For the answer to the questions above,
a) Ag2CO3(s) => Ag2O(s)+CO2(g)
<span>b) Cl2(g)+2(KI)(aq) => I2(s)+2(KCl)(aq) (coefficients are for balanced equation) </span>
<span>net ionic is Cl2(g)+2I- => I2(s)+2Cl-(aq) </span>
<span>c) I2(s)+3(Cl2)(g)=>2(ICl3)
</span>I hope I helped you with your problem
The state in which the forward reaction rate and the reverse reaction rate are equal. Th concentration of chemicals don’t change
Answer:
40 g/mol, Argon
Explanation:
We can find the number of moles of the gas by using the equation of state for an ideal gas:
where
is the pressure of the gas at STP
is the volume of the gas
n is the number of moles
is the gas constant
is the absolute temperature of the gas at STP
Solving for n, we find:
Now we can find the molar mass of the gas, which is given by
where
m = 5.28 g is the mass of the gas
n = 0.132 mol is the number of moles
Substituting,
So, the gas in this problem is Argon, which has a molar mass of 40 g/mol.
This energy required is the latent heat, which is required for physical transformations. Specifically, when it involves changing liquid to gas, this latent heat is called the heat of vaporization. The formula is:
Q = mΔHvap
The molar mass of the compound is
Q = (48.7 g)(31.6 kJ/mol)(1 mol/84.93 g)
<em>Q = 18.12 kJ</em>
