The reaction of iron (III) metal with a solution of copper (II) sulfate releases iron ions into the solution through a single displacement reaction. 1. What mass of iron (in grams) is required to remove all the copper ions from a 150mL of 0.100 mol/L solution of copper (II) sulfate?
2. Determine the moles of iron ions produced in this reaction.
3. Name a soluble compound that could be added to precipitate all of the iron ions from the solution.
4. What mass of the soluble compound from part (c) is required to precipitate all of the iron ions you determined in part (b)? Give your final answer in grams.

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

hi my dude or dudette

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
