Nitric oxide (NO) is made from the oxidation of NH3 according to the equation
4 NH3 + 5 O2 → 4 NO + 6 H2O .
If an 14.8 g sample of NH3 gives 22.7 g of
NO, what is the percent yield? 1. 72%
2. 87%
3. 98%
4. 100%
5. 22%

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
