Abarometer in a city shows a sudden fall in the mercury level. what type of weather is most likely expected in the city?

The city would most likely expect to get heavy rainfall due to sudden fall in the mercury level in the barometer.

Explanation:

An apparatus, which is utilized to find the atmospheric pressure is known as a barometer. As there is a change in the pressure with the distance above or below the level of the sea, the instrument can also be used to find altitude. There are two prime types of barometers used, these are mercury and aneroid. A sudden fall in the mercury level shows that heavy rain is going to take place.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
