Answer:Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).

Answer:
If NH4+ is removed, the reaction will shift toward products to replace the product removed. This means the reaction will shift to the right.
Explanation:
A solution of ammonia NH3(aq) can be written through the following equation:
NH₃(aq) + H₂O(l) ⇌ NH₄⁺(aq) + OH⁻(aq)
If the concentration of one of the reactants changes, the balance will shift in such a way that the change in concentration is counteracted.
If NH4+ is removed, now there is less product, so the reaction will shift toward products to replace the product removed. This means the reaction will shift to the right.
This principle is due to the fact that the equilibrium constant for this reaction is constant at a certain temperature. The ratio of reactants and products is fixed. Any change in concentration disrupts the balance and will result in the balance being restored.

Answer:
Molarity of dextrose = 0.03 mol / L
Explanation:
Given data
mass of dextrose = 5 g
Concentration (Molarity) = ?
Solution
as mass is given so we find out number of moles
<em>Moles = mass / molar mass</em>
Molar mass of dextrose = 180.156 g/mol
Moles = 5 g / 180.156 g/mol
Moles = 0.03 moles
Now we find out molarity
<em>Molarity = moles of solute / Litres of solution</em>
As volume is not given so we suppose it as 1 L
Molarity of dextrose = 0.03 mol / 1 L
Molarity of dextrose = 0.03 mol / L
PV=nRT
Here
P1/T1= P2 / T2
1 torr=133 pascal
600 *133 /215 = 750 *133 / t2
T2= 268.75 K
