How many grams of oxygen gas are needed to react completely with 38.442 grams of sulfur dioxide gas? so2(g) + o2(g) --> so3(g) (needs to be balanced)

19.221 grams of oxygen gas are needed to react completely with 38.442 grams of sulfur dioxide gas.

Explanation:

Given :

After balancing,

According to reaction ,2 moles of reacts with one mole of then 1.2013 moles of will react with :

Mass of required =

19.221 grams of oxygen gas are needed to react completely with 38.442 grams of sulfur dioxide gas.

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.
