One mole of Fe(NO3)3, or iron(III) nitrate, has three moles of nitrate molecules, which have three moles of oxygen atoms each. We can show this mathematically:
1 mole Fe(NO3)3 * (3 moles NO3)/(1 mole Fe(NO3)3) = 3 moles NO3
3 moles NO3 * (3 moles Oxygen)/(1 mole NO3) = 9 moles Oxygen
9 moles of Oxygen in one mole Fe(NO3)3
Answer:
Check if the ions of two compounds exchange places.
Explanation:
The definition of single replacement is a reaction when an ion replaces another ion, thus the name.
Answer : It is a conclusion.
Explanation:
Conclusion: It is a judgement or decision which can be attained by reasoning.
From the observation table given we can conclude that :
- Aluminum ,bronze and steel took 27,45 and 80 seconds to melt small piece of wax respectively which means that more time will be required by them to transfer heat to the food while cooking. Hence, food will take more time to cook in them.
- Copper took less time of 15 seconds to melt the small piece of wax in comparison to other metal pots which means that it is a good conductor of heat in comparison to other. Hence, copper pot would be better for cooking food quickly.
After analyzing the observations and results in an experiment conclusion was made that copper pots are best for cooking foods.
