Help a Lost Student: Calculating Heat Transfer in H2O

AI Thread Summary
To solve the homework assignment regarding the temperature change of water when a heated iron bar is placed in it, the principle of conservation of energy is applied, where the heat lost by the iron bar equals the heat gained by the water. The specific heat capacities of both materials are crucial for the calculations. The formula Q = mcΔT is used, where Q is the heat energy, m is mass, c is specific heat capacity, and ΔT is the change in temperature. The specific heat capacity of iron is significantly lower than that of water, which will influence the temperature change. By calculating the heat lost by the iron bar and setting it equal to the heat gained by the water, the final temperature of the water can be determined. This approach ensures that no heat is lost to the surroundings, simplifying the calculations.

I am lost on this homework assignment, and I am really hoping that you guys can help me out. Here goes:
A 500.0-g Fe bar at 212 degrees C is placed in 2.0L of H20 at 24.0 degrees C. What will be the change in temperature of the H2O? (if is assumed that no heat is lost to the surroundings)

I would really appreciate any help you can provide.

The heat lost by the iron bar is the same as the heat gained by the water.

Do you know how to find the temperature change of a material when it loses or gains a given amount of heat?

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
