How many moles of oxygen must be placed in a 3. 00 L container to exert a pressure of 2. 00 atm at 25. 0°C? Which variables are given? pressure volume temperature moles.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
