The prediction of the products and the balanced form of the above incomplete equation is as follows: Ag + Cu(NO3)2 → Cu + Ag(NO3)2 (option D).
<h3>How to balance a chemical reaction?</h3>
According to this question, silver reacts with copper nitrate to form products that were not stated.
However, this reaction is an example of a displacement reaction, hence, silver will displace or replace copper in the compound to form copper and silver nitrate as products. The reaction is given as follows:
Ag + Cu(NO3)2 → Cu + Ag(NO3)2
This chemical reaction is said to be balanced because the number of moles of each atoms on both sides of the equation is the same.

Answer: m Most likely Group2 metals and Group 17 non-ktta
Explanation:
A little more information is needed to be certain, but the likely answer is that X belongs to Group 2 and Y belongs to Group 17. Group 2 metals (Be, Mg, Ca, Sr, Ba, etc.) are all divalent. They gave rive up 2 electrons each to return to a full shell. Group 17 elements (e,g, F, Cl, Br, I, etc.) all require 1 electron to reach a full valence shell. That would make the proportion 1X to 2Y, or XY2. It is possible that a metal outside of Group 2 would also have a valency of 2. Iron(II) forms FeCl2, for example.
Answer:
<h2>Scientists use a wide variety of techniques to monitor volcanoes, including seismographic detection of the earthquakes and tremor that almost always precede eruptions, precise measurements of ground deformation that often accompanies the rise of magma, changes in volcanic gas emissions, and changes in gravity.</h2>
B. Oxygen. Hope this helps.
