Answer:
The products are Calcium bromide and Iodine.
Explanation:
According to Group 7 (or Group 17) in the periodic table, as it goes down the group, the less reacrive it is, so <u>b</u><u>r</u><u>o</u><u>m</u><u>i</u><u>n</u><u>e</u><u> </u><u>i</u><u>s</u><u> </u><u>r</u><u>e</u><u>a</u><u>c</u><u>t</u><u>i</u><u>v</u><u>e</u><u> </u><u>t</u><u>h</u><u>a</u><u>n</u><u> </u><u>i</u><u>o</u><u>d</u><u>i</u><u>n</u><u>e</u><u> </u><u>a</u><u>n</u><u>d</u><u> </u><u>w</u><u>i</u><u>l</u><u>l</u><u> </u><u>displace iodine from calcium</u>.
Bromine + Calcium iodide → Calcium bromide + iodine
Answer:
I would say that it is the bond called complementary hydrogen bonds
Explanation:
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
The answer should be (D) endothermic reaction.
Reason : - Reactions in which energy is absorbed are called endothermic reactions. In your provided question, 150 kcal energy is being <u>absorbed</u>, and thus, we can say that it is an endothermic reaction.
Rust does not have the properties to catch onto flames. However, if you light it on fire, then it would probably catch in flames but not instantly and will not continue to burn unless you have soaked it in oil or flammable object or substance. :) Hope this helps!
