Which of the following responses depicts the correct order in which blood is circulated through the body?

An aquarium 5 m long, 3 m wide, and 2 m deep is full of water. Find the work needed to pump half of the water out of the aquarium. (Use the fact that the density of water is 1000 kg/m3, and use 9.8 m/s2 for g.)

Which of the following statements about bond polarity are true? (Select all that apply.)

A bond dipole arrow points toward the more electropositive atom.

A polar covalent bond occurs when electron density in a covalent bond is shared unequally.

An electronegativity difference between 0.4 and 2.0 indicates a polar covalent bond.

A dipole moment exists whenever there is a polar covalent bond.

An electronegativity difference of less than 0.4 indicates an ionic bond.

question (1) indicates bond types. Give the range for (a) anonpolar covalent bond (b) a polar covalent bond (c) an ionicbond
question (2) name and describe the method for lattice enthalpymeasurement

An aquarium 2 m long, 1 m wide, and 1 m deep is full of water. Find the work needed to pump half of the water out of the aquarium. (Use the fact that the density of water is 1000 kg/m³, and use 9.8 m/s² for g.)
