Cl2 + NaI -> NaCl + I2
We are unbalanced with Chlorine and Iodine so we can do this:
Cl2 + 2NaI -> 2NaCl + I2
Reactants: Cl = 2, Na = 2, I = 2
Products: Cl = 2, Na = 2, I = 2
So we are balanced.
Answer:
A continuous spectrum contains many different colors, or wavelengths, with no gaps. Perfectly white light shined through a prism causes dispersion of the light, and we see a rainbow. Conversely, when a gas is heated, the atoms in the gas absorb the energy and emit light, and an emission spectrum results.
Explanation:
In my opinion yes, as of now, almost anyone could get there hands on lets say an explosive. Have you heard of dynamite fishing? It is illegal, but it is still done once people have access to dynamite, then what ends up happening not only do marine wildlife get killed but it pollutes the water and lessens the chance of the natural cycle of life. Also there are several other factors, firstly, what will you do with an explosive once you get your hands on it? Perhaps you could just use an explosive for fun/personal entertainment...that isn't right and it could harm people. So, to conclude the harder it is for people to access explosives or even acclerants the better...and to add this can be possible by making people get like some sort of licence to use them, and let them be trained in certain conditions so that there is no regrets once they have access to them. I know my idea sounds far fetched but its a thought!
