CALCULUS
I'm currently on the same question after spending over 2 hours on it... What did you get?

Chemistry
consider the following reaction: 2CH3OH(g) yields 2CH4(g) + O2(g) change in enthalpy= 252.8kJ How many kilojoules of heat are released when 38.4 g of CH_4 g) reacts completely with O2 (g) to form CH3OH (g) at constant pressure?

geometry
how long is a stage that is 6 meters wide with an area of 48 sq meters?

geom/trig
i believe that you set it up like cos(x)= a/h a= 11 feet h= 40 feet then you take the inverse cos of 11/40

Chemistry
yes all of these parts are derived from the same problem How many kilojoules of heat are released when 38.4 g of CH4 (g) reacts completely with O2 (g) to form CH3OH (g) at constant pressure?

Chemistry
For a given sample of CH3OH, the enthalpy change during the reaction is 82.6 kJ. How many grams of methane gas are produced?

Chemistry
consider the following reaction: 2CH3OH(g) yields 2CH4(g) + O2(g) change in enthalpy= 252.8kJ Calculate the amount of heat transferred when 26.0 g of {\rm CH_3OH} (g) is decomposed by this reaction at constant pressure.

CHEMISTRY
which of the following represent a buffer system? A.) NaOH and NaBr B.) HF and NaF C.) HC2H3O2 and C12H22O11 D.) HCl and KOH

CHEMISTRY
write the conjugate acid for the following: A.) NO3- = B.) HPO4^2- = C.) Br- = D.) S2- =

chemistry
write the conjugate base for the following: A.) HCN= B.) HPO4^2- = C.) NH4+ = D.) HC2H3O2=
