A substance contains 36.1 percent calcium and 63.9 percent chlorine by weight. What is the empirical formula of the given compound?
Weegy: Assume 100 g of the compound is present. This converts the percentages into mass. Then, calculate moles of each element: Ca - -> 36.1 g / 40.08 g/mol = 0.9007 Cl - -> 63.9 g / 35.453 g/mol = 1.802 Next, look for the lowest whole-number ratio. [ We do this by dividing by the smallest value: Ca - -> 0.9007 / 0.9007 = 1 Cl - -> 1.802 / 0.9007 = 2 The empirical formula is CaCl2 ] User: hello Weegy: Yes , are there any additional question from you ?

In a chromatography experiment, chlorophyll pigments are separated using paper. What is the stationary phase in this experiment? User: Which statement best compares the density among the three states of matter? User: Which criteria determine whether a heterogeneous mixture is a colloid or a suspension?
Weegy: Suspensions Suspensions are heterogeneous mixtures from which some of the particles settle with time. Muddy water is a classic suspension, with relatively large solid particles suspended in water. [ Upon standing the solids start to settle to the bottom of the container. In water suspensions the average suspended particle is larger than 100nm, whereas in a solution all particles are less than 1nm. Suspensions are usually quite easy to separate into their components by filtration, with the larger particles being caught in the filter paper. Colloids Colloids are heterogeneous mixtures which do not settle out like suspensions, but are not true solutions either. Modern plastic paint is a typical colloid, with plastic particles less than 100nm but bigger than 1nm. These intermediate sized particles are big enough to scatter light, but small enough to remain suspended in the liquid. Aerosols, glues, jelly, and smoke are all colloids. Colloids generally cannot be filtered and do not settle with time. Dust scattering light from a projector is an example of a solid/gas colloid, albeit very dilute! ] (More)
