Answer:
2 moles
Explanation:
Given data:
Moles of water produced =?
Moles of propane = 0.5 mol
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of propane and C₃H₈.
C₃H₈ : H₂O
1 : 4
0.5 : 4/1×0.5 = 2 mol
Thus 2 mole of water are produced from 0.5 moles of propane.
Answer/explanation :
To calculate the number of mass, we use this formula
Number of mole = mass / molar mass
Since we are given the number of mole
Number of mole = 2.60mol
Mass = ?g
Molar mass of Li = 6.941g/mol
2.60mol = mass / 6.941 g/mol
Mass = 2.60 * 6.941
= 18.0466g
Therefore, the number of mass is 18.0466g
The minimum energy required to remove an electron from a potassium metal can be obtained by subtracting the energy of the incident photons from the kinetic energy of the removed photoelectrons. Based from the given values, the following equation is obtained:
Minimum energy required = 4.23×10^-19 J - <span>1.864×10^-21 J
</span>
We then get 4.2114 x 10^-19 J as the minimum energy required to remove the electron. We then convert this into units of energy per mole. This is to be done by using Avogadro's number which result to the following equation:
Minimum energy required per mole = 4.2114 x 10^-19 J x 6.022 x 10^23 mol^-1
The final answer is then 253.608 kJ/mol
Answer: Radiation
Explanation:
Any time you can feel heat without touching it, you are experiencing radiation.
