In an experiment, 3.25 g of Ali are allowed to react with 3.50 g of O2. 4Li + O2 > 2Li2O. Which reactant is the limiting reagent?

Explanation:

4Li        +       O₂    =     2Li₂O.

4 mole       1 mole

3.25 g Li = 3.25 / 7

= .464 moles

3.5 g of O₂ = 3.5 / 32 mole

= .11 mole

.11 mole of O₂ will react with .44 mole of Li as per the equation above

but Li available is .464 which is in excess .

Hence O₂ is in short supply for given mass of Li .

Hence O₂ is the limiting reagent .

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

the answer is b. dilution
