we looked at the acrylonitrile molecule, c3h3n, in the previous exercise. which of the following statements about the molecule is or are true? i. the c—c single bond results from overlap between an sp hybrid and an sp 2 hybrid. ii. there are two unhybridized p orbitals on the n atom. iii. all the atoms in the molecule lie in the same plane.

Explain how the integumentary system plays a crucial role in the ability to maintain homeoestasis

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]

Rank the following four acids in order of increasing bronsted acidity : h2f+ , ch3oh, (ch3)2oh+ , ch3sh2+
