HELP.....From the information presented in the activity series of metals below (4 metals included), answer the following questio
san4es73 [151]

Answer:

a)there would be no reaction

Explanation:

The activity series of metals has many functions. The one applicable to this problem is that it can be used to determine whether a reaction will occur or not. Also, based on the positions of metals in the series, we can know how reactive a metal is compared to another.

In a single displacement reaction, a metal replaces another metal based on their position on the activity series. Metals that are higher in the series are generally more reactive than others below them and so will displace them.

 

Would aluminum replace magnesium to form a new compound or would there be no reaction?

Magnesium is higher than aluminum in the activity series. Therefore it is more reactive than aluminum. No reaction will occur.

How does the amount of water in a glass affect the pitch of the sound it produces?
Mrac [35]

Answer:

The glasses with different amounts of water make different sounds. ... This is because the empty glass only has air around it, so the glass vibrates quickly when it is hit, causing the high pitch sound. The glass full of water causes the glass to vibrate slower, and the sound you hear is at a lower pitch.
