It is easiest to tell if a solution is saturated if there is residue on the bottom. If it crystallized, the solution is saturated. If it is a supersaturated solution, there will not be crystallization unless more of the solute is added, at which point all of it will crystallize.
The costs, risks, and benefits to building a nuclear waste storage facility somewhere else
Answer:
Most substances on earth are compounds and most interesting chemistry is done with compounds. Most interesting chemistry is done with mixtures of compounds although they often start with pure compounds and then do reactions as mixtures. Most chemistry is carried out in liquid solutions made up of compounds that are solids, liquids, or gases in their pure form.
Explanation:
Answer:
The depth of the lake is 67.164 meters.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas in bubble= ?
= final pressure of gas = 0.980 atm
= initial volume of gas =
= final volume of gas = 8.00 × V
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
pressure of the gas in bubble initially is equal to the sum of final pressure and pressure exerted by water at depth h.
Where :
density of water =
g = acceleration due gravity =
h = 67.164 m
The depth of the lake is 67.164 meters.
Answer:
6 neutrons
Explanation:
The mass of on atom is the number of protons plus neutrons. This element is bromine as its' mass number is 5. If its' mass number is 5 that means that there are 5 protons in the nucleas. 11 (atomic number) - 5 (# protons) = the number of nuetrons.
