Why might it be important to know the empirical formula of different compounds?
Question- A mixture consisting of 0.150 M N2(g) and 0.659 M H2(g) reacts and then reaches equilibrium according to the equation: N2(g) + 3H2(g) 2NH3(g) At equilibrium, the concentration of ammonia is 0.153 M. Calculate the concentration (molarity)..
a family heats their house with propane gas. the gas companyreports that for an average home it takes 41.589 kj of heat
How much heat is liberated at constant pressure if .889 g of calcium carbanate reacts with 43.9 ml of .756 M hydrochloric.
Concentration of the five standard solutions for the reaction
How much heat must be applied to a 18.3 g sample of iron (s=0.449J/(g x *C) in order to raise its temperature from 23.8*C to 356.6*C
The major reason that antiparallel beta-stranded protein structures are more stable than parallel beta-stranded structures is that
a peanut butter sandwich provides about 1.6 103 kj of energy. a typical adult uses about 95 kcalhr of energy while
0.375 g of a monoprotic acid mm 245 gmol is dissolved in water to produce 25.0 ml of a solution with ph 3.28.
For the formation of BHT from p-cresol, State a balanced mechanism and define why the new alkyl groups end up adjacent to the hydroxyl group.
A tanker truck carrying 6.05×103 of concentrated sulfuric acid solution tips over and spills its load. The sulfuric acid solution is 95.0 by mass and has a density of 1.84 Sodium carbonate (NaCO3) is used to neutralize the sulfuric acid spill.
How many mL of 0.0221 M KMnO4 would it take to titrate a 0.5255 g sample of K3Fe(Ox)3? How could the results of your titration be used to determine if the sample was actually a mixture of K3Fe(Ox)3 and K4Fe(Ox)3
Calculate concentrations of OH- and the pH of each basic solution. Since NaOH donates on OH- ion for each NaOH molecule, the OH- concentration is equivalent to the NaOH molarity. The pOH is calculated as -log[OH-] and the pH is calculated as 14-pO..
