Answer:
The answer is the respiratory system
Explanation:
The function of the respiratory system is to move two gases. These two gases are called oxygen and carbon dioxide. Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them.
The correct option is this: BF3 IS SYMMETRICAL WHILE NF3 IS UNSYMMETRICAL.
Symmetry is used in chemistry to explain the structure of chemical substances, that is, it is used to explain how the particles in chemical substances are arranged. In chemistry, molecular symmetry is used to explain the behavior of chemical substances. A chemical substance is said to be symmetrical if its polar bonds are evenly distributed; it is described as unsymmetrical if its bonds are unequally distributed. In the compound BF3, the bond dipoles cancel one another out because the polar bonds are evenly distributed whereas in NF3, the bond dipoles were not able to cancel each other out because of unequal distribution of the polar bonds, the compound has a net dipole moment.
CH3OCH3 and C2H5OH are isomers. They have same molecular formula. But with another formation.
Answer: C2H4
Explanation:
The percentage composition of ethanol ( C2H5OH ) consist of 52.2% Carbon, Hydrogen of 13.0 and 34.8% of Oxygen.
The percentage composition of ethane gas (C2H6) consist of 80.0% carbon and 20.0% hydrogen.
The composition of Ethylene Glycols i.e C2H4(OH)2 is Carbon of 39.7%, 9.7% hydrogen and 51.6% oxygen.
The percent composition of c2h4 is 86% carbon, and 14% hydrogen.
From the information given, the substance with the highest percentage of carbon is C2H4
