Answer:
The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 
Explanation:
Density is a characteristic property of a substance that relates to the amount of mass it has per unit volume. In other words, density is the property that matter, whether solid, liquid or gas, has to compress into a given space (it measures the amount of mass in a given volume of a substance). It is calculated as the quotient between the mass of a body and the volume it occupies:
In this case, you know:
Replacing:
Solving:
<u><em>The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 </em></u><u><em></em></u>
it is 6, all isotopes of carbon have 6 electrons and 6 protons which is why its atomic number is 6
Answer:
The answer to your question is below
Explanation:
Process
1.- Look for the longest chain
2.- Number the carbons of the main chain starting from the corner where the double bond is closer.
3.- Circle the branches
4.- Start naming the number where the branch is and the name of the branch.
5.- Name the main branch with the ending -ene.
5-methyl, 1-hexene or 5-methyl, hex-1-ene
See gthe structure below.
As you have not provided the options, still we can figure out the answer by understanding the key difference between saturated and unsaturated hydrocarbons.
SATURATED HYDROCARBONS are those hydrocarbons which only consist of a carbon carbon single bonds. All the bonds are sigma there are no pi bonds at all. Examples are shown below.
While, UNSATURATED HYDROCARBONS are those hydrocarbons which may contain either a double bond or triple bonds or both of them between the carbon atoms as shown below.
Yes the ANSWER is Correct-
On first half life the mass will be 10 gram
On second half life the mass will be 5 gram
On third half life the mass will be 2.5 gram
