A typical recreational scuba diver might fill his or her breathing tank with a mixture of nitrogen (P =136 atm) and oxygen (P = 64 atm). Below is an equilibrium that exists between oxygen and nitrogen gases at 298 K:
N2(g) + O2(g) + 2NO(g); K = 4.1x 10-31.Nitrogen monoxide is a pretty nasty gas that will burn the lungs when inhaled in high enough concentrations. Should the diver be concerned about the toxic gas?

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
