A 20.0 g lead ball is heated in a Bunsen burner to 705 degrees celsius. It is then dropped into a 500.0 g water bath. What is the initial temperature of the water if the final temperature is 35 degrees celsius? The C of lead is 0.13 J/g degrees C. [ Remember: Ch2o = 4.18 J/g degrees celsius]

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
