C_ 1.Over time, all the negative charges in an object, a. remain clustered together where they were placed. b. spread out over a small area on the object. c. spread out over a large area on the object. __b_ 2.When a charged object touches a conductor (like a door knob), a. the positive charges move to the conductor and exit the object. b. the negative charges move to the conductor and exit the object. c. both the positive and negative charges move to the conductor and exit the object. d. neither the positive nor the negative charges move to the conductor and exit the object. 3.Based upon what you saw in this lab, then, it can be said that a. a person cannot be shocked if they have an excess charge on them. b. a person cannot be shocked if they have neutral charge. c. a person can be shocked at any time because it doesn’t depend on the charge the person has.

Naoki's bicycle has a mass of 10 kg. if naoki sits on her bicycle and starts pedaling with a force of 168 n, causing an acceleration of 2.8 m/s2, what is naoki's mass?

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent.true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight.a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol
