Answer:
True
Explanation:
If you look closley at the nucleus, you don't count the neutrons just the prtons which then effect the electrons.
Good luck :)
Answer:
The heat produced is -15,1kJ
Explanation:
For the reaction:
2SO₂+O₂ → 2SO₃
The enthalpy of reaction is:
ΔHr = 2ΔHf SO₃ - 2ΔHf SO₂
As ΔHf SO₃ = -395,7kJ and ΔHf SO₂ = -296,8kJ
<em>ΔHr = -197,8kJ</em>
Using n=PV/RT, the moles of reaction are:
= <em>0,153 moles of reaction</em>
As 2 moles of reaction produce -197,8kJ of heat, 0,153moles produce:
0,153mol×
= <em>-15,1kJ</em>
<em></em>
I hope it helps!
Answer: Synthesis/ Combination
reaction
4 Al + 3S2 => 2 Al2S3
Explanation: The equation is now balanced the amount of each individual atom in both the reactant and product sides are equal.
Answer:
![V=22.4L](https://tex.z-dn.net/?f=V%3D22.4L)
Explanation:
Hello,
In this case, by using the ideal gas equation, er can compute the volume of fluorine gas as shown below:
![PV=nRT\\\\V=\frac{nRT}{P}=\frac{1mol*0.082\frac{atm*L}{mol*K}+(0+273)K}{1.00atm} \\\\V=22.4L](https://tex.z-dn.net/?f=PV%3DnRT%5C%5C%5C%5CV%3D%5Cfrac%7BnRT%7D%7BP%7D%3D%5Cfrac%7B1mol%2A0.082%5Cfrac%7Batm%2AL%7D%7Bmol%2AK%7D%2B%280%2B273%29K%7D%7B1.00atm%7D%20%20%5C%5C%5C%5CV%3D22.4L)
Best regards.
