A sample containing 1.50 mol of Ne gas has an initial volume of 11.00 L. What is the final volume, in liters, when a sample of 3.50 mol of Ne is added to the 1.50 mol of Ne gas in the container and pressure and temperature do not change?

answer: mole of the gas

answer: mole of the gasexplanation:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
