Answer:
A.) trans-2,3-dichloro-5-methyl-2-hexene
Explanation:
The proposed question and structure has been attached to this answer.
The<em> cis</em>- and <em>trans</em>- isomers are used to denote the alignment of the functional groups to the carbon chain side. From the diagram, we see that:
- the two chloro groups on the main compound are in opposite directions (-<em>trans</em>), and not the same sides (-<em>cis</em>)
- The bottom extended methyl group is on the 5th carbon as we count from left to right
- there's a total of 6 carbon atoms with 1 double bond on the second to third carbon.
Hence the name <u>trans-2,3-dichloro-5-methyl-2-hexene</u>
Answer:
4.9cm or 4.90cm
Explanation:
Use column method and align the numbers. Make sure you add the decimal point before you write the answer, otherwise the value would be wrong.
Answer:
1.38 atm
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant
P1V1= P2V2
P1 = 2.2 atm, V1 = 2.5L ,
P2 = ? , V2 = 4L
2.2 × 2.5 = P2 × 4
Divide both sides by 4
P2 = 5.5 ÷ 4
P2 = 1.38 atm

Answer:
The inner diameter of the steam tube is 0.1185 m.
Explanation:
m = mass flow rate
= density of the liquid
V=specific volume =
v = velocity of the liquid
A = area of cross-section
Diameter of the cross-section = d = 2r
Given: m = 18 kg/s, v = 60 m/s,A=?, 
Area of the inner cross section = 
d = 0.1185 m
The inner diameter of the steam tube is 0.1185 m.
