The full question is shown in the image attached
Answer:
See explanation
Explanation:
In naming an alkane, the first thing we do is to obtain the parent chain by counting the number of carbon atoms in the chain.
When we obtain that, then we identify the substituents and number them in such a way that they have the lowest numbers. The compounds shown have the following names according to the order in which the structures appear in the image attached;
1. 2-methyl propane
2. 2,4-dimethyl heptane
3. 2,2,3,3-tetramethyl butane
4. 5-ethyl-2,4-dimethyl octane
Answer:
The answer is in the explanation.
Explanation:
The KHP is an acid used as standard in titrations to find concentration of bases as NaOH.
The reaction that explain this use is:
KHP + NaOH → KNaP + H2O
<em>where 1 mole of KHP reacts per mole of NaOH</em>
That means, at equivalence point of a titration in which titrant is NaOH, the moles of KHP = Moles of NaOH added
With the moles of KHP = Moles of NaOH and the volume used by titrant we can find the molar concentration of NaOH.
The moles of KHP are obtained from the volume and the concentration as follows:
Volume(L)*Concentration (Molarity,M) = moles of KHP
If the concentration is more or less than 0.100M, the moles will be higher or lower. For that reason, we need to know the concentration of KHP but is not necessary to be 0.100M.
Answer:
- smoke
- marshmallow
- paint
- Body spray
Explaination:
Firstly, what are colloids?
Colloids are a mixture of two substances:
- one of those substances are insoluble and inseparable
There are 4 types of colloids:
- Sol- Solid in a liquid
- Emulsion- Liquid in a liquid
- Foam- Gas in solid/liquid
- Aerosol- Solid/liquid in gas
So on to the answers:
- Smoke consists of solid and gas and since the solid is being carried by the gas, it is a solid in a gas (aerosol)
- Marshmellow consists of tiny air bubbles and sugar(solid), the air bubbles is inside the solid making it a gas in a solid (foam)
- Body spray turns gas into liquid after spraying it through the can, making it a liquid in a gas (aerosol)
- Paint dries up to become solid which makes it a solid is a liquid (sol)
Hope y'all understand
When gas molecules condenses, they lose energy.
