Can you please help me understand how to get the answer to this question. A 15.0 g sample of nickel metal is heated to 200 degrees Celsius and dropped into 55.0g of water, initially at 23.0 degrees Celsius. Assuming that all of the heat lost by the nickel is absorbed by the water, calculate the final temperature of the nickel and water. (The specific heat of nickel = 0.444 J/g degrees Celsius)
1 If a 69 kg person ate 165 calories worth of sugar (about the calories in a typical energy drink and they converted all of that energy to heat immediately, what would be the change in temperature of that person? A couple of useful facts for this problem. Food calories are actually kilocalories. 1.000 kilocalorie = 4184 Joule We will assume that the average specific heat of this person's body is 3.00 J/gºC. Enter your answer in ºC with at least 2 sig figs. Just so you are not afraid to eat or drink things, a healthy body is very good at regulating temperature- the bad news is that unless you use it right away, our bodies are very good at converting sugar into fat.
A 125.0 g sample of metal at 85.0°C is placed in 165.0 g of water at 18.0 °C. The temperature of the water rose to 23.3°C. What is the specific heat of the metal? This question has a box to place the question-answer, but you will not get any points unless you show your work on your piece of scrap paper. Show the answer with units on the scrap paper. The specific heat of water is 4.184 J/g°C
Carbohydrates serve as a vital source of chemical energy to the human body. Carbohydrates are broken down into smaller units of glucose, among other sugars, providing energy to various muscles and organs, including the brain. On average, for every 9.00 g of carbohydrates consumed, the body will store 153 kJ of energy. Convert this energy value to kilocalories (kcal). 153 kJ = kcal
Joules (J) are a measure of energy. Chemists often measure energy in calories (cal). If 1 cal = 4.184 J, how many cal are equivalent to 48.3 J?
Expressing amounts of energy in different energy units is necessary to solve many chemistry problems. For practice, complete the following table. The Joule (J) is the SI unit of energy. 1 calorie (cal) = 4.184 J J cal kJ 549 197 0.806
A calorimeter is charged with 59.197 mL of water at 24.2 °C. After a reaction takes place in the calorimeter, the water temperature is 25.2 °C. How much heat did the reaction produce, and was it exothermic or endothermic? (The density of water is 1.00 g/mL.)
Lana is using a calorimeter to determine the specific heat of a metallic sample. She measures out 194.0 grams of her metal and heats it to 86.3 degrees Celsius. Then, she puts the sample into a calorimeter containing 13.91 grams of water at 44.2 degrees Celsius. She measures the temperature of the water in the calorimeter until the number stops changing, then records the final temperature to be 67.3 degrees Celsius. What is the specific heat of the metal? Please answer to three digits after the decimal point and include units.
