Molar mass of N = 14 g/molMolar mass of O2 = 32 g/molAdding both masses = 46 g/molActual molar mass/ Empirical molar mass = 138.02 / 46 = 3Now multiplying this co effecient with empirical fomula NO2 = 3(NO2) = N3O6So according to above explanation,D) N3O6, is the correct answer.

Answer:
C
Explanation:
The high specific heat capacity of water means that it takes much more energy to raise the temperatures of water by one (1) degree than land. This means that on a hot sunny day, land temperatures would increase dramatically while ocean temperatures would only rise slightly. Conversely, at night, the land cools rapidly while oceans cool slowly hence the temperatures drop slightly.
True.
The sodium atom becomes a positive ion and the chlorine atom becomes a negative charge because the sodium atom loss an electron and the chlorine atom gained an electron.
Answer:
B. City B
Explanation:
From the weather chart, you can see that rain is indicated by the dot(.) sign. One dot means light rain and two dots mean steady light rain. The circle shading will show how much cloud in the city, ranging from no cloud(white circle), half covered (half black circle) and completely covered(black circle).
City A has neither cloud nor rain.
City B is completely covered by cloud and have steady light rain.
City C is half-covered with cloud, without rain.
