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 :(
Answers
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.

What is the Substance that is oxidized in 2K+ S > K2S
Answers
Answer :]
This is an oxidation-reduction (redox) reaction:
S0 + 2 e- → S-II (reduction)
2 K0 - 2 e- → 2 KI (oxidation)
S is an oxidizing agent, K is a reducing agent.
Answer:
K
Explanation:
Here, in this reaction 2 moles of potassium react with 1 mole of sulfur to form 1 mole of potassium sulfide.
Let's compare the electronic configurations of both elements :
⇒ K = {2, 8, 8, 1}
⇒ K can attain noble gas configuration by losing one electron
⇒ K exists as : K⁺
⇒ S = {2, 8, 6}
⇒ S can attain noble gas configuration by the addition of 2 electrons
⇒ S exists as S²⁻
Now, we know that will lose protons when oxidized. Hence, here the substance which is oxidized is K

Answers
The balloon must be heated to a temperature of 150 °C in order to have a volume of 6.00 L.
How are volume and temperature of gases related?The volume of a gas is directly proportional to the temperature of the gas.
According to Charles' law: V1/T1 / = V2/T2
V1 =4.0 L
T1 = 9°C = (273. + 9) K = 282 K
V2 = 6.0 L
T2 = ?
T2 = V2×T1/V1
T2 = 6 × 282 / 4 = 423 K
423.2 K = 423 -273 = 150 °C

A chemical reaction can be reversed if?
The energy of the reactants exceeds the activation energy threshold.
The energy of the products exceeds the activation energy threshold.
The energy of the reactants is less than the activation energy threshold.
The energy of the products is less than the activation energy threshold.
Answers
Answer: The energy of the products exceeds the activation energy threshold.
Explanation:
In the reverse reaction, the reactants of the forward reaction are now the products of the reverse reaction and vice versa.
This means that normally since you would need the energy of the reactants of the forward reaction to exceed the activation energy threshold, in the reverse reaction, the energy of the products would need to exceed the activation energy threshold.
1. When conducting this experiment, some procedures call for heating the substance several times and recording the mass after each heating, continuing until the mass values are constant. Explain the purpose of this process and how it might reduce errors.
Answers
The purpose of this process is to reduce the risk of having outliers of false results.
What is a good scientific experiment?It is important to bear in mind that a good scientific experiment usually tests one independent variable at a time, and that is why it is important to keep all other potential variables constant and to use a control group.
Although, the experiment you are referring to in your question is missing the general principle when conducting an experiment is the running of multiple tests before coming up with an actual test result.
Therefore, when completing a science experiment it is important to run multiple tests like heating the substance several times until a constant mass value is obtained, in other to ascertain the results. the reason why such process is undertaken is to reduce the risk of having outliers of false results.
A scientific experiment involves several procedures and this depends on the type and purpose of the experiment.
for example ;
An experiment with the purpose of determining how the mass of an object reacts to heat will require the mass of the object to be recorded after heating the object/substance several times.
Hence we can conclude that the purpose of the process is to reduce the risk of having outliers of false results.

Answers
The specific heat of the metal is calculated using the change in temperature, heat, and mass. The specific heat of the metal is 0.21 J/g °C.
What is heat energy?Heat energy is a transfer of the energy lost by a system to the energy gained by another system. The calorimeter is used to measure the specific heat of the system.
Given,
Mass of metal = 500 gm
Temperature = 100 °C
Mass of water = 250 gm
Temperature = 40 °C
Specific heat of water = 4.184 J/g °C
The specific heat (c) of metal is calculated as:
Q = mC ΔT
and, Q (metal) = Q (water)
Substituting values in the above equation:
(500 )(c)(100) = (250)(4.184)(50-40)
50000 c = 10460
c = 0.21 J/g °C
Therefore, the specific heat of metal is 0.21 J/g °C.
