The average rate of reaction over a given interval can be calculated by taking the difference of concentration on a particular given reactant, and dividing it by the total time. In this case, (1.00 M - 0.655 M)/30 s = 0.0115 M/s, or 0.0115 mol/L-s, and this is the final rate of reaction.
Answer:
A I did the exam and I saw A sorry if it is wrong dont have the best of memory
The concentration of in the stack gas = 12 ppmv
That means 12 L of is present per
The given temperature is 273 K (0 C) and pressure is 1 atm. At these conditions, 1 mol of gas would occupy,
V = 22.4 L
1 mol occupies 22.4 L
Moles of =
Mass of = =μg
Converting :
=
Calculating the concentration in μg/:
Answer:
The amount of oxygen in 2.5 moles of water is 40 grams. The molecular formula of water is H₂O. 1 mole of water contains 1 mole of oxygen
There can be two electrons in one orbital maximum. The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.
