The answer is <span>C. Glucose is an organic molecule.
Glucose is carbohydrate so it cannot be a protein or a nucleic acid. It is an organic molecule. The organic molecule is compound consisting of carbon to which are attached hydrogen, oxygen, and nitrogen. Since, g</span><span>lucose is a simple sugar made up of carbon, hydrogen, and oxygen, it, as well as any other carbohydrate, is the organic molecule.</span>
Answer:
5 moles of Argon is present in the mixture.
Explanation:
Total pressure of the gaseous mixture = 4 atm
Total number of moles = 16
Partial pressure of Ne = 2.75 atm
By Dalton's law of partial pressure, the total pressure of gaseous mixture is the sum of partial pressures of individual gases which are non-reactive.
Hence:
Also :
Partial pressure = mole fraction*total pressure
∴Number of moles of Argon = 5
Answer:
c = 1.61 j/g.°C
Explanation:
Given data:
Mass of oil = 9 g
Heat added = 824 j
Initial temperature = 30°C
Final temperature = 87°C
Specific heat of oil = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
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 = Final temperature - final temperature
ΔT = 87°C - 30°C
ΔT = 57 °C
Q = m.c. ΔT
824 j = 9 g × c × 57 °C
824 j = 513 g. °C × c
c = 1.61 j/g.°C
