Two different metals, each with a mass of 50.0g, are placed so they directly touch each other. Metal A has a higher initial temperature than Metal B. You calculate the value of q (the heat content) of Metal A correctly as 300 calories. Which statement is true about the heat flow between metal A and Metal B, assuming there is no other heat loss? • Metal A will gain 300 calories and Metal B will lose 300 calories
• Metal A will lose 300 calories and Metal B will gain 300 calories
• Metal A will gain 200 calories and Metal B will lose 100 calories
• Metal A will lose 200 calories and Metal B will gain 100 calories

Choose all the answers that apply. as ocean depth increases, temperature decreases temperature increases pressure increases pressure decreases salinity increases density increases

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
