I'm supposed to compare the percent composition of gases in the atmosphere at sea level to the percent composition at high altitude.. Would the percents decrease? I don't really understand
explain why a sealed bag of potato chips "puffs out" (increases in volume) if taken from sea level to a high mountain pass. I know this has to do with pressure.. so is it because the higher up you go, the less pressure there is? Thanks!
The most common protein secondary structures (the alpha helix and beta conformation) are stabilized primarily by A. ionic bonds B. hydrogen bonds C. disulfide bonds D. van der Waals interactions E. hydrophobic interactions
Suppose a laboratory has a 26 g sample of polonium-210. The half-life of polonium-210 is about 138 days.?
Just having some trouble with this chemistry problem.. Thanks for help! Toxic carbon monoxide (CO) gas is produced when fossil fuels such as petroleum burn without enough oxygen. The CO can eventually be converted to CO2 in the atmosphere. Automobile catalytic converters are d...
What volume would be occupied at 0°C and 1 atm by 3 mol CO₂(g)? I just might need someone to help me work this out, I would greatly appreciate it! I don't understand this chemistry problem.

a ball is dropped from a height of 10 ft. if the ball's height after t sec is modeled by the following equation h(t)=-16t^2+10. when does the ball hit the ground?
Roses were planted 100 cm apart around a rectangular garden. There were no roses at the corners. They started 1 m from each corner. The garden was 5 m by 3 m. How many roses were planted?
Assume that the LHMP is enclosed in a transparent polymer stucture. a. How will the gases inside LHMP be affected by hot days and cool nights? b. What design features might be incorporated in the LHMP to reduce those heating and cooling effects? I know that gases expand in hea...
