During lab you measured the ph of mixtures containing strong acid and strong base. write net brønsted equations that show the acid-base reactions of common household items. for polyprotic species (such as vitamin c, lemon juice, and washing soda), show only one proton transfer. remember that spectator ions are not included. (use the lowest possible coefficients. omit states-of-matter in your answer.)

Clara solved the equation 7/3x = −2/3 as shown → 7/3x( 3/7 ) = −2/3 ( 3/7 ) x = −14 what is clara’s error?

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.

Ineed with question three. i don't understand how i'm supposed to achieve 3 marks.
