Answer:
A. The ratio of the element in glucose is different than in ethanol
Explanation:
The compounds given are;
Glucose C₆H₁₂O₆
Ethanol C₂H₆O
The two compounds given are different from one another. But they have the same elemental composition.
Ethanol is made up of Carbon, hydrogen and Oxygen and so also, Glucose
Now,
The number of atoms in both compounds are different;
Number of atoms
C H O
Glucose 6 12 6
Ethanol 2 6 1
Answer:
The half-life of a radioisotope describes the amount of time it takes for said isotope to decay to one-half the original amount present in the sample.
Nitrogen-13, because it has a half-life of ten minutes, will experience two half-lives over the course of the twenty minute period. This means that 25% of the isotope will remain after this.
0.25 x 128mg = 32mg
32mg of Nitrogen-13 will remain after 20 minutes.
Compounds are not formed by accepting electrons. Number 1 and 3 are correct.
