Explanation:
Filtration can be used to separate an insoluble solid from a liquid, or a precipitate from the reaction mixture in which it formed. The solid which collects in the filter paper is called the residue. The clear liquid which passes through the filter paper is called the filtrate.
Answer:
Explanation:
We can start with the <u>reaction of hydrogen and nitrogen to produce ammonia</u>, so:
When we <u>balance</u> the reaction we will obtain:
Now, the <u>production of nitric acid</u> with oxygen would be:
If we <u>balance</u> the reaction we will obtain:
Now, if we put the reactions together we will obtain:
We can <u>multiply</u> the second reaction by "2":
We have "" on <u>both sides</u>. In the first reaction is in the right in the second reaction is on the left. Therefore we can <u>cancel out</u> this compound and we will obtain:
On this reaction, we will have 2 nitrogen atoms on both sides, 6 hydrogen atoms on both sides, and 8 oxygen atoms on both sides. So, this would be the <u>net reaction</u> for the production of nitric acid.
Answer is:
1: Kr.
2: Cl₂.
3: F₂.
4: O₂.
5: N₂.
6: He.
The lighter (smaller) particles move more quickly than heavier (larger) ones at the same temperature.
Calculate molar masses of the compounds:
M(Cl₂) = 70.9 g/mol; molar mass of chlorine gas.
M(F₂) = 38 g/mol, molar mass of fluorine gas.
M(He) = 4.002 g/mol; molar mass of helium.
M(Kr) = 83.8 g/mol; molar mass of krypton.
M(N₂) = 28.01 g/mol; molar mass of nitrogen gas.
M(O₂) = 32 g/mol; molar mass of oxygen gas.
Once you add detergent (base) to water (H2O), you are breaking the surface tension.
