Which of the following will be the result of dissolving a substance?
nata0808 [166]

Answer:

The answer to your question is d.

Explanation:

Chemical changes happen when the substance changes its original properties to form a new one. So option 1 is incorrect.

Dissolving a new substance does not form new substances as I mentioned before. The second option is incorrect.

The third option is also wrong because dissolving a substance does not separate anything.

The fourth option is correct, dissolving a substance allows us to make solutions.

Spell out the full name of the compound.
scoundrel [369]

Answer:

2–methylpropene.

Explanation:

To successfully name the compound given in the question, we must observe the following:

1. Determine the functional group of the compound.

2. Locate the longest continuous carbon chain. This gives the parent name of the compound.

3. Identify the substituent group attached and locate it's position by giving it the lowest possible count.

4. Combine the above to obtain the name of the compound.

Now, let us determine the name of the compound. This is illustrated below:

1. The functional group of the compound is the double bond i.e the compound is an alkene.

2. The longest continuous carbon chain is 3 i.e propene since it is an alkene.

3. The substituent group attached is methyl i.e CH3. In this case, we'll start counting from the side of the double bond being the functional group. Therefore, the methyl group i.e CH3 is at carbon 2.

4. Therefore, the name of the compound is:

2–methylpropene

Which is a product in the following chemical reaction? CH4 + 2O2 → CO2 + 2H2O
NeTakaya

The correct answer is H20.

In a chemical reaction, there are always two sides, the reactant side and the product side. The reactants are the elements that are reacting together. They are always written at the left side of a chemical equation, with a plus sign written in between two elements. The products are the new compounds that are formed from the reaction of reactants. They are always written at the right side of a chemical equation and a plus sign is used to join them if they are more than one. An arrow pointing to the products usually connect the two side of the equation. For the question give above, the reactant are CH4 and O2 and the products are CO2 and H2O.
