Answer:
280 mL
Explanation:
Ideal gas law:
PV = nRT
Rearranging:
V / T = nR / P
At constant pressure:
V₁ / T₁ = V₂ / T₂
Substituting values:
250 / (15 + 273) = V / (45 + 273)
V = 276
Rounded to two significant figures, the volume will be 280 mL.
When using the ideal gas law, remember to always use absolute units for temperature, like Kelvin.
The process which has taken place is called CRYSTALLIZATION.
Generally, crystallization is the process by which solid crystals are precipitated from solution. Crystallization can also occur when a crystal melt or when a crystal get deposited directly from a gas, although these cases are rarer compare to crystals forming from solutions.

Explanation:
In electrolysis, a solution called the electrolyte is decomposed by the passage of direct current through it.
The points through which current enters and leaves the electrolyte are called electrodes. In electrolysis, oxidation occurs at the anode and reduction occurs at the cathode.
In the electrolysis of water; at the anode oxygen is produced as follows;
4OH^-(aq) -----> 2H2O(l) + O2(g) + 4e
It's your hw so you really should understand it so you dont have to ask for help so I'll try to explain it the best I can.
1.SD (only one switch occurs, between fluorine and bromide)
2.DD (two things are switched, sulfate and nitrate)
3. D (One compound is broken up into smaller compounds)
4.C (The products of combustion are always h20 and co2)
5.DD (again, two things are switched, bromide and nitrate)
6.SD (In SDR, look for a lone molecule reacting with a compound)
7.S (two smaller compounds become one big compound)
8. D( A big compound is broken up)
9. DD (I think Its DD because two molecules were displaced)*not sure
10.DD(two molecules are displaced, phosphate and hydroxide)
