5. Why is it necessary to regularly test the pH of pool
water?
Answer:
To ensure that everyone enjoys using your pool, it is important to keep the swimming pool pH levels in balance at all times. If the pH is too high, it could cause skin irritation and corrode metal parts on the pool. If the pH is too low, it could create a situation where the chlorine in the pool isn't as effective.
Explanation:
Answer:
I don't see multiple choice, so I'll answer this based on what I have learned on my free time.
Explanation:
Usually, when a ton of Urine is in a pool, it can throw off the Ph balance, and can even damage human eyes. Trust me, it's happened to me one time. my eyes burned like fire.

Give an example of a chemical reaction during which a single substance breaks
down. *
Answer:
2NaCl(l) => 2Na(s) + Cl₂(g)
Explanation:
Electrolysis of melt NaCl to form sodium (Na) metal and chlorine (Cl₂) gas.
This is a class of reaction called 'Decomposition Rxns'. For what it's worth, there are 6 distinct compound types that undergo breakdown by decomposition. The acronym C O A C H E can help remember them.
C - Carbonates => CaCO₃(s) => CaO + CO₂
O - Oxides of Metals => 2Fe₂O₃(s) => 4Fe°(s) + 3O₂(g)
A - Acids (Oxoacids) => H₂CO₃(aq) => CO₂(g) + H₂O(l)
C - Chlorates, Bromates & Iodates => 2KClO₃(s) => 2KCl(s) + 3O₂(g)
H - Hydroxides => Ca(OH)₂(s) => CaO(s) + H₂O(l)
E - Electrolysis => see above electrolysis of NaCl(l)
Answer:
2NaCl(l) => 2Na(s) + Cl₂(g)

Explanation:
Many human activities result in carbon dioxide emissions.
Our carbon footprint is a measure of how much carbon dioxide we each cause to be produced.
(a) Why should we be concerned about our carbon footprint?
(b) Most power stations in the UK burn coal.
Coal was formed from tree-like plants over millions of years.
Suggest why burning wood instead of coal would help to reduce our carbon footprint.
Answer:
: the average human-driven CO2 emissions per year climbed 1.4%
every household makes about 7 tons worth of Co2
A C02 footprints are produced at such high rates and hurts plants and the environment
B coal is a very inexpensive and efficient way to generate electricity. Since its a large quantity of them which still produces alot co2 unlike wood, burning wood doesn't produce as much but it's much harder to ignite and get to last because it takes coal almost 100 degrees and wood takes about 700 degrees

20 milliliters of water are poured into a graduated cylinder. A sample of metal is added. The water rises to the 32-milliliter line. What is the volume of the piece of metal?
Answer:
12
Explanation:
32-20= 12
This is because when the metal is added it adds to the volume of the liquid hence to find the metal itself subtract the final volume from Intel volume
[tex]\tt \underline{Answer:}[/tex]
12
[tex]\tt \underline{Explanation:}[/tex]
The water increases/rises to the 32 milliliter line, and before it was 20 milliliters of water in a graduated cylinder. So...to identify/find the volume, you can basically subtract.
32 - 20 = 12.

How are clouds formed? Simple answer please!
Answer:
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.
