Answer:
12 atm
Explanation:
First, let us convert Celcius into Kelvin: 28.0 °C = 301.15 K and 129.0 °C = 402.15 K
For this question we must employ the Combined Gas Law: , where is the initial pressure and is the new pressure.
We know that intitially, P=9 atm, V=30 L, and T=301.15K. From our problem, only temperature and pressure changes, while the number of moles, volume and the gas constant, R, stay the same, so they are irrelevant.
Thus, the filled out Combined Gas Law would be:
=, where the volume, moles of gas, and R are cancelled out.
We can manipulate this equation to derive the new pressure. We find that
9atm≈0.74885.
This means that
≈9/0.74885≈12 atm
AgNO₃ + NaCl = NaNO₃ + AgCl↓
c(AgNO₃)=0.04 mol/L
c(NaCl)=0.002 mol/L ⇒ n(AgCl)/L=0.002 mol/L
Ksp=[Ag⁺][Cl⁻]
the solubility of silver chloride
√Ksp=1.34*10⁻⁵ mol/L
n(AgCl)/L>√Ksp the precipitate of silver chloride is formed
Answer: Tin has 48 electrons, 69 neutrons, and 50 protons.
Explanation:
Yes, on one end of an amino acid is an amino group and on the other is a carbonyl group. There is also a hydrogen and an R side chain attached to the central carbon
