HELPPP!! 7.)Which statement comparing ionic and covalent bonds is correct?
A.) Elements in Group 1A are more likely to form a covalent bonds than ionic bonds with other atoms
B.) The difference between electronegativities is greater for atoms in covalent bonds than for atoms in ionic bonds
C.) More electrons are transferred to form covalent bonds than ionic bonds
D.) Covalent bonds tend to be less polar than ionic bonds

8.)Acid-base reactions can also be classified as which type of reaction?
A.) decomposition
B.) single replacement
C.) synthesis
D.) double replacement

9.) Which statement correctly compares synthesis and decomposition reactions?
A.) Synthesis and decomposition reactions are opposites of each other. Synthesis reactions are in the form A+B—->AB, while decomposition reactions are in the form of AB—-> AB.
B.) Synthesis and decomposition reactions are opposites of each other. Synthesis reactions are in the form AB—->A+B, while decomposition reactions are in the form A+B—->AB.
C.) Synthesis and decomposition reactions are both neutralization reactions. Synthesis reactions are in the form A+B—-> AB, while decomposition reactions are in the form of AB—-> A+B.
D.) Synthesis and decomposition reactions are both neutralization reactions. Synthesis reactions are in the form AB—->A+B, while decomposition reactions are in the form A+B—-> AB.

American eels (anguilla rostrata) are freshwater fish with long, slender bodies that we can treat as uniform cylinders 1.0 m long and 10 cm in diameter. an eel compensates for its small jaw and teeth by holding onto prey with its mouth and then rapidly spinning its body around its long axis to tear off a piece of flesh. eels have been recorded to spin at up to 14 revolutions per second when feeding in this way. although this feeding method is costly in terms of energy, it allows the eel to feed on larger prey than it otherwise could. 1.a field researcher uses the slow-motion feature on her phones camera to shoot a video of an eel spinning at its maximum rate. the camera records at 120 frames per second. through what angle does the eel rotate from one frame to the next? 2. the eel is observed to spin at 14 spins per second clockwise, and 10 seconds later it is observed to spin at 8 spins per second counterclockwise. what is the magnitude of the eels average angular acceleration during this time? 3. the eel has a certain amount of rotational kinetic energy when spinning at 14 spins per second. if it swam in a straight line instead, about how fast would the eel have to swim to have the same amount of kinetic energy as when it is spinning? 4.a new species of eel is found to have the same mass but one-quarter the length and twice the diameter of the american eel. how does its moment of inertia for spinning around its long axis compare to that of the american eel?

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination. at the turning point, how far is the second student from the destination?
