The question is What is the root mean square velocity of ammonia molecules (NH3) at 45°C? -My teacher is telling me to use the formula KE=1/2MV^2 to find the velocity and told me to use 45 celcius as the KE and molar mass as M and solve for V^2. (45=17 * V2)

I had to find the root mean square velocity of a gas using the only formula KE=1/2MV^2 . Is this even possible using only this formula?

Water has an extremely high boiling point compared to other compounds of similar molar mass because of ? Hydrogen Bond Adhesive force Covalent bonding Dispersion Forces I believe the answer is A since hydrogen bond is a strong bond and thus require most energy to break them. T...

Would the answer be =1 since tan4.7* cot 4.7 = 1? Thanks

tan4.7 * cot4.7 I understand tan4.7 = 1/ cot 4.7 but I'm stuck after this thanks.

Quotes from wiki "Adhesion is the tendency of dissimilar particles or surfaces to cling to one another" So I'm thinking it is an attractive force? Thanks
Chemistry
What are the attractive forces that increase surface tension? -Would it be cohension and adhension? Thanks

I'm being asked to solve f(4) = f(4-1) + f(4-2). The answers is 3, but I don't know how to get to that answer. Thanks
