A stationary front doesn't move at all, where warm and cold fronts do.
Answer:
Explanation:
All the gases at the same temperature and mass have the same average kinetic energy.
If the masses were different, then the different gases will have different velocities. If the temperature was higher then there would be a greater motion, if the temperature was lower, then there would be less motion.

To find the empirical formula you need the relative atomic mass of each element!
Li = 6.9
C = 12
O = 16
You can simply change the percentages into full grams
Li = 18.8g
C = 16.3g
O = 64.9
Then you use this to find the Number of moles = amount in grams / atomic mass
Li = 18.8 ÷ 6.9 = 2.7246
C = 16.3 ÷ 12 = 1.3583
O = 64.9 ÷ 16 = 4.0562
Then divide each number of moles by the smallest value:
Li = 2.7246 ÷ 1.3583 = 2.0
C = 1.3583 ÷ 1.3583 = 1
O = 4.0562 ÷ 1.3583 = 2.9 ≈ 3
So that means that there are 2 Li, 1 C, and 3 O
Empirical formula would be:
Li₂CO₃
Hope this helps!
As we know Sodium belongs to Group I metals and it has a tendency too lose one electron and obtain noble gas configuration (Stable Configuration). On the other hand chlorine belongs to Group VII elements (Halogens) and it tends to gain one electron and attain noble gas configuration.
So, sodium attains +1 charge and chlorine attains -1 charge. In order to form a neutral compound, exactly one +ve and one -ve charges are required. Therefore, one sodium and one chlorine ratio is present in NaCl.
ANSWER: NaCl
