I'm so sorry I took long, I'm answering answer after answer :)
Not sure if this is helpful :)
I know these are things in order for an animal to be endangered, but just pick answer that's not these I guess? "Which of the following"
The answer is a. H+ and H2O. For a half-reaction in acidic solutions, elements that are not hydrogen and oxygen are balanced first. Then we add H2O to balance oxygen atoms and we add H+ to balance the hydrogen atoms. We do the same steps for basic solutions, but we also add hydroxide ions OH- in the latter part.
Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged).
Answer:
C2H4
Explanation:
The image attached shows a detailed solution of the above problem. The empirical formula shows the ratio of the atoms of each element present.
