I need all questions answered please thank you so much
Reactions are classified as either exothermic or endothermic. Exothermic reactions feel hot (e.g., a burning campfire), whereas endothermic reactions feel cool (e.g. squeezing an instant cold pack). A thermometer measures the temperature of the surroundings in a calorimeter to determine the amount of energy being transferred by the system. Water molecules speed up when they gain heat and slow down when they lose heat; note that you can track both the cold and hot water molecules in the simulation based on the shade of red of the larger central oxygen atom by checking the box labeled Show microscopic view. Select the Experiment tab in the simulation, and then click Run Demonstration. When observing the simulation, pay particular attention to the temperature change and movement of the molecules by clicking Show microscopic view when HCl and NaOH neutralize each other in the fourth experiment. Use your observations to complete the following sentences. Match the words in the left column to…

Ignition wires heat Thermometer Stirrer A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of sample fuels and the energy content of foods. In an experiment, a 0.5650 g sample of quinizarin (C14H804) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.187×103 g of water. During the combustion the temperature increases from 23.98 to Water 26.55 °C. The heat capacity of water is 4.184 J gloC1. The heat capacity of the calorimeter was determined in a previous experiment to be 770.8 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of quinizarin based on these data. C14H804(s) + 1402(g) → 4 H20(1) + 14 CO2(g) + Energy Sample dish Burning sample Steel bomb Insulated outside chamber Molar Heat of…
