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 ... (More)

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 ... (More)
