ ions to OH– ions at a pH = 2?

<h3> 10,000,000,000 : 1</h3>

Name the following ester molecule:OA. ethyl butanoateB. propyl pentanoateC. methyl heptanoateD. methylpropanoate
disa [49]

Answer

A. ethyl butanoate

Explanation:

Esters are known for their distinctive odors and are commonly used for food aroma and fragrances. The general formula of an ester is RCOOR'.

Esters are formed through reactions between an acid and an alcohol with the elimination of water.

Esters are named as if the alkyl chain from the alcohol is a substituent. No number is assigned to this alkyl chain. This is followed by the name of the parent chain from the carboxylic acid part of the ester with an –e remove and replaced with the ending –oate.

Hence, the name of the given ester is:

A. ethyl butanoate
