Gaseous ammonia, NH3, is obtained from the reaction of gaseous hydrogen and gaseous nitrogen. According to this reaction, what volume, in L, of nitrogen is required to completely react with 25.0 L of hydrogen under STP conditions? ​

Group of answer choices

8.32 mL

8.32 L

8.20 L

8.00 L

8.33 L .

Explanation:

Hello there!

In this case, according to the given problem, it is possible to firstly write up the undergoing chemical reaction:

Whereas the mole ratio of hydrogen to nitrogen is 3:1. In such a way, given that the mole ratios can be also applied in volume when the temperature and pressure remain unchanged, it is possible to compute the required volume of nitrogen from 25.0 L of hydrogen as shown below:

Best regards!

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
