Question 2(Multiple Choice Worth 3 points) What happens to the rate of most reactions as the reaction progresses? The rate remai
Sav [38]

Answer: -

The rate decreases as the concentration of the reactants decreases

Explanation: -

A reaction involves change of the reactants into products.

Initially there is only reactants. So the rate if reaction is high.

After some time there are products. So the amount of reactant is less.

Reactions involve collisions of reactant molecules. As the reactant amount decreases, collisions between the reactants decreases. As such the rate of reaction decreases with the progress of the reaction.

The radius of a xenon atom is 1.3×10−8cm. a 100-ml flask is filled with xe at a pressure of 1.2 atm and a temperature of 281 k .
vladimir2022 [97]
Radius of Xenon = 1.3Ă—10â’8 cm 
Volume = 100 ml = 0.1 L 
Pressure P = 1.2 atm = 121.59 Kpa 
Temperature = 281 K 
R = Gas Constant = 8.31 J mol^-1 K^-1 
Now find the number of atoms 
PV = nRT => n = PV / RT 
n = (121.59 x 0.1) / (8.31 x 281) = / 2335.11 = 0.0052 
Number of atoms in a mole is same as Avogadro constant A, which is 6.02 x
10^23 particles.  
n = number of atoms= 0.0052 
N = number of particles 
 Avogadro constant A = 6.02 x 10^23 
n = N/A => N = n x A = 0.0052 x 6.02 x 106^23 = 3.13 x 10^20 
Volume of Xe atom which would be a sphere = (4/3) x pi x r^3 
Volume = = (4/3) x 3.14 x (1.3Ă—10â’8)^3 = 9.2 x 10^-24 
Volume occupied by these particles = n x Volume = 3.13 x 10^20 x 9.2 x
10^-24 = 0.00288
 Fraction of volume will be = 0.00288 / 0.1 = 0.0288

A block of lead displaces 50.5ml of water. The block weighs 698 g. From this
Natasha2012 [34]

Answer:

<h2>13.82 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{698}{50.5}  \\  = 13.8217...

We have the final answer as

<h3>13.82 g/mL</h3>

Hope this helps you
