Last option that is none of above is right answer.
The questions tha science can answer are those can be tested to try to find a definite answer.
For example, whether light is wave or particle is matter of science.
Questions that cannot have a definite answer are the field of religion or philosophy, and are out of the boundaries of science.
For example, does a criminal deserve the punishment of not seeing light? It is a moral question, which to be responded needs the intervention of philosophy and that could have different anwers at different times and in different societies.
Answer: m = 11.2 g C7H16
Explanation: First convert the mass of CO2 to moles. Then do the mole ratio between CO2 and C7H16 which is 7:1. Finally convert the moles of C7H16 to the mass of C7H16.
Solution attached.
Answer:
robbery
Explanation:
The elements of robbery are 1) the felonious taking of personal property, 2) from the person or immediate presence of another, 3) against the will of the victim, and 4) accomplished by means of force or by putting the victim in fear.
Action of taking property by unlawfully from a person or place by force or threat of force is called robbery and all above condition satisfies the term robbery hence robbery is correct match.
Answer:
0.0559 mol
Explanation:
Step 1: Given and required data
- Volume of air (V): 1.35 L
- Pressure of air (P): 750 torr
- Ideal gas constant (R): 0.0821 atm.L/mol.K
Step 2: Convert "P" to atm
We will use the conversion factor 1 atm = 760 torr.
750 torr × 1 atm/760 torr = 0.987 atm
Step 3: Convert "T" to Kelvin
We will use the following expression.
K = °C + 273.15
K = 17.0 °C + 273.15 = 290.2 K
Step 4: Calculate the number of moles of air
If we assume air behaves as an ideal gas, we can calculate the moles (n) of air using the ideal gas equation.
P × V = n × R × T
n = P × V/R × T
n = 0.987 atm × 1.35 L/(0.0821 atm.L/mol.K) × 290.2 K = 0.0559 mol
