Given the reaction: 2 NO2 (g) → N2O4 (g) the rate of reaction was slow with 2.00 moles of NO2 in a 2.00 L container at 1 atm and

285K. Suggest three different ways to increase the rate for this reaction, and explain, with reference to collision theory, how each will alter the rate of reaction.

What is the density of a bar of lead that weighs 173 g and has the following dimensions: l= 2.00 cm, w = 3.00 cm, h = 1.00 in?
oksano4ka [1.4K]

Answer:

\rho=7373.2g/cm^3

Explanation:

Hello!

In this case, since the density is defined as the degree of compactness of a substance, and is defined as the mass over the volume:

\rho= \frac{m}{V}

Given the dimensions of the bar of lead, we can compute the volume as shown below:

V=2.00cm*3.00cm*1.00in*\frac{1in}{2.54cm} \\\\V=2.36cm^3

Thus, the density turns out:

\rho=\frac{173g}{2.36cm^3} \\\\\rho=7373.2g/cm^3

Best regards!

A chemist prepares a solution of iron(II) bromide (FeBr2) by measuring out 46. g of iron(II) bromide into a 400. mL volumetric f
schepotkina [342]

Solution

Given mass of FeBr2 = 85.5 g

Molar mass of FeBr2 = 215.65

No. of Moles of FeBr2 = Given Mass / Molar mass = 85.5 / 215.65

No. of Moles = 0.3964

Given Volume is 450 mL i.e. 0.450 L

Now Concentration = 0.3964/0.450

Hence Concentration = 0.881 mol/L
