CHEMISTRY HELP PLEASE!
WINSTONCH [101]
1) is called 3-methyl hexane because we choose the longest possible continuous chain which has 6 carbons and start numbering from the side that gives the branch lowest possible number.

2) is called 2-methyl-2-butene because we have to give the double bond lowest possible number but in this case double bond in position 2 from both sides so we start from the side gives the branch number 2 not 3

3)  is called 7-Ethyl-4-decyne because we have to start from the side that gives the triple bond lowest possible number which is 4 and the branch will be at position 7 (note that the name of 10 carbon is incorrectly written in the choices is called decane (as alkane) or decyne when contains triple bond)

4) is called 2,3-Dimethyl pentane because it is 5 carbons (pentane) and we have two branches of the same alkyl (dimethyl) in positions 2 and 3

5) is called 1-Butanol because it contains 4 carbons and has one OH as functional group which take the suffix -ol in position 1 so we said the name as 1-butanol (remember to give the functional group lowest possible number)

6) is called propyl butyl ether because the longest chain is 4 carbons which called butyl and the smallest chain is propyl, it also has another name 1-Propoxy butane <span />

What is the total amount of heat absorbed by 100.0
sergejj [24]

Answer:

Option (B) 6270J

Explanation:

The following were obtained from the question:

M = 100g

T1 = 30°C

T2 = 45°C

ΔT = 45 —30 = 15°C

C = 4.18J/g°C

Q=?

Q = MCΔT

Q = 100 x 4.18 x 15

Q = 6270J

Therefore, the total amount of heat absorbed is 6270J

Airida [17]
Answer : ZnCO_{3} will be 1 mole of ZnCO_{3} / 125. 40 g of ZnCO_{3}

Explanation : The molar mass and the formula units are the same thing in any compound so when given a molar mass of compound then one mole of that compound is divided by its molar mass. Where one mole will be equal to avogadro's number which is 6.022 X 10^{23}.
