Answer:
Atom may be defined as the smallest particle of an element which does not exist free in nature but takes part directly in chemical combinations.
Atom of any element is represented by the symbol of that element. For example, hydrogen atom is represented by H, sodium atom is represented by Na, etc.
Molecule may be defined as the smallest particle of an element or compound which exists free in nature but does not participate directly in chemical combinations.
Molecule of any substance is represented by their molecular formula. For example, water molecule is represented by H2O. It tells that each water molecule contains two atoms of hydrogen and one atom of oxygen.
% H = 100 - ( 52.14 + 34.73 )=13.13 %
<span>assume 100 g of this compound </span>
<span>mass H = 13.13 g </span>
<span>moles H = 13.13 g / 1.008 g/mol=13 </span>
<span>mass C = 52.14 g </span>
<span>moles C = 52.14 g/ / 12.011 g/mol=4 </span>
<span>mass O = 34.73 g </span>
<span>moles O = 34.73 g/ 15.999 g/mol=2 </span>
<span>the empirical formula is C4H13O2</span>
Answer:
Explanation:
Using the necessary reagents to faciliate the synthesis of the organic compounds as shown in the attached file.
Answer:
It kinda is
Explanation:
The school system isn't very affective on the young adolcent minds, the crime rate is very high (indicating poverty rates) some drug smmuglers are based in Haiti, and half the city is destroyed from either people or the environment.
<span>If one of the impurities in diesel fuel has the formula c2h6s, then the products that will form would be carbon dioxide, water and sulfur dioxide. The balanced chemical reaction would be as follows:
</span>C2H6S(l)<span> + 9/2O2(g) = 2CO2(g) + 3H2O(v) + SO2(g)
</span>
Hope this answers the question.
