The student's lab manual says to mix 50 ml of his 2.0 m cacl2 solution with 50 ml of a 3.0 m aqueous solution of sodium carbonate(na2co3) a. write a balanced equation to show the reaction. include state symbols b. what kind of reaction is this? c. what is the limiting reagent? d. how many grams of precipitate should he get? e. if he got 8.29 of product, what is his percent yield?

output?

explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
