** will mark you brainliest ** when 0.5 g of powdered iron (iii) oxide was added to 100 cm3 of hydrogen peroxide, water and oxygen were produced. iron (iii) oxide was not used up in the reaction. based on the information, which of the following is likely to increase the rate formation of the products? a. replacing the powdered iron oxide with its cubical crystals b. using 150 cm3 of hydrogen peroxide c. removing iron oxide from the reaction mixture d. using 1.0 gram of iron oxide

Its B. Using 150 cm3 of hydrogen peroxide

The answer is B because when you calculate it you will get the same amount of hydrogen peroxide.

Good luck,!

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

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.
