So, i have missed school around three days out of the week. and in science, we are going over the periodic table, i suppose.. and i have got a sheet in front of me in which i am supposed to "unscramble" 32 words. i honestly have no idea how to correctly spell each, may someone ?

How many moles of air are there in a human lung with a volume of 2.4 l at stp? explain your answer

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

The following questions a24 - a26 relate to 100 ml of 0.0150 m solution of benzoic acid (c6h3cooh). ka(c6h3cooh) = 6.4 x 10^-5. what is the ph of the solution after the addition of 1 x 10^-3 moles of naoh? you may assume no volume change to the solution upon addition of the naoh.
