25 moles of NOCI were placed in a 2.50 L reaction chamber at 427°C. After equilibrium was reached, 1.10 moles of NOCI remained. Calculate the equilibrium constant, Kc, for the reaction 2NOCI(g) + 2NO(g) + Cl2(g).
Select one:
O a. 3.0 x10-4
O b.4.1 X10-9
O c. 18 x10
O d. 14 x10-
O e.5.6 x10-4

How many grams of mgbr2 are needed to produce 75g or metal?

Nuclear decay is the spontaneous decay of one element into a. an x-ray b. a ray of light c. another element

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
