Answer:
4.82 g
Explanation:
To solve this problem we'll use the <em>definition of molarity</em>:
- Molarity = moles / liters
We are given the volume and concentration (keep in mind that 100mL=0.100L):
- 0.825 M = moles / 0.100 L
Now we <u>calculate the number of NaCl moles required</u>:
Then we convert 0.0825 NaCl moles into grams, using its molar mass:
- 0.0825 mol * 58.44 g/mol = 4.82 g

low electronegativities.
malleable – able to be pounded into sheets.
Explanation:
They didnt have a powerfull enough microscope to see them an when they could they were moving to fast unless they were cold
Answer:
This has some interesting History in it.
Peat moss was once pounded into a sort of brick; sometimes with a little coal, these bricks were put to dry, and used for fuel.
The “Historical” part is in the name. I won’t go into why, ‘cause I type so slow and it is “extra”, but the peat, or coal, being TRULY organic, (that is made from plants) and burned as fuel is called “carbonixation”.
Explanation: Sort of a “Carbon + Oxidation”; many things in Chemistry have strange names that seem at first to make no sense; like “essence of Hartshorn”, is Ammonia (or ammonium hydroxide). A Hart is/was a type of deer in England and that area, and amines in the horn, when distilled, would yield Ammonia, “The Essence of Hartshorn”. Even the term “aromatic” has a long History, as do many compounds and nomenclature.
I hope that will do it.
Answer:
A team of Chinese researchers have turned cheap copper into a new material “almost identical” to gold, according to a study published in peer-reviewed journal Science Advances on Saturday. The fast-moving ionized particles blasted copper atoms off the target.
hope this helps
have a good day :)
