How many particles can be stored in a 4.0 L container at room temperature (23 C) and standard atmospheric pressure (101.3 kPa)? 6.1 moles
0.16 moles
2.1 moles
0.47 moles

0.16 moles

Further explanation

There are 2 conditions that are usually used as a reference in chemical calculations (mainly for determining the volume per mole of gas or the molar volume), namely:

1. Standard Conditions

stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.

2 Room Condition

stated by RTP (Room Temperature and Pressure). Vm in this condition = 24.4 liters / mol

so for 4 L :

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
