An isolated insulated cylinder contains 15.40 grams of neon gas and a 62.30-gram bronze medal in thermal contact. When

the bronze medal was put into the cylinder, its temperature was 72.30°C. The final temperature of both the medal and the

neon gas is 66.30°C. Neon's specific heat capacity is 1.047 joules/gram degree Celsius, and bronze's specific heat capacity is

0.3770 joules/gram degree Celsius. What was the initial temperature of the neon?

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
