Which of the following correctly lists the compounds in order of decreasing acidity? A) H2O > HCCH > NH3 > CH3CH3
B) HCCH > H2O > NH3 > CH3CH3
C) CH3CH3 > HCCH > NH3 > H2O
D) CH3CH3 > HCCH > H2O > NH3
E) H2O > NH3 > HCCH > CH3CH3

A) H2O > HCCH > NH3 > CH3CH3

Explanation:

H2O is known as a neural compound which a pH close to 7.0. This however makes it more acidic due to it having the lowest pH when compared to the others in the option.

The other options however have their acidic strength as follows: HCCH > NH3 > CH3CH3. This explains why the pattern of decreasing acidic strength is H2O > HCCH > NH3 > CH3CH3

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
