1. Balance the following reaction equation. Note: in Organic Chemistry, a standard balanced reaction equation not only balances all the elements on the left vs. the right, but also shows molecular structures. Formulas such as "CHO." are normally not used, because they don't identify a specific isomer. conc. HCI 2. Complete the following...

2. In this problem, we will prove the following result: If G is a group of order 35, then G is isomorphic to Zg We will proceed by contradiction, so throughout the following questions, assume that G is a group of order 35 that is not cyclic. Most of these questions can he solved independently I. Show that every element of G except the identity has order 5 or 7. Let...

Please answer al three questions. Thank you!!
I Review I Constants I Periodic Table When a chemical reaction occurs, atoms rearrange to form new compounds, but no new atoms are created nor are any destroyed. This concept is called conservation of Part A mass. Mass conservation can be seen in a balanced chemical equation, where the numbers of each kind of atom are the same on both sides of the reaction arrow. The figure (Figure 1) shows the reaction of...
