A student collected the data shown in the table below during an experiment. Liquid Characteristics
Liquid Characteristics
Boiling Point Freezing Point Color Toxicity
Mercury 357 °C −39 °C shiny silver gray hazardous if tube is broken
Alcohol 78 °C −115 °C colorless relatively non-hazardous

Based on the data, which of the following conclusions can be made about the use of mercury and alcohol thermometers?
An alcohol thermometer can easily measure the boiling point of a colorless liquid that boils at 100 °C.
A mercury thermometer can easily measure the boiling point of a colorless liquid that boils at 82 °C.
A mercury thermometer can easily measure the freezing point of a colorless liquid that freezes at −50 °C.
An alcohol thermometer can easily measure the freezing point of a colorless liquid that freezes at −110 °C.

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

i believe the answer is true.
