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
Answer:
Approximately 206 grams.
Explanation:
How many moles of sulfuric acid 
are there in this solution?
.
The unit for concentration "
" is equivalent to mole per liter. In other words, 
. For this solution, the concentration of is 
.
.
What's the mass of that 
of ?
Start by finding the molar mass 
of .
Relative atomic mass data from a modern periodic table:
- H: 1.008;
- S: 32.06;
- O: 15.999.
.
.
.
In other words, the chemist shall need approximately 206 grams of to make this solution. As a side note, keep in mind that the 206 grams of also take up considerable amount of space. Therefore it will take less than 5.00 L of water to make the 5.00 L solution.
Answer: A sodium atom has one electron in its outer shell. The atom is more stable if it has a full outer shell. A sodium atom can lose its outer electron. It will still have 11 positive protons but only 10 negative electrons.
Explanation:
Answer: Nickel has one more proton.
Explanation:
The Periodic table orders elements based on their atomic number not by their atomic mass even though this order usually coincides with the atomic masses of the elements. Occasionally however, this is not the case as is proven by Cobalt and Nickel.
The atomic number of an element refers to the number of protons that the element has in its nucleus. Cobalt has 27 protons whilst Nickel has one more proton at 28 which is why it comes after Cobalt.
