When discussing discordant and harmonious sound waves, the statement tat is false is : if the original waves combine to form irregular displacement of air, the sound will be discordant. The fact is, irregular displacement of air does not guarantee sound discordance

Answer is: a. Mg + 2HCl → H₂ + MgCl₂.
Reduction hald reaction: 2H⁺ + 2e⁻→ H₂.<span>
Oxidation half reaction: Mg</span>⁰ → Mg²⁺ + 2e⁻.
In this chemical reaction, magnesium lost two electrons (oxidation, change oxidation number from 0 to +2) and hydrogen gain that two electrons (reduction, change oxidation number from +1 to 0).
The Answer Is C, Hope It Helps
Answer:
the new volume is 1.35L
Explanation:
The computation of the new volume in the case when the temperature rises to 45 degrees is shown below:
GIven that
Volume = 1.25L
And, the temperature is 22 degrees celsius
So,
= (275 + 22)k
= 297 k
Now
= (275 + 45)k
= 320 k
Now as it is a constant pressure
So, the new volume is

= 1.35L
hence, the new volume is 1.35L
