Answer:
B
Explanation:
B is the best showing of a chemical reaction out of the choices
Your hypothesis is at the biggenning or the end of you summary
The molar mass (atomic weight ) of sodium is 23.0 grams/mole and the molar mass of sodium azide, NaN3 , is the mass of sodium, 23.0 gram/mole added to the molar mass of three atoms of nitrogen (14.0 x 3 = 42 gram/mole) which equals 65.0 grams/mole. The percentage of sodium is 23.0 /65.0 x 100 % = 35 %
Three of the intermolecular forces of attraction are roughly equal, the substances<span> will be </span>soluble in each other, <span>This means that </span>ionic<span> or </span>polar<span> solutes </span>dissolve<span> in </span><span>polar solvents</span>
The answer would be soluble. Think of it like salt. On it's own it is the white substance that you can see, but when you put it in water and stir it disappears. It is still there, but the physical appearance has changed. Also being explosive, flammable, and reactive are all chemical properties. Hope this helped!
