A 38.2g sample of hydrogen gas, H, is placed into a 2-L soda bottle. IfI keep the pressure and temperature constant, how large would my container need to be if I increased hydrogen's mass to 50.0-g?

Explanation:

Hello there!

In this case, according to the given problem, it is possible for us to notice that the equation to be used is the Avogadro's one in terms of mass because this is applied to the same gas, hydrogen:

Thus, by considering both the initial and final masses and the initial volume, we can compute the final volume as shown below:

Best regards!

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

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.
