Muzzle velocity is a vector quantity which means it has direction and magnitude. Generally speaking, any velocity is classified as a vector quantity, a value with direction and magnitude. Velocity is the rate of change of the location of the object moving and is specified by its direction and speed. Since muzzle velocity is a velocity then it would surely be a vector quantity. Muzzle velocity is the speed of a bullet as it is leaving a muzzle of a gun in a the direction where the gun is pointed. It would have a value ranging from about 120 m/s to 370 m/s in muskets to 1200 m/s for modern rifles.

How many electrons are in the outermost energy level of an oxygen atom as it shares electrons with hydrogen atoms as part of a w

prisoha [69]

An oxygen atom alone will have 6 valence electrons (outermost electrons). A hydrogen atom each has 1 electron in its outermost shell to share with the oxygen. For oxygen to have a filled outer shell, it will take one electron from each of the two hydrogens into it's outer shell. This means, the number of electrons in its valence shell will be the original amount of electrons oxygen has by itself plus 1 electron from each hydrogen atom. This will form a water molecule $H_2O$
