A sample of an unknown compound is vaporized at 150.°C . The gas produced has a volume of 960.mL at a pressure of 1.00atm , and

it weighs 0.941g . Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound.

Answer:

34.02 g.

Explanation:

Hello!

In this case, since the gas behaves ideally, we can use the following equation to compute the moles at the specified conditions:

PV=nRT\\\\n=\frac{1.00atm*0.960L}{0.08206\frac{atm*L}{mol*K}*(150+273)K} =0.0277mol\\\\

Now, since the molar mass of a compound is computed by dividing the mass over mass, we obtain the following molar mass:

MM=\frac{0.941g}{0.0277mol} \\\\MM=34.02g/mol

So probably, the gas may be H₂S.

Best regards!

A sample of neon gas is at a temperature of 60°C and has a volume of 300 cm. What is the volume of the gas if it is heated to 10
elena55 [62]

Answer:

336.04 cm

Explanation:

T1 = 60+273 = 333K

T2 = 100+273 = 373K

V2 = (V1×T2)/T1

V2 = 300×373/333

V2 = 336.04 cm

If you can answer as many of these as possible that would be great, will give thanks, 5 stars, and brainliest :)
alexandr1967 [171]

Answer:

  1. The nucleus of the atom as suggested by "nuclear" chemistry.
  2. Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons.
  3. An excessive amount of protons or neutrons.
  4. Periodic table, table O, and table N.
  5. Personal opinion question.
  6. The atomic number.
  7. It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge).
  8. Protons ---- element.
  9. Random, self-generated.
  10. Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass.
  11. Neutrons and Gamma radiation.
  12. Gamma radiation.
  13. Electrons and Beta particles.
  14. To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element.
  15. The number of protons because they are what define the identity of an element.

Goodluck!

What is the half-life of A? What will the pressure, initially 32.1 kPa, at
kodGreya [7K]

Answer:

a) 32.09 kPa

b) 32.09 kPa

Explanation:

Given data:

rate constant = 3.56\times 10^{-7} s^{-1}

initial pressure is = 32.1 kPa

half life of A is calculated as

t_{1/2} = \frac{ln 2}{k}

t_{1/2} = \frac{ln 2}{3.56\time 10^{-7}}

t_{1/2} = = 1.956 \times 10^6 s

for calculating pressure we have follwing expression

ln p = ln P_o - kt

P =P_o e^{-kt}

a) P = 32.1 e^{-3.56\times 10^{-7} \times 10} = 32.09 kPa

b) P = 32.1 e^{-3.56\times 10^{-7} \times 10\times 60} = 32.09 kPa
