Your friend wants to know if the self heating could be refined so that the reaction releases more energy. Which of the following modifications would test this? (a) adding more of the chemicals in the reaction to the device and seeing if the food stays hot longer (b) changing the material of the can and seeing if the temperature of the food is lower (c) adding an extra layer to the can and seeing if the chemicals still need to mix with the water (d) Removing the compartment that separates the chemicals and the water and seeing how much gas is produced.

Question Hi, I need help with this problem. Please provide answers asap. Thank you. *** 1. One (1) metric ton of Pink Salmon was caught by a commercial fishing vessel. To preserve its freshness, the owner stored it immediately in cold storage facilities at a freezing temperature of -12 deg C from an original temperature of 20 degC. The composition-by-mass of a Pink Salmon is 76.34% water, 19.04% protein, 3.42% fat, and 1.20% ash. The specific heat above freezing of pink salmon can be determined using the formula: Cp = 4.180Xwater + 1.711Xprotein + 1.928Xfat + 1.547XcHO + 0.90Xash, where X is the mass fraction of each solid, decimal, that makes up the Salmon. The Latent heat of fusion of Pink Salmon is 255 kJkg, and the specific heat below freezing is given by the equation: Cp = 0.0.837 +1.256 M, where M is the moisture content, decimal. The initial freezing point of pink salmon is -2 deg C. Given the above information, answer the following questions (Note: Summarize your final answer…
1. Given that body temperature is approximately 37 °C, would the gas produced have a higher pressure inside the body or in a similarly sized container at room temperature? Explain your reasoning. 2. The heat of this reaction is -15.22 kJ. What is the change in temperature of the system? Assume the specific heat of stomach acid is the same as water.
Identify the best heat source for each situation listed: 1. A test tube must be heated to a very high temperature. 2. A test tube needs to be warmed gently to a constant temperature. 3. A flask or beaker must be heated to a very high temperature. Options: a. Clamp in place in a water bath on a hot plate b. Place on a hot plate c. place in a bunsen burner flame I chose 1-a, 2-b, 3-c, but I got none of them right): Please explain.
A student is given a sample of a pink manganese (II) chloride hydrate. She weighs the sample in a dry, covered crucible and obtains a mass of 26.742g for the crucible, cover, and sample. Earlier she had found that the crucible and cover weighed 23.599g. She then heats the crucible to drive off the water of hydration, keeping the crucible at red heat for about 10 minutes with the cover slightly ajar. She then lets the crucible cool and finds it has a lower mass; the crucible, cover and contents then weigh 25.598g. In the process the sample was converted to off-white anhydrous MnCl2. a. What was the mass of the hydrate sample? _ghydrate b. What is the mass of the anhydrous MnCl2? _gMnCl2 c. How much water was driven off? _gH2O d. What is the percent by mass of water in the hydrate? water=massofwaterinsamplemassofhydrateinsample100 _massH2O e. How many grams of water would there be in 100.0g hydrate? How many moles? _gH2O; _molesH2O f. How many grams of MnCl2 are there in 100.0g hydrate? How many moles? What percentage of the hydrate is MnCl2? Convert the mass of MnCl2 to moles. The molar mass of MnCl2 is 125.85g/mol. _gMnCl2; _molesMnCl2 g. How many moles of water are present per mole MnCl2? _ h. What is the formula of the hydrate? _
Answer all the problems below with complete solution, I will rate your answer thank you so much 1. The specific heat of aluminum is 0.89 J/g.oC. How much heat is required to raise the temperature of 16 grams of aluminum from 25 oC to 75 oC? 2. When 198 Joules of heat are added to 5 grams of methane gas at -10oC, the temperature of the methane gas rises to 8oC. Calculate the specific heat of methane gas. 3. When 89.5 Joules of heat are added to a 15.7 gram sample of graphite, its temperature rises from 21.15 oC to 29.13 oC. Calculate the specific heat of graphite.
An 85.0 kg track runner is overheated, and has a core temperature of 42.0 ºC. If I couldlower this athlete’s body temperature back to 37.0 ºC by using their excess heat to boilwater at 100.0 ºC, how many g of water would I need to do this? a) 555.4 gb) 786.8 gc) 1127 gd) 629.5 ge) 1745 g this question has something to do with specific heat someone tried doing (42.0)(85.0x10^3)(42-37) but idk pls help !!
