Answer:
See explanation
Explanation:
When the complex ion Co(H2O)6 2+(aq) is placed in solution and chloride ions are added, the following equilobrium is set up;
Co(H2O)62+(aq) + 4 Cl-(aq) <=> CoCl42-(aq) + 6 H2O(g)
Co(H2O)6 2+(aq) solution is pink in colour while CoCl42-(aq) solution is blue in colour.
Since the solubility of CoCl42-(aq) is endothermic, heating the solution will move the equilibrium position towards the right (more CoCl42-(aq) is formed and the solution is blue in colour).
When the solution is cooled, more Co(H2O)62+(aq) is formed and the equilibrium position shifts towards the left and the solution becomes pink in colour.
Answer:
the number of neutrons in an atom of the element is 10.
Explanation:
neutron: mass # -protons
neutron: 19 (18.9984 (rounded)) - 9
neutron: 19- 9 =10
whole number is equal to the number of protons.
Answer:
92,565,504,000 seconds in 31 days
Explanation:
multiply the days by 24 hours
31 * 24= 744
multiply the hours in 1440 minutes
1071360 minutes
now multiply that by 86400 seconds
92,565,504,000 seconds in 31 days
According to your equation, for every mole of iron oxide (Fe2O3), it takes 3 moles of carbon monoxide (CO). So for 1.75 moles, it takes 3 times as many moles of CO.
1.75 x 3 = 5.25 moles of CO.
I think your product is CO2. Dalton's Law sayeth that the coefficients tell us the ratios of moles. So if you hve 1.75 moles of Fe(III)oxide, 3*1.75 moles of CO are needed (in theory) to react completely. The answer is requested in moles, so you need go no further.
