Answer
% of C in C2H6= (2×12)/30×100=80%
% of H in C2H6= (3×2)/30×100=20%
Explanation:
2C+3H2-C2H6
nC=12, nH=1, nC2H6=30
2moles of C-1mole of C2H6
3moles of H-1 mole of C2H6
% of C in C2H6= (2×12)/30×100=80%
% of H in C2H6= (3×2)/30×100=20%
The cations has positive charges that are metals while the anions have negative charges that are non-metals. Upon reaction, there is an exchange in charges that are reflected in the subscripts of the atoms. In this case, compound AX2 must have a cation, A belonging to group 2 A with +2 charge and anion, X belonging to Group 7A with -1 charge. Answer is D.
Answer:
Glucose
Explanation:
Glucose, also called dextrose is one of a group of carbohydrates known as simple sugars or monosaccharides. Glucose is derived from the Greek word 'glykys' meaning “sweet”. It has the molecular formula C6H12O6. It is commonly found in fruits and honey and is the major free sugar circulating in the blood of higher animals. It is the source of energy in cell function, and the regulation of its metabolism is of great importance. Molecules of starch, the major energy-reserve of carbohydrate of plants, consist of thousands of linear glucose units. Another major compound composed of glucose is cellulose, which is also linear. Dextrose is the molecule D-glucose.
Glucose is composed of carbon hydrogen and oxygen in a ratio of 1:2:1 as typified by its formula. It is known for its sweet taste. It can be combined with fructose in table sugar.
