When zinc or aluminum was allowed to react with the copper sulfate , what was the limiting reagen?

musickatia [10]

Usually it is the CuSO4 that is the limiting reagent.

if all of the color of the solution was gone, but there was still some zinc metal mixed in with the copper metal produced, then Zn is the excess reagent 

f all of the color of the solution was not gone, but there was no zinc metal left in with the blue copper solution , then Zn is the limiting reagent Hope this helps.

It's actually Science but I didn't find it.

Answer:

Forces acting on an object may be balanced or unbalanced. When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object does not change. When the forces acting on an object are unbalanced, they do not cancel out one another. An unbalanced force acting on an object results in the object’s motion changing. The object may change its speed (speed up or slow down), or it may change its direction. Friction is a force that resists the motion or the tendency toward motion between two objects in contact with each other. Gravity is a force that pulls objects toward one another. For example, Earth pulls all objects toward it.

Consider the following reaction: 3Fe(s) + 4H₂O(g) ➞ Fe₃O₄(s) + 4H₂(g). To answer the following question: "How many moles of hot

UkoKoshka [18]

X moles of hot water vapor(H2O) * 1 mol Fe3O4 / 4 mol H2O * 233.55g Fe3O4 / 1 mol = 275 g

Solve the equation

x = 4.71 mol of hot water vapor (steam)

HELP NOW BRAINLIST AND 15 POINTS!!!!! I'M TIMIED!!!!!

Answer:

Explanation:

1 = The given chemical reaction does not follow the law of conservation of mass because,

2 = Four hydrogen atoms are present in reactant side and two hydrogen atoms are present in product side.

3 = 1 ) The given chemical reaction does not follow the law of conservation of mass because,

CH₄ + O₂ → CO₂ + H₂O

16 g + 32 g 44 g + 18 g

48 g 62 g

Law of conservation of mass:

This law stated that mass can not be created or destroyed in chemical reaction. It just changed from one to another form.

For example:

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O

28 g + 96 g = 88 g + 36 g

124 g = 124 g
