Answer:
The answer to your question is: 79.6 L
Explanation:
Data:
n = 60 moles
Pressure = P = 20.0 atm
Temperature = T = 50°C
Volume = V = ?
Convert temperature to Kelvin
°K = 273 + 50
°K = 323
Formula (ideal gas law)
PV = nRT solve for V
V = nRT / P
V = (60)(0.08206)(323) / 20 Substitution
V = 1590.32 /20
V = 79.6 L
An isotope is the vary of neutrons in an element, causing its atomic mass to change. While an ion is a charged atom that bonds to be stable.

Explanation:
4. limestone heat lime + carbon dioxide
The reactants in this expression above is limestone
The products of the reaction is carbon dioxide and lime
Reactant is the species that gives the product and it is usually found on the left hand side of the expression.
The product is the substance on the right hand side of the expression that forms through the experiment.
Heat is used to facilitate the reaction.
5. An exothermic reaction is a reaction in which heat is given off.
An endothermic reaction is a reaction in which heat is absorbed in the process.
An exothermic reaction is always warmer after the reaction whereas an endothermic reaction is colder at the end of the reaction.
6. Sodium salicylate is made from carbon dioxide and sodium phenoxide.
The reactants are:
Carbon dioxide and sodium phenoxide
The product is:
Sodium salicylate
