the s.p.h of iron is 0.405 J/g-K. how many joules of heat are needed to raise the temperature of 0.105 kg of Fe from 298K to 361.5K

How many milliliters of 0.524 M HNO3 contain 3.13 g HNO3?

find two numbers such that one of them is five times the other and their difference is 132.

1. What information should a summary include? (Include at least three characteristics of a good summary in your response.) 2. Identify one thing that a summary should not include, and explain why.

(105g)(0.405J/g-K)(361.5K-298K). (105g)(0.405J/g-K)(63.5K)=2700.33J

i still don't understand. especially part a, because element number 116 is not on the periodic table.
