(a) The mass of hydrogen sulfide produced in the reaction is 9.44 g.
(b) Water is the limiting reagent in the given reaction.
<h3>
Mass of hydrogen sulfide produced</h3>
Al2S3 + 6H2O ---> 2Al(OH)3 + 3H2S
mass of water in the reaction = 6(18 g/mol) = 108 g/mol
mass of hydrogen sulfide in the reaction: = 3(34) = 102 g/mol
108 g/mol of H2O ------- > 102 g/mol of H2S
10 of H2O -----------> ?
= 9.44 g
Aluminum sulfide will be completely consumed by the reaction while some fraction of water will remain. Thus, water is the limiting reagent in the given reaction.

Answer:
Depends on different states.
Explanation:
The wavelength of the photon that is emitted from the atom during the transition depends on the transition from different states. If the photon is emitted from n=4 state to n=3 state, the wavelength of photon is 1875 while on the other hand, if the photon is emitted from n=5 state to n=3 state, the wavelength of photon is 1282. If the photon is emitted from n=3 state to n=2 state, the wavelength of photon is 656.
Noble gases tend to not bond with other elements.

Explanation:
Surface area has to do with the number of solid particles that are exposed at a given time and is capable of colliding with other reactant particles. When more surface area is exposed for reaction, then it means that more particles are likely to collide with each other leading to faster chemical reaction rates. When few particles are exposed for reaction (low surface area) then less collisions occur and the rate of reaction is decreased.
Similarly, concentration refers to the amount of substance present. The greater the amount of substance present, the greater the likelihood of collision between particles and the greater the rate of reaction and vice versa.
