Bacteria and viruses are inactivated by temperatures above 139 ∘C in an autoclave. An autoclave contains steam at 1.00 atm and 1
andrezito [222]
To answer this question, we will use pressure law which states that:
"At constant volume of a fixed mass of gas, the pressure of the gas is directly proportional to the temperature"

This means that:
Pi / Ti = Pf / Tf where:
Pi is the initial pressure = 1 atm
Ti is the initial temperature = 100 + 273 = 373 degree kelvin
Pf is the final pressure that we want to calculate
Tf is the final temperature = 139 + 273 = 412 degree kelvin

Substitute in the equation with the givens to calculate the pressure as follows:
1 / 373 = Pf / 412
Pf = (1/373) * 412 = 1.104557641 atm

Which compound is soluble in water PbS BaS Na2S Fe2S3
Dmitry [639]

Answer:

The answer to your question is Na₂S, if you need to choices the other one is BaS

Explanation:

As a general rule, all the compounds that have sulfur, are insoluble in water, but the are some exceptions.

-Molecules with ammonia

-If the molecule has alkali metals is soluble

-If the molecule has Ca⁺², Sr⁺² and Ba⁺² is soluble in water.

From the compounds given, following the rules, the compound that is soluble in is Na₂S and perhaps BaS.
