Explain why the pressure in a sealed container of gas decreases when heat is added to the system?
weeeeeb [17]

Answer:

the question is bogus

see explanation

Explanation:

explain why the pressure in a sealed container of gas decreases when heat is added to the system?

when you add heat to the gas molecules in a sealed container, the molecules move faster and the pressure INCREASES!!!

IT DOES NOT DECREASE

PV =nrT

IF THE O THEVOLUME IS FIXED (REIN A SEALED CONTAINER) AND THE  NUMBER OF MOLES n is FIXED, THEN THE PRESSURE IS DIRECTLY PROPORTIONAL THE TEMPERATURE

THE GREATER T, THE GREATER P

Potassium cyanide is a toxic substance, and the median lethal dose depends on the mass of the person or animal that ingests it.

A set of aqueous solutions are prepared containing different acids at the same concentration: acetic acid, chloric acid and hydr
navik [9.2K]

Answer:

The solutions of hydrobromic acid and of chloric acid are the most electrically conductive.

Explanation:

The electrical conductivity of a solution is determined by the concentration of ions in the solution. The acids listed react with water to form ions. In the case of hydrobromic acid, for example, the reaction is as follows:

HBr + H2O >> H3O(+) + Br(-)

Hydrobromic acid and chloric acid are strong acids, meaning the reaction is considered to proceed at 100%. Acetic acid, however, is a weak acid and the reaction with water does not go to completion, so there are less ionic species in the solution of acetic acid, which makes it less electrically conductive.
