A proper fuel-air mixture is most critical in the production of an efficient, nonluminous flame. For the ignition of an efficient Bunsen burner flame in the laboratory, identify the (most common) fuel and the required air component

When using a coffee cup calorimeter to determine the specific heat of a metal sample errors can occur in the procedure.  Which of the following procedural errors would lead to a specific heat value being calculated that is lower than the accepted value?  Check all that apply.   When the metal was placed into the coffee cup calorimeter some water splashed out of the cup.         After the metal was heated (to its initial temperature) there was a significant time delay before it was placed into the coffee cup calorimeter.         After the mass of water in the coffee cup calorimeter was measured and recorded some of the water evaporated.         The lid was not placed on the coffee cup calorimeter during the experiment.         The mass of the metal was measured incorrectly. The actual mass of the metal used was greater than what was recorded.         The "final" temperature was read before the metal and water had reached equilibrium         The calorimeter used in…

The quartz sample starts off alo insulated container at 90.2 °C and the temperature of the water starts off at 24.0 °C. When the temperature of the water stops changing it's 29.6 °C. The pressure remains constant at 1 atm. water Calculate the specific heat capacity of quartz according to this experiment. Be sure your answer is rounded to 2 significant digits. sample a calorimeter J ?

Use the equation for heat absorbed/lost to calculate the answer to the below question.  Show as much work as possible and make sure to put the correct answer (with units) in the box provided. Equation: Q=mc△TQ=mc△T A 500.0 g piece of aluminum at 100° C is placed in 300ml of water. While in the water, the aluminum then cools to 30°C.  Calculate the amount of heat lost by the aluminum. The specific heat of water is 4.18 J/g ∘∘C and the specific heat of aluminum is 0.90 J/g ∘∘C Remember:  One ml = one gram.     Neat handwriteing pleasee thank youuuu
