If you had 15 molecules of H2 and an unlimited supply of N2, how many

Chemistry
1 answer:
Masja [62]3 years ago
8 0

Answer:

10 molecules of NH₃.

Explanation:

N₂ + 3H₂ --> 2NH₃

As the N₂ supply is unlimited, what we need to do to solve this problem is <u>convert molecules of H₂ into molecules of NH₃</u>. To do so we use the <em>stoichiometric coefficients</em> of the balanced reaction:

  • 15 molecules H₂ * \frac{2moleculesNH_3}{3moleculesH_2} = 10 molecules NH₃

10 NH₃ molecules could be prepared from 15 molecules of H₂ and unlimited N₂.

Acid indigestion is sometimes neutralized with an antacid such as magnesium hydroxide (Mg(OH)2). What products will be released
Lunna [17]

Answer: d) MgCl_2 and H_2O​

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

A neutralization reaction is a double displacement reaction in which an acid reacts with base to produce salt and water. The H^+ ions from water reacts with OH^- ions from base to give water.

2HCl+Mg(OH)_2\rightarrow MgCl_2+2H_2O

Thus products that will be released when the antacid is mixed with the hydrochloric acid in the stomach are MgCl_2 and H_2O​

Al and Bob are arguing about their algorithms. Al claims his O(nlogn)- time method is always faster than Bob's O(n^2 )- time met
pochemuha
Enormous O unpredictability is in reference to the most exceedingly terrible conceivable development rate of the calculation. So O(N log N) implies that it will never keep running in some time more terrible than O(N log N). So in spite of the fact that Al's calculation scales superior to Bob's quadratic algo, it doesn't really mean it is better for ALL info sizes. 
Maybe there is critical overhead in building up it, for example, making a lot of clusters or factors. Remember that even an O(N log N) calculation could have 1000 non settled circles that official at O(N) and still be viewed as O(N log N) the length of it is the most exceedingly awful part.
