Please help :( Complete the data table using the procedure above and the video provided. To find the distance from the top of the water column to the top of the air column, subtract the height of the water column from the total distance to the top of the air column. Using the equation v = fƛ, determine the wave speed for each trial. Determine an average wave speed by averaging the wave speeds you found for each trial. To calculate the exact value for the speed of sound, use the temperature given at the beginning of the video and the following equation: Vsound = 331 m/s + 0.6(TCelcius) How close was your average speed to the calculation of the actual value for the speed of sound in m/s? Give 2 examples of errors that may have occurred during the lab that could have caused your value to be different than the value that you determined using the equation.

I will mark the brainlest!

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

a corroding iron, if that's one of your choices

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
