Answer:
Assuming the reaction you are referring to is the following:
AgNO3 + Cu --> Cu(NO3)2 + Ag
First, we should balance the reaction:
2 AgNO3 + Cu --> Cu(NO3)2 + 2 Ag
Now we carry out dimensional analysis, taking into account the molar ratios of different species as given in the balanced reaction and molar masses (which we can look up in the periodic table).
We begin with what we know, which is that we have 16.0 g Cu reacting and work our way toward the quantity that we would like to calculate, namely moles of Ag.
16.0 g Cu x 1 mol Cu x 2 mol Ag = 0.504 mol Ag
63.5 g Cu 1 mol Cu
Answer:
mass = 2.65 [nearest hundredth].
Explanation:
Mass = Density / Volume
mass = 1000 / 376.8
mass = 2.653927813163.. ≈ 2.65
Answer:
A. X is an element or a compound while Y is a mixture
Boyles law is P1V1=P2V2 where P is pressure and V is volume so the answer is pressure and volume
Answer:
the outer core is important because the outer core is responsible for earth's magnetic field which protects earth from harmful particles that comes from sun and also contains some natural metal like nikle and iron.
