PLEASE HELP! (IM GIVING BRAINLIEST) Iron is a transition metal and, as such, can form two types of "oxide" salt compounds, FeO a
belka [17]

Answer:

See explanation

Explanation:

Iron exhibits two stable oxidation states, +2 and +3 states. The difference between FeO and Fe2O3 is that, in FeO, Fe is in the +2 oxidation state while in Fe2O3, Fe is in the +3 oxidation state

In FeO, iron looses two electrons which are gained by oxygen as follows;

Fe^2+ + O^2- -----> FeO

In Fe2O3, Fe looses six electrons while oxygen has gained six electrons as shown;

2Fe^3+ + 3O^2- ------>Fe2O3

In terms of newtons 3rd law of motion desribe this picture.
KIM [24]
Newton's third law (for every action, there is an equal and opposite reaction) means that in every interaction (in this case, that of the objects in the image), there is a pair of forces acting on the two interacting objects. <span>When you sit on a chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. This is embodied in the image by the two objects exerting force on each other (indicated by the arrows).</span><span>

How many grams are in 8.2 x 1022 molecules of N216?
hoa [83]

Answer:

N2I6 = 789 g

N2I6 = 8.2x1022 molecules N2I6 x 1 mole/6.02x1023 molecules = 1.36x10-1 moles = 0.136 moles

N2I6=0.136molesx789g/mole=107g=110g

2Na3N3 -&gt; 2Na + 3N2<br><br> if 0.58 mol if NaN3 reacts, what mass of nitrogen would result
Ronch [10]

Answer:

                      Mass = 24.36 g of N₂

Explanation:

                   The balance chemical equation for the decomposition of NaNO₃ is as follow;

                                           2 NaN₃ → 2 Na + 3 N₂

Step 1: Find moles of N₂ as;

According to equation,

                 2 moles of NaNO₃ produces  =  3 moles of N₂

So,

              0.58 moles of NaNO₃ will produce  =  X moles of N₂

Solving for X,

                      X = 3 mol × 0.58 mol / 2 mol

                      X = 0.87 mol of N₂

Step 2: Calculate mass of N₂ as,

Mass = Moles × M.Mass

Mass = 0.87 mol × 28.01 g/mol

Mass = 24.36 g of N₂
