Please help me. On a heating of solid W, a residue was formed which was orange when hot and turned yellow on cooling. The lime water formed a white precipitate I) Identify the cation and anion in Solid W II) Write an equation for the formation of white precipitate in lime water.​

Amixture with the same composition throughout is!

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.

In an exothermic reaction at equilibrium, what is the effect of lowering the temperature? a. the reaction makes more products. b. the reaction makes more reactants. c. the reaction is unchanged.
