Abattery has chemical energy, which can be used to generate thermal and radiant energy in a lightbulb. which best explains what happens to the amount of energy in this scenario? -the total energy in the system increases because chemical energy creates thermal and radiant energy. -the total energy in the system decreases because chemical energy disappears as thermal and radiant energy are generated. -the total energy in the system remains the same as the decrease in chemical energy equals the increase in thermal and radiant energy. -the total energy in the system remains the same as the increase in chemical energy equals the decrease in thermal and radiant energy.

Select the correct answer. given: 2libr + ba → babr2 + 2li in this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced? a. 1.18 mol b. 2.37 mol c. 4.73 mol d. 16.4 mol e. 32.9 mol

When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced. be sure your answer has the correct number of significant digits.
