Please help, this is timed. Which refers to the area on the thermometer marked with the letter A? Look at the Diagram. a-scale
b-bulb
c-mercury strip
d-number line

What substance has a mass of 9.5g and volume of 2.1cm^3

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.

Hey, could someone me answer this? much appreciated!
