Get the moles. n = m/MM n = 1.222grams / (Na2C2O4 Molar Mass) Molarity = mole / volume = [1.222g / (Na2C2O4 Molar Mass)]/0.500 L.

q = mcT Find the q for water (change in temp should be 100 - 20) q = 200(c)(80) Then solve for the final temp of the iron using -q.

Chemistry(Please help, thank you!!)
Acid- Base titration of a weak-acid. H2S04 is a weak acid. NaOH is a strong base. pH = 14 + log(sqrt)[(M1*M2*Kw)/([M1+M2]*Ka)] M1 = Concentration of Weak Acid. M2 = Concentration of Strong Base. Kw = dissociation constant for water. Ka = dissociation constant for acid. Note: M...

Physics
It must have enough acceleration to overcome the net gravitational force of the solar system. Second part. The rocket will just need enough acceleration to overcome the gravitational force of the sun and the earth. Well, if the earth was moving in orbit you can use centripital...

You should be able to do this yourself. P1V1 = P2V2 P = Pressure V = Volume 1 denotes initial 2 denotes final Source: Boyle's Law
