A miner finds a sample of rock and is convinced it contains
gold. He looks up the density of gold and discovers gold has a density
19 g/cm^3, whilst ‘fool gold’ has a density of 5 g/cm^3. The mass of
his sample is 5.5kg and the volume of water is displaced by
it's 300cm3.
a)
Calculate the density of the sample in g/cm^3.

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 1260

7*5*36= 1260 it's all about multiplying

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
