Answer: The possible structure for this compound is 2,4-dimethyl-3-pentanone
Explanation:
It should be noted that, If the 1H NMR spectrum of a compound with formula C7H14O gives a doublet at 9.2 ppm. The possible structure for this compound is 2,4-dimethyl-3-pentanone
Answer:
2621.75 j heat is required to increase the temperature 25.5°C to 46°C.
Explanation:
Given data:
Mass of sample = 142.1 g
Initial temperature = 25.5°C
Final temperature = 46°C
Specific heat capacity of Al = 0.90 J/g.°C
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 46°C - 25.5°C
ΔT = 20.5°C
Q = 142.1 × 0.90 J/g.°C × 20.5°C
Q = 2621.75 j
Thus, 2621.75 j heat is required to increase the temperature 25.5°C to 46°C.
False because how is a metal gonna turn into a different kind
Answer:
A solution of CH3Cl will not conduct electricity
Explanation:
Ionic substances conduct electricity because the solution is composed of ions. Ions are charge carriers in a solution. When an ionic substance is dissolved in water, the substance dissociates into its component ions. The concentration and activity of these ions determines the conductivity of the solution.
However, molecular substances are not composed of ions. Since they are not composed of ions, they do not dissolve in water to yield ions. This implies that solutions of molecular substances are do not conduct electricity.
CH3Cl is a molecular substance. It is not composed of ions, hence its solution does not conduct electricity.
