Whether an element is classified as a major or as a trace mineral is determined by "<span>the amounts daily required by the body".

</span>

Calcium, magnesium, phosphorus, potassium, chloride and sulfur are all examples of the major minerals and these are the minerals a body needs in large quantity as opposed to include iron, copper, zinc, manganese, fluoride, selenium and cobalt, which are all trace minerals and are needed in very little quantity.

<h2>Element Trace Mineral is Determination</h2>

Whether an element is classified as a major or as a trace mineral is determined by the amounts needed daily by the body. Species need minerals in varying amounts, but commonly required plant trace elements such as copper (Cu), Boron (B), Zinc (Zn), Manganese (Mn) and Molybdenum (Mo).

Animals require Manganese (Mn), iodine (I) and cobalt (Co). Human requires trace minerals in small amounts such as iron (Fe), iodine (I), fluoride (F), copper (Cu), Zinc (Zn), Chromium (Cr), Selenium (Se), Manganese (Mn) and Molybdenum (Mo).

Some refrigerants used in air conditioners have been associated with _____. smog destruction of the ozone layer thermal pollutio
MrRa [10]

Answer: Destruction of the ozone

Explanation: Some of the he most common refrigerants used for air conditioning is chloroflurocarbons and  hydroflurocarbon that can deplete the ozone layer that is a protective covering.

This covering filters the harmful rays of the sun that is harmful for the human beings and animals on the earth. The coolants contains chlorine which impacts the ozone and cause depletion.

A sample of sulfur dioxide (SO2) is initially at a temperature of
creativ13 [48]

Answer:

874.89 mmHg

Explanation:

Using the combined gas law equation as follows:

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (mmHg)

P2 = final pressure (mmHg)

V1 = initial volume (L)

V2 = final volume (L)

T1 = initial temperature (K)

T2 = final temperature (K)

Based on the information provided in this question;

P1 = 950 mm Hg

P2 = ?

V1 = 25 L

V2 = 30 L

T1 = 155°C = 155 + 273 = 428K

T2 = 200°C = 200 + 273 = 473K

Using P1V1/T1 = P2V2/T2

950 × 25/428 = P2 × 30/473

23750/428 = 30P2/473

55.49 = 0.063P2

P2 = 55.49 ÷ 0.063

P2 = 874.89 mmHg

when the pressure that a gas exerts on a sealed container changes from ____ atm to 2.64 atm, the temperature changes from 315 K
mel-nik [20]

Answer:

1.75 atm

Explanation:

When the pressure that a gas exerts on a sealed container changes from 1.75 atm to 2.64 atm, the temperature changes from 315 K to 475 K.

(2.64 atm) x (315 K / 475 K) = 1.75 atm

The pressure and temperature of a gas in a sealed container are directly proportional. An increase in temperature would imply that the pressure also increased.
