If 43.0 grams of Sodium Carbonate reacts with 72.0 grams of Lead (IV) Chloride to yield Sodium Chloride and Lead (IV) Carbonate. (Write the equation, balance it and then solve the problem) A. How many grams of Lead (IV) Carbonate is produced
B. What is the limiting reagent
C. How many grams of the reagent in excess is left
D. If the % Yield is 54% then how many grams of Lead (IV) Carbonate is produced.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

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.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
