Electrical energy is used to turn the blades of a fan. the amount of energy transformed is seen here: 750 j electrical energy is transformed into 400 j kinetic or mechanical energy. what happened to the remaining 350 j of energy? a) it was lost due to friction. b) it was transformed into 350 j of heat energy. c) it was destroyed by the rotating blades of the fan. d) it was never used and therefore was not transformed.

Which of the following statements is true? a. elements in the last period are radioactive. b. atomic weight is the same as atomic mass. c. elements in the same group have the same number of electron shells. d. atomic number equals the number of neutrons in the nucleus of an atom.

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments, solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
