even no = 3/6 = 1/2
no. less than 5 = 4/6 = 2/3
Methane, CH4, would have the lowest boiling point among the three since it has the lowest number of carbon and has no functional groups. Methanol would have the highest boiling point since it has a functional group which contains hydrogen bonding which much stronger than the one in CH3Cl. Hope this helps.<span />
Answer:
Explanation:
A chemical property describes the ability of a substance to undergo a specific chemical change.
A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.
Differences
Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change.
Physical properties are properties that can be observed without bringing a chemical change.
Another one
chemical properties; can be used to predict how substances react.
chemical changes; It is mostly used in identifying or describing the substance.
Answer:
0.385J/g°C
Explanation:
Using the following formula;
Q = m. c. ∆T
Where;
Q = amount of heat (joules)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
According to the provided information in this question;
Q = 318 cal
1 calorie = 4.184J
318 cal = 318 × 4.184 = 1330.512J
m = 279g
∆T = 27.2°C - 14.8°C = 12.4°C
Hence, using Q = m. c. ∆T
c = Q ÷ (m. ∆T)
c = 1330.512 ÷ (279 × 12.4)
c = 1330.512 ÷ 3459.6
c = 0.385
Therefore, the specific heat of copper is 0.385J/g°C
The charges in the finger are attracted by the charges in the doorknob because charges that are the same repel each other. Charges that are different attract each other. The electric field is pulled toward the other charged object if their charges are different.
