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).

Physical properties of reactants: Physical properties of products: 12.
dolphi86 [110]

Answer: The reactants are baking soda and vinegar. Baking soda is a white powder, and vinegar is a clear liquid. The products of this reaction are carbon dioxide, water, and sodium acetate. Carbon dioxide is a colorless gas, water is a colorless liquid, and sodium acetate is a white crystalline powder.

A chemical change can be seen in how the molecular formulas of the products are different from the reactants, since the reactants have chemically changed into completely different molecules.

Hope this helps

How many moles of methane (CH4) are in 7.31 x 10^25 molecules
Ivan

molar mass of methane CH4

= C + 4 H  

= 12.0 + 4 x 1.008

= 12.0 +  4.032

= 16.042g/mol

7.31 x 10^25 molecules x <u>             1 mole  CH4    </u>  = 121.43 moles

                                       6.02 x 10^23 CH4 molecules

121.43 moles CH4 are present.

HELP!!!!! NO SPAM!!!!!!!!!!!!!!!!!
Lisa [10]

Answer:

Explanation: S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O In the above equation how many moles of water can be made when 115.3 grams of HNO3 are consumed? Round your answer to the nearest tenth. If you answer is a whole number like 4, report the answer as 4.0 Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.: Element Molar Mass Hydrogen 1 Nitrogen 14 Sulfur 32 Oxygen 16...

Hope it helps..!!
