Explanation:
Food wrappers and aluminium wrappers are widely use for packing various eatable items.
For example, in our homes our mother wraps our food for lunch in aluminium foil.
As it helps in keeping the food warm for hours.
Thus, we can conclude that out of the given options, a packaging waste is the garbage collector collecting.
False it is actually called a neutralization reaction.
For this problem, we use Graham's Effusion Law to find out the rate of effusion of chlorine gas. The formula is as follows:
R₁/R₂ = √(M₂/M₁)
Let 1 be N₂ while 2 be Cl₂
255/R₂ = √(28/70.8)
Solving for R₂,
R₂ = 405.5 s
<em>Thus, it would take 405.5 s to effuse chlorine gas.</em>
