Answer:
N2O4
Explanation:
To obtain the molecular formula of the compound, first, let us calculate the empirical formula for the compound. This is illustrated below:
N = 0.606g
O = 1.390g
Next, we divide the above by their molar masses
N = 0.606/14 = 0.0432
O = 1.390/16 = 0.0869
Next, we divide by the smallest
N = 0.0432/0.0432 = 1
O = 0.0869/0.0432 = 2
The empirical formula is NO2
The molecular formula is given by:
[NO2]n = 92
[14 + (16x2)]n = 92
[14 +32]n = 92
46n = 92
Divide both side by the coefficient of n i.e 46
n = 92/46
n = 2
The molecular formula = [NO2]n = [NO2]2 = N2O4
Glaciers are found in areas where the net accumulation of snow exceeds the melt, therefore they are usually found in areas of high elevation, cold temperatures, and high precipitation.
Geysers are found in areas of shallow crust with high heat flow, such as hot spots.
Explanation:
Le Chatelier's principle states that for a long period of time if a system is at equilibrium and it is subjected to change in concentration, temperature, volume or pressure then the system shifts to a new equilibrium.
This change will partly counter acts the applied change.
Therefore, when heat is added to the system then equilibrium will shift to the side where temperature or heat is reduced again.
For example,
Since heat is added to the system, hence, system will shift to the left side or we can say equilibrium will shift to the backward direction.
This statement would be best characterized by the law of conservation of momentum—choice C.
Answer:
If the electronegativity difference is greater than 2.0, then the bond is ionic.
Explanation:
For ex:
Na has the electronegativity of 0.93
Cl has the electronegativity of 3.16
we subtract 3.16-0.93
We have 2.23 electronegativity difference between Na and Cl
because 2.23 > 2.0
therefore NaCl compound has an ionic bond.
