You have to find the density of the above, irregularly shaped object: When this plastic toy is measured with a ruler, it is 7.23 cm in height, 5.20 cm wide and 2.25 cm deep. The toy is dropped into a graduated cylinder containing water to a level of 23.9 mL, and it sinks, raising the meniscus to 60.5 mL. Calculate the volume of the toy in mL. Report your answer with units and the correct number of significant digits. g

Which piece of equipment would me most useful for measuring the volume of some water? a. pan balance b. graduated cylinder c. tweezers d. flask quick

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
