Nitrogen is lighter than bromine...

Nitrogen oxide particles travel faster than bromine particles because nitrogen oxides are smaller and lighter molecules, which allow them to move more quickly. Additionally, nitrogen oxides have lower molecular weight and higher temperature compared to bromine, which also contributes to their faster speed.
Sound can travel faster through space because space is a vacuum where there are no particles to slow down the transmission of sound waves. In a room at room temperature, sound travels through the molecules of the medium, such as air, which can slow down its speed.
Bromine (Br) has a molar mass of 79.904 amu (atomic mass units), which is extremely close to 80. Bromine is diatomic so when two bromine molecules are put together to create a diatomic gas, the molar masses of each bromine add to get a combined molar mass of 160 amu.
Water typically travels faster through gravel than sand soil because gravel has larger pore spaces that allow water to flow more easily. Sand soil has smaller pore spaces which can slow down the movement of water.
Lightning is faster than a shooting star. Lightning can travel at speeds of around 220,000 miles per hour (354,055 kilometers per hour), while shooting stars typically travel at speeds of around 36,000 miles per hour (57,935 kilometers per hour).
58 degrees because it is closer to 69 degrees.
