A container with a volume of 25.5L holds 1.050mol of oxygen gas (O2), whose molar mass is 31.998g mol. What is the volume if 7.21g of oxygen gas is removed from the container, assuming the pressure and temperature remain constant

Type the letter that represents the correct location for each particle type below.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
