Answer:
Kc of the reaction is 0.9375
Explanation:
Step 1: Data given
Moles of SO2 = 0.40 moles
Moles of O2 = 0.60 moles
Volume = 1.00 L
After the reactio we find 0.30 moles SO3
Step 2: The balanced equation
2 SO2(g) + O2(g) ⇔ 2SO3(g)
Step 3: Calculate Kc
Kc = [SO3]² / ([SO2]²[O2])
Kc = 0.30² / (0.40²*0.60)
Kc = 0.9375
Kc of the reaction is 0.9375
<u>Answer:</u> The molarity of ions in the solution is 0.306 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Mass of solute = 15.6 g
Molar mass of = 295.6 g/mol
Volume of solution = 345 mL
Putting values in above equation, we get:
As, 1 mole of produces 1 mole of copper (II) ions and 2 moles of nitrate ions.
So, molarity of ions = (2 × 0.153) = 0.306 M
Hence, the molarity of ions in the solution is 0.306 M
I think the answer most be d
Answer: 565.245kJ
To answer this question, you need to know how much water heat capacity which was 4.187 kJ/kg K. First, we need to find the calorie absorbed by water. Since the sample is 1kg, the initial temperature is 21 ∘C and final temperature is 34.5 <span>∘C then the calculation would be:
Energy= (Final temp - initial temp) * heat capacity * mass
Energy = (34.5-21) </span>∘C * 4.187 * kJ/kg K * 1kg= 56.5245 kJ
The energy is made from 0.1 gram, then for 1 gram of energy it should be:
1 gram/ 0.1gram x 56.5245 kJ= 565.245kJ
Answer:
Ok; first of all, you must correct the Molecular Formula; FeSO4•7H20
So, work out the Molar Mass;,
(4x18)O+ 55.? Iron + 32 Sulphur, PLUS
(7x 18) H2O = 1 molar mass.
Now, take that times 5.24, show your work & check the Mol. Weights, I am going by memory.
