What is the spcific heat (J/kgK) and density (kg/m3) of Linen fiber? I'm testing the thermal diffusivity of nonconductive fibers and need the specific heat and density to figure out the thermal diffusivity.
Interstellar space can be considered as having 10 molecules of hydrogen per cubic centimeter and an average temperature of 2.7 K.
Nitric acid is a component of acid rain that forms when gaseous nitrogen dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous nitric acid. write a balanced chemical equation for this reaction
allowed to expand adiabatically against constant Pext = 10 atm. Compute the final T, ?U, and ?H for this process. Use Cv = 20.8 J/mol*K and assume the gas is ideal.
you purchase a cup of coffee, but, at 98.4 degrees C, it is too hot. You add 45.5 g of ice that is -2.2 degrees C to the 248ml of coffee. What is the final temperature of the coffee?
Write the molecular and net ionic equations for the reaction in aqueous solution of sodium sulfide and sulfuric acid. Explain why the reaction goes to completion.
how many enantiomeric pairs are possible for a monobromo derivative of isopentane?
At a given temperature, 1.18 atm of F2 and 5.91 atm of Br2 are mixed and allowed to come to equilibrium. The equilibrium pressure of BrF is found to be 1.044 atm. Calculate Kp for the reaction at this temperature. F2(g) + Br2(g) 2 BrF(g)
A 2.0 mole sample of the compound K2[Pt(CN)4] is dissolved in water. How many total moles of ions will the solution contain?
Why does surface complex formation with a weak acid lead to a relative maximum in the extent of surface complex formation (adsorption) at a pH which is usually near the value of -log acidity constant of the weak acid (pKHA)
what volume of 0.100 m naoh is required to precipitate all of the nickel (II) ion from 150.0 ml of a 0.251 M solution of Ni(NO3)2
One way to approach the problem is to imagine the reaction proceeds to equilibrium by first going 100% to completion and then backing up a little
The equilibrium constant (Kc) for the reaction shown below is 4.17 10-34 at 25°C. 2 HCl(g) reverse reaction arrow H2(g) + Cl2(g) What is the equilibrium constant for the following reaction at the same temperature. H2(g) + Cl2(g) reverse reaction a..
