This statement lons form because the loss of one or more electrons makes them less stable than their corresponding atoms; this state requires more energy to maintain is FALSE.
- An ion forms when an atom loses or gains one more electrons.
- This loss or gain of electrons causes the ion to gain the stable octet configuration.
- This stable octet configuration requires less energy to maintain than the corresponding atom.
So, since the stable octet configuration of the ion requires less energy than the corresponding atom, the statement is false.
So, the statement lons form because the loss of one or more electrons makes them less stable than their corresponding atoms; this state requires more energy to maintain is FALSE.

To determine the amount of oxygen that is present in the compound, we have to assume that the given compound contains carbon, hydrogen and oxygen only or else we will not be able to determine the answer. We need to convert the moles of the elements given to units of grams by using the atomic mass of these elements. Then, from the total amount of the compound we subtract the masses of the elements. We do as follows:
mass
0.117 mol C ( 12.01 g / 1 mol ) = 1.41 g
0.233 mol H ( 1.01 g / 1 mol ) = 0.24 g
Mass O = 3.50 g - 1.41 g - 0.24 g = 1.85 g O
Moles O = 1.85 g O ( 1 mol / 16 g ) = 0.116 moles O
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
