Unfortunately, they're not multiple choice, so I have no possible answers to list, I believe 1. might be "2-methylhexane" but I'm unsure how to write the double bond that's shown in the structure, thanks! :)
Edit; the screenshots posted out of order, my apologies :(
Answer:
1.) There are 6 carbons in the longest possible parent chain (hex-). Since there is a double bond, this is an alkene. The lowest possible carbon the double bond consists of is the 2nd carbon. There is also a methyl group on the 2nd carbon. All together, this makes the structure: 2-methyl-2-hexene.
2.) There are 9 carbons in the longest possible parent chain (non-). The lowest possible carbons the methyl groups are on are the 3rd and 5th carbons. The lowest possible carbon the ethyl group is located on is the 4th carbon. Remember, branches are listed alphabetically. All together, this makes the structure: 4-ethyl-3,5-dimethylnonane.
3.) There are 7 carbons in the longest possible parent chain (hept-). There is a triple bond, making this an alkyne. The lowest possible carbon the triple bond consists of is the 2nd carbon. The lowest possible carbon the methyl group is on is the 4th carbon. All together, this makes the structure: 4-methyl-2-heptyne.
4.) There are 10 carbons in the longest possible parent chain (dec-). The lowest possible carbon the propyl group is on is the 5th carbon. All together, this structure is: 5-propyldecane.
5.) There are 4 carbons in the longest possible parent chain (but-). The lowest possible carbon the methyl group is on is the 2nd carbon. All together, this makes the structure: 2-methylbutane.
6.) There are 5 carbons in the longest possible parent chain (pent-). There is a double bond, making the molecule an alkene. The lowest possible carbon the double bond consists of is the 2nd carbon. The lowest possible carbon the methyl group is on is the 2nd carbon. All together, this makes the structure: 2-methyl-2-pentene.

Use Charles's Law to interpret the following problem and then select the correct answer below.
A 250mL compressed tank is filled with Hydrogen gas and has a pressure of 100kPa. If all of the Hydrogen gas is removed from the tank and pumped into a 1L tank what happens to the temperature of the gas?
Question 2 options:
The temperature in the 1 L tank increases.
The temperature in the 250 mL tank decreases.
All of the above.
None of the above.
The temperature in the 250 mL tank increases.
Considering the Charles's Law, the temperature in the 1 L tank increases.
What is the Charles's LawCharles' Law consists of the relationship that exists between the volume and the temperature of a certain amount of ideal gas, which is maintained at a constant pressure.
This law determines that for a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature. That is, the volume is directly proportional to the temperature of the gas.
Mathematically, Charles' law is a law that says that when the amount of gas and pressure remain constant, the ratio between volume and temperature will always have the same value:
[tex]\frac{V}{T} =k[/tex]
Analyzing an initial state 1 and a final state 2, the following is true:
[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]
Temperature of the gas in this caseAccording to Charles' law, the volume is directly proportional to the temperature of the gas. So if the volume increases from 250 mL to 1 L, the temperature will also increase.
This is, the temperature in the 1 L tank increases.

Answer:
4.041 moles C₂H₆
Explanation:
To convert from grams to moles, you first need to determine the molar mass of C₂H₆. The molar mass is the combination of the atomic masses times the quantity of each element present in the molecule. The atomic masses usually be found on the periodic table. They represent how much the element weighs per one mole.
Carbon (C) Atomic Mass: 12.01 g/mol
Hydrogen (H) Atomic Mass: 1.008 g/mol
Molar Mass (C₂H₆): 2(12.01 g/mol) + 6(1.008 g/mol)
Molar Mass (C₂H₆): 30.068 g/mol
Now that you have the molar mass, you can multiply this ratio to the given value. Keep in mind that in order to go from grams to moles, the numerical value should be place in the denominator of the molar mass ratio. This allows for the cancellation of the unit 'grams'. The final answer should have 4 significant figures because the given value also has 4 sig figs.

What is the molarity of 985 mL solution with 0.81 moles KF?
M
Please help I need it done tonight
Answer:
0.82 M
Explanation:
You have been given moles and volume (in mL). To find the molarity of the solution, you need to (1) convert mL to L and then (2) plug moles and volume into the molarity formula.
985 mL / 1,000 = 0.985 L
Molarity (M) = moles / volume (L)
Molarity = 0.81 moles / 0.985 L
Molarity = 0.82 M
A certain chemical reaction telesales 24.7 kk/g of heat for each gram of reactant consumed
The mass of reactant that would produce 800 Joules of heat is equal to 800 J × (1 kJ/1000 J)/(24.7 kJ/g).
How to calculate the mass of reactant?In order to determine the mass of reactant that would produce 800 Joules of heat, we would set up a conversion equation as follows:
Note: 1 kJ is equal to 1000 Joules.
Conversion:
1 gram = 24.7 kJ
X gram = 800 Joules
Therefore, the mass of reactant that would produce 800 Joules of heat is given by:
Mass = Heat × (conversion factor/rate of heat)
Mass = 800 J × (1 kJ/1000 J)/(24.7 kJ/g).
