ow, use the stove to increase or decrease the temperature of the container at 1 atm and then find the state in which the substance exists at the given conditions.You can also refer to the standard states as given in the right-hand side by clicking on the buttons named "Solid," "Liquid," or "Gas" under the panel named "Change State."The following table shows the chemical symbols for the molecules:Molecule SymbolNeon NeArgon ArOxygen O2Water H2OH20 at 120 K, 390Ko2 at 60 K, 150KAr at 32 K , 60 KNe at 26 K and 40 K

A sample of solid silver oxide with a mass of 11.4 grams was reduced to elemental silver by heating under a flow of methane gas, CH4. The reaction produced 10.6 grams of silver. Write a balanced chemical reaction for the reaction between silver oxide and methane gas. The only products formed in the reaction are solid silver metal, carbon dioxide gas, and water vapor. Include the phases of each reactant and product.

Assuming that the natural gas is pure methane, CH4, write a balance chemical equation for the reaction of the natural gas with black copper oxide and red copper oxide. Assume the products are copper metal, water vapor, and carbon dioxide gas include all phases in the reaction.

what amount of heat in J is required to raise the temp of 130.1 g of lead by 20.9 degrees celsius. give answer in standard notation to 0 decimal places

During a recent winter month in Sheboygan, Wisconsin, it was necessary to obtain 3500 kWh of heat provided by a natural gas furnace with 89% efficiency to keep a small house warm (the efficiency of a gas furnace is the percent of the heat produced by combustion that is transferred into the house). (a) Assume that natural gas is pure methane and determine the volume of natural gas in cubic feet that was required to heat the house. The average temperature of the natural gas was 56 °F; at this temperature and a pressure of 1 atm, natural gas has a density of 0.681 g/L. (b) How many gallons of LPG (liquefied petroleum gas) would be required to replace the natural gas used? Assume the LPG is liquid propane [C3H8: density, 0.5318 g/mL; enthalpy of combustion, 2219 kJ/mol for the formation of CO2(g) and H2O(l)] and the furnace used to burn the LPG has the same efficiency as the gas furnace. (c) What mass of carbon dioxide is produced by combustion of the methane used to heat the house? (d)…

You pour a cup of tea that has a volume of 128 mL and is initially 92.1 °C. You place a stainless steel spoon that has a mass of 42.13 g and a temperature of 20.92 °C into the coffee. What is the final temperature °C of the coffee and spoon at thermal equilibrium assuming no heat is lost to the surroundings? Assume the specific heat and density of coffee to be the same as water. The specific heat of the spoon is 0.466 J/g·°C. Report your answer normallly to one decimal place and do not include units.

an important flavor component of vanilla extract is vanillin C8H8O3 molar mass = 152.15 g/mol when vanillin burns in a bomb calorimeter with a heat capacity of 8.60 kJ/°C the temp increases from 25.97°C to 31.18°C. if the heat of combustion of vanillin is -3760 kJ/mol what mass of vanillin (in g) was combusted? answer to two decimal places

The summer before coming to school, you are lucky enough to get a job making coffee at Starbucks,but you tell your parents and friends you have secured a lucrative position as a “java engineer”. An eccentricchemistry professor (not mentioning any names) stops in every day and order 250.0 mL of house coffee at precisely95 °C. He then adds enough milk at 10.0 °C to drop the temperature of the coffee to 90.0 °C. Calculate the amount ofmilk (in mL) the professor must add to reach this temperature. (Assume coffee and milk have the same specific heatcapacity: 4.186 J/g °C. Assume that they also have the same density: 1.000 g/mL).

If the temperature for one of the runs in 52 degrees celcius, what is the 1/temperature(K)y value that will be plotted?
