Determine whether each of the following compounds is soluble or insoluble:

Calculate the percent yield when 0.631 g of precipitate is collected from the reaction of 35.0 ml of 0.100 m silver nitrate and 45.0 ml of 0.0800 v so … dium bromide.

Gaseous nitrogen dioxide dissolved in warm liquid water to form hno3 and gaseous nitrogen monoxide enter a balanced equation for this reaction

What kind of solid tends to have the lowest melting points? o a. solids made of ions o b. solids made of molecules o c. solids made of atoms o d. soli … ds made of metals

science students are planning an investigation to collect data that they 1 point can use to predict the weather. the students decide to do an experi … ment with condensation. their goal is to see how much humidity, or moisture, is in the air each day, which will allow them to predict if it will rain. to set up their investigation, they need a thermometer, a tin can, water, and ice cubes. they perform the experiment outside, placing water in the can, along with the thermometer. the water and the can start out at the same temperature as the air, but the students watch the water and can temperature decrease as they add ice cubes into the can

Given the following reaction, how many grams of na2so4 will be formed from 200.0g of naoh? 2 naoh+h2so4 + 2 h2o + na2so4

A student titrates 60.0 ml of a nitric acid solution to the equivalence point with 42.0 ml of a 0.30 m sodium hydroxide solution. phenolphthalein is u … sed as an indicator. when the equivalence point is reach the indicator color change remains and the student stops titrating. after titrating to the equivalence point, what is the concentration of the nitric acid solution?

How do we know that sunspots are associated with the sun's magnetic field?

Suppose you have two liquids that are soluble in each other: liquid a, with a density of 1.00 g/ml and liquid b with a density of 1.45 g/ml. you take … 15.0 ml of liquid a and 35.0 ml of liquid b. you combine them and stir well so they are thoroughly mixed. calculate the approximate density of the resulting mixture, assuming the final volume is 50.0 ml.

Draw the missing intermediate and add curved arrows for the production of phenylethyne by the double dehydrohalogenation of 2,2-dibromoethylbenzene. n … ote that, although stereochemistry is not graded, it is an important part of the mechanism.

A sodium/potassium pump is a neurotransmitter found in the cellular membrane of your cells where sodium and potassium ions pass between the interior a … nd exterior cells. suppose that each pump requires equal proportions of sodium and potassium ions. if the 5 food items from question 1 were your only source of these electrolytes in a day, which would be the limiting reagent that would prevent these pumps from working? explain your answer qualitatively and quantitatively.
