Answer:
See the answer below, please.
Explanation:
Organic compounds are those produced by living beings (molecules associated with living beings) and correspond to carbon compounds (the main difference with inorganic compounds). The latter are produced by natural processes or in the laboratory.
Example of organic products: alkanes (methane), alcohols (ethanol or ethyl alcohol)
Example of inorganic products: sodium hydroxide, sodium chloride
M=D*V
D=m/V
m=119 g
V= 20 cm³
D=119 g/20 cm³
D= 5.95 g/cm³
Answer:
V = 16.81 L
Explanation:
Given data:
Number of moles = 0.75 mol
Temperature = standard = 273 K
Pressure = 1 atm
Volume of balloon = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will rearrange the formula.
V = nRT/P
V = 0.75 mol ×0.0821 atm.L/mol.K ×273 K / 1 atm
V = 16.81 atm.L/ 1 atm
V = 16.81 L
Answer:
355Joules
Explanation:
The amount of heat absorbed can be calculated using the formula:
Q = m × c × ∆T
Where;
Q = amount of heat absorbed in joules
m = mass of substance in grams
c = specific heat capacity of solid (0.727 J/g°C)
∆T = final temperature - initial temperature (°C)
According to the information provided in this question;
Q = ?
m = 12.3g
∆T = 62.1°C - 22.4°C = 39.7°C
c = 0.727 J/g°C
Using Q = m × c × ∆T
Q = 12.3 × 0.727 × 39.7
Q = 355.001
Q = 355Joules
Hence, 355J of heat was absorbed
