Electrical energy is usually measured in kilowatt-hours, kWh. A Watt is 1 joule per second. A kiloWatt is 1000 joules per second. An hour has 3600 seconds. Therefore 1 kWh = 3.6x106 joules. How many kWh are there in a meal that is 871 Cal, or nutritional calories? Just put in the number. The assumption is the unit is kWh. 1 Nutritional Cal = = 1 kcal (exact) 1 cal = 4.184 joules (exact) kilo 103 (exact) 1 kWh = 3.6x106 joules (exact)

Terephthalic acid, used in the production of polyester fibers and films, is composed of carbon, hydrogen, and oxygen. When 0.6943 g of terephthalic acid was subjected to combustion analysis it produced 1.471 g CO2 and 0.226 g H₂O. If its molar mass is between 158 and 167 g/mol, what is its molecular formula? O C4H6O7 O C4H302 O C7H1204 O C6H805 O C8H604
