Answer:
Forensics.
Explanation:
That would be Forensics. Clues from a scene of a crime like clothing, blood and so on can be analysed in the science laboratory , helping to solve the crime.
Alchemy is not science, nor ethics nor politics.
Answer : The thermal energy produced during the complete combustion of one mole of cymene is -7193 kJ/mole
Explanation :
First we have to calculate the heat released by the combustion.
where,
q = heat released = ?
= specific heat of calorimeter = 
= change in temperature = 
Now put all the given values in the above formula, we get:
Thus, the heat released by the combustion = 70.43 kJ
Now we have to calculate the molar enthalpy combustion.
where,
= molar enthalpy combustion = ?
q = heat released = 70.43 kJ
n = number of moles cymene = 
Therefore, the thermal energy produced during the complete combustion of one mole of cymene is -7193 kJ/mole
Answer:
0.280 kg
Explanation:
m= n × MM
where
m is mass in grams
n is moles &
MM is molecular mass
The molecular mass of copper can be found on the periodic table and is 63.546.
We now have all the required information to perform the calculation
m= 4.41 × 63.546
m= 280.23786
m= 280 g
In order to convert this value to kilograms, divide by 1000
280/ 1000
= 0.280 kg
Answer:
i believe the answer is B.
Explanation :
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
