Explanation:
For the given equation:
NH3 + HCl -> NH4Cl
This is an acid-base reaction (neutralization): NH3 is a base, HCl is an acid and NH4Cl is the sal.
Answer: b) NH3 is the base and NH4CI is the salt.
The equilibria showing how the acetate buffer adjusts to addition of a small amount of NaOH is:
- CH3COOH(aq) + H2O(1) → H30+ (aq) + CH3COO (aq)
<h3>What is a buffer?</h3>
A buffer is a solution which resists changes to its pH when small amounts of strong base or acid is added to it.
Buffers are made from solutions of weak acids and their salts or weak bases and their salts.
The equilibria showing how a buffer made from acetic acid and sodium acetate (NaCH3COO) adjusts to addition of a small amount of NaOH is as follows:
- CH3COOH(aq) + H2O(1) → H30+ (aq) + CH3COO (aq)
Addition of NaOH, a strong base will neutralize the hydronium ion, causing the acetic acid ionization equilibrium to shift to the right to produce more of the acetate ion, the conjugate base.

Explanation:
The ratio of NH3 to NO produced will remain constant since NH3 is the limiting reactant.
Here in this reaction for every 4 moles of ammonia and 5 moles of oxygen gas , 4 moles of NO and 6 moles of water are formed.
So when the amount of oxygen gas is increased to 20 moles without changing the amount of ammonia , the amount of NO formed does not increase as ammonia becomes the limiting reactant.
Answer:
butane will be in gaseous state at 25 degrees and will be solid at -150 degrees.
Explanation:
As 25degrees is the room temperature so the state of butane at 25 degrees will be gaseous while the butane will freeze at -150degrees as it's beyond its melting point, it means it melts at -140degrees , it clearly shows that it exists in solid state before -140degrees.,
175 lbs x ( 1 kg/ 2.2 lbs) = 79.55 kg.
Note that 1 kg = 2.2 lbs
