A compound is 31.1 % S, the rest is chlorine. The compound has a molecular mass of 205.94 amu. What is its molecular formula?

they both have a y in them

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

is there any options? maybe im just not seeing them but i need the options to
