Chemistry
1 answer:
guapka [62]3 years ago
3 0

Answer:

Shape- square planar , hybridisation-sp3

Explanation:

Shape:

  1. VSPER theorey is used to determine both electron geometry and molecular geometry of a molecule.(PtCl4)2 molecular geometry is square planar
  2. Hybridisation:It undergoes sp3 hybridisation.since there are 2 unpaired electrons in this case, it is paramagnetic in nature

A reaction generates hydrogen gas (H) as a product. The re-
Amiraneli [1.4K]

<u>Answer:</u> The average rate of the reaction is 7.82\times 10^{-3}M/min

<u>Explanation:</u>

To calculate the molarity of hydrogen gas generated, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}

Moles of hydrogen gas = 3.91\times 10^{-2}mol

Volume of solution = 250 mL = 0.250 L    (Conversion factor: 1 L = 1000 mL)

Putting values in above equation, we get:

\text{Molarity of }H_2=\frac{3.91\times 10^{-2}mol}{0.250L}=0.1564M

Average rate of the reaction is defined as the ratio of concentration of hydrogen generated to the time taken.

To calculate the average rate of the reaction, we use the equation:

\text{Average rate of the reaction}=\frac{\text{Concentration of hydrogen generated}}{\text{Time taken}}

We are given:

Concentration of hydrogen generated = 0.1564 M

Time taken = 20.0 minutes

Putting values in above equation, we get:

\text{Average rate of the reaction}=\frac{0.1564M}{20.0min}\\\\\text{Average rate of the reaction}=7.82\times 10^{-3}M/min

Hence, the average rate of the reaction is 7.82\times 10^{-3}M/min

Use the formula: PV=nRT<br><br> If P=12, V=22.4, R=.0821 and T=100, then what would n=?
Lina20 [59]
PV=nRT \\ (12)(22.4)=n(.0821)(100) \\ 268.8=8.21n \\ 268.8/8.21=8.21n/8.21 \\ n=32.74
n ≈ 32.74

How do you calculate the density of a gas, based on its temperature and pressure?
stiks02 [169]
We can rearrange the ideal gas equation:
PV = nRT, where n is the number of moles equivalent to:
n = mass / Mr
PV = mRT/Mr
m/V = PMr/RT
density = PMr / RT; where Mr and R are constant.
