During a heating process, 400 J of heat was absorbed by a 210 g block of iron (c iron = 0.449 J/g·°C). If the block started at room temperature (298 K), what will the final temperature be?

High-energy and unstable.

The answer is neonhope it

The answer to the question: choose the correct statement.  a) when ethane reacts with fluorine gas the product is less stable.b) addition reactions of unsaturated hydrocarbons and halogens requires a high activation energy.  c)the double covalent bond within unsaturated hydrocarbons requires a lot of energy to break.  d)the double covalent bond within unsaturated hydrocarbons can be broken easily.is: a) when ethane reacts with fluorine gas the product is less stable.
