A) Find the gas speed of sulfur dioxide at 100.0 degrees Celsius? ______________
gtnhenbr [62]

a. 381.27 m/s

b. the rate of effusion of sulfur dioxide = 2.5 faster than nitrogen triiodide

<h3>Further explanation</h3>

Given

T = 100 + 273 = 373 K

Required

a. the gas speedi

b. The rate of effusion comparison

Solution

a.

Average velocities of gases can be expressed as root-mean-square averages. (V rms)  

\large {\boxed {\bold {v_ {rms} = \sqrt {\dfrac {3RT} {Mm}}}}

R = gas constant, T = temperature, Mm = molar mass of the gas particles  

From the question  

R = 8,314 J / mol K  

T = temperature  

Mm = molar mass, kg / mol  

Molar mass of Sulfur dioxide = 64 g/mol = 0.064 kg/mol

\tt v=\sqrt{\dfrac{3\times 8.314\times 373}{0.064} }\\\\v=381.27~m/s

b. the effusion rates of two gases = the square root of the inverse of their molar masses:  

\rm \dfrac{r_1}{r_2}=\sqrt{\dfrac{M_2}{M_1} }

M₁ = molar mass sulfur dioxide = 64

M₂ =  molar mass nitrogen triodide = 395

\tt \dfrac{r_1}{r_2}=\sqrt{\dfrac{395}{64} }=\dfrac{20}{8}=2.5

the rate of effusion of sulfur dioxide = 2.5 faster than nitrogen triodide

Calcium hydroxide is titrated with nitric acid. What volume of 0.0200 M calcium hydroxide is required to neutralize 35.00 ml of
gogolik [260]

Answer:

43.75 ml

Explanation:

Given that the equation of the reaction is;

2HNO3(aq) + Ca(OH)2(aq) ---> Ca(NO3)2(aq) + 2 H20(l)

Concentration of acid CA= 0.05 M

Concentration of base CB = 0.02 M

Volume of acid VA = 35.00ml

Volume of base VB= ???

Number of moles of acid NA= 2

Number of moles of base NB=1

From

CAVA/CBVB= NA/NB

Making VB the subject of the formula;

VB= CAVANB/CBNA

VB= 0.05 × 35 × 1/ 0.02 × 2

VB=1.75 /0.04

VB= 43.75 ml

How many sodium atoms are present in 0.2310 g of sodium?
umka21 [38]

The number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.

The given parameters;

  • <em>mass of the reacting sodium = 0.231 g</em>
  • <em>1 mole of an atom = 6.02 x 10²³ atoms</em>
  • <em>the atomic mass of sodium is 23 g/mol</em>

The number of moles of 0.231 g of sodium available is calculated as;

no. \ of \ moles = \frac{Reacting \ mass}{Molar \ mass} \\\\no. \ of \ moles = \frac{0.231}{23} \\\\no. \ of \ moles = 0.01 \ mol.

The number of atoms of 0.01 mole of sodium available is calculated as;

1 mole ---------- 6.02 x 10²³ atoms

0.01 ----------------- ?

= 0.01 x 6.02 x 10²³ atoms

= 6.02 x 10²¹ atoms.

Thus, the number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.
