number of protons, neutrons, and electrons for an atom of any element. Atoms are made of protons, neutrons, and electrons. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral.
Hope I helped :)
He is not going back to the school now and I will call him and let you guys help me on the day of my meeting at this point thank him and thank everyone so I’m gonna be back in time to get my hair fixed soon and I’ll get back in the house and I
Explanation:
ΔS denotes change in entropy. Entropy is the degree of disorderliness of a system. An increasing ΔS would mean that the entropy of the products is greater than the entropy of the reactants.
Generally the trend of entropy with state of matter is given as;
Gas > Liquid > Solid (Increasing Entropy)
a. H 2O(g) → H 2O(l)
In this reaction, there is a decreasing ΔS, since we are moving from gas to liquid. This would be the last.
b. 2NO(g) → N 2(g) + O 2(g)
There is an increase in gaseous products. This is definitely an increasing ΔS reaction. This would be the first on the list.
C. MgCO 3(s) → MgO(s) + CO2(g)
The products formed are in solid and gaseous state. There is increasing ΔS but not up to reaction 2.
The order is given as;
b. 2NO(g) → N 2(g) + O 2(g)
C. MgCO 3(s) → MgO(s) + CO2(g)
a. H 2O(g) → H 2O(l)
I BELIEVE THAT VAPORIZATION THAT <span>element or compound is a phase transition from the liquid phase to vapor.
AND
EVAPORATION </span>a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.
Answer : The final volume of gas will be, 103.3 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 740.0 mmHg = 98.4 kPa
Conversion used : (1 mmHg = 0.133 kPa)
= final pressure of gas = 99.3 kPa
= initial volume of gas = 106.0 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
Therefore, the final volume of gas will be, 103.3 L
