Ice starts to melt and turns into water as it melts
<h2>
Hello!</h2>
The answer is:
The new volume is 2.84 L.
<h2>
Why?</h2>
To solve the problem, we need to remember what STP means. STP means that the gas is at standard temperature and pressure, or 273.15 K (0°C) and 1 atm.
Also, we need to use the Combined Gas Law, since the temperature, the pressure and the volume are being changed.
The Combined Gas Law establishes a relationship between the temperature, the pressure and the volume of an ideal gas using , Gay-Lussac's Law, Charles's Law, and Boyle's Law.
The law is defined by the following equation:
Where,
is the first pressure.
is the first volume.
is the first temperature.
is the second pressure.
is the second volume.
is the second temperature.
So, we are given the following information:
Then, isolating the new volume, and substituting, we have:
Hence, the new volume is 2.84 L.
Have a nice day!
Answer:-
H2SO3 (aq)
Explanation:-
NaCl, KOH and HCl ionic compounds.
Ionic compounds dissociate into ions in water.
Ions can carry electricity in water. So NaCl, KOH and HCl are all strong electrolytes.
H2SO3 is not a strong acid and dissociates to a small extent into ions in water.
Hence number of ions formed is less. Hence it is a weak electrolyte.
Cutting of Nails is a Physical Change since no new substance is formed.
Don't confuse it with Reversible and Irreversible Changes
Answer:
The NaCl concentration will be 0.03 M.
Explanation:
Given data:
Initial volume = V₁ = 56.98 mL (56.98/1000 = 0.05698 L)
Initial concentration = M₁= 0.5894 M
Final volume = V₂= 1.20 L
Final concentration = M₂= ?
Solution:
By diluting the solution volume of solution will increase while number of moles of solute remain the same.
Formula:
Initial concentration × Initial volume = Final concentration × Final volume
M₁V₁ = M₂V₂
M₂ = M₁V₁ / V₂
M₂ = 0.5894 M × 0.05698 L / 1.20 L
M₂ = 0.0336 M /1.20
M₂ = 0.03 M
