Complete Question

The complete question is shown on the first uploaded image

Answer:

The pressure is  P  = 0.76 \ atm

Explanation:

From the question we are told that

   The mass of the carbon monoxide  is  m_c  =  17 \ g

   The temperature at which takes place  T  = 30 .0^oC =  30 + 273 =  303 K

   The volume of the sealed vessel  is  V  =  20 .0L

Generally the ideal gas law is mathematically represented as

        PV  =  nRT

Where R is the gas constant with value  R =  0.0821  \ L \ atm \ mol^{-1} K^{-1}

n is the number of moles of carbon monoxide  which is mathematically evaluated as

             n =  \frac{m_c}{M_c}

where M_c is the molar mass of carbon monoxide which is a constant with value

        M_c  =  28 \ g/mol

So     n  =  \frac{17}{28}

         n  =0.6071

Now Making P the subject we have

           P  =\frac{ 0.6071 * 0.0821 * 303}{20}

           P  = 0.76 \ atm

Properties of substances can be classified as physical or chemical properties. Which statements describe chemical properties? (C
Tamiku [17]

The correct answers are options C, that is, silver tarnishes and becomes black when exposed to oxygen, and option E, that is, diesel fuel burns when it is heated.  

Chemical changes refer to the modifications in which the chemistry at molecular level is modified as the initial substance gets transformed into a new and different final substance. This change occurs with the dissociation of old bond and production of new bonds respectively.  

Silver gets tarnished and becomes black when exposed to oxygen. This refers to a chemical change as silver a white and lustrous substance gets transformed into a tarnish black final substance. However, silver does not easily react with oxygen at usual circumstances. It easily reacts with sulfur comprising components in the air and generates black compound as Ag₂S.  

Burning of diesel fuel when it is heated. Diesel refers to a mixture of hydrocarbons varying approximately from C₁₀H₂₀ to C₁₅H₂₈. When these hydrocarbons get burnt they generate novel substances, that is, carbon dioxide and water. Hence, it is also a chemical reaction.

What will be the pH of a buffer solution containing an acid of pKa7.5, with an acid concentration exactly one fourth of that of
I am Lyosha [343]

Answer: pH of buffer solution is 8.1

Explanation:

The formula for the Henderson–Hasselbalch equation is:

pH=pK_a+\log\frac{[A^-]}{[HA]}

pH is the concentration of [H^+]

pK_a is the acid dissociation constant,

A^- and HA are concentrations of the conjugate base and starting acid.

Putting in the values we get:

pH=7.5+\log\frac{x}{\frac{x}{4}}

pH=8.1

Thus pH of buffer solution is 8.1

If 9.6 X 1021 molecules of hydrogen are reacted with excess nitrogen, how many liters of ammonia can be produced at STP?
diamong [38]

The volume of NH₃ produced at STP : 0.237 L

<h3>Further explanation</h3>

Reaction

N₂ + 3H₂ → 2NH₃

1 mol = 6.02 x 10²³ particles

9.6 X 10²¹ molecules of Hydrogen, mol :

\tt \dfrac{9.61\times 10^{21}}{6.02\times 10^{23}}=1.596\times 10^{-2}~moles

mol H₂ : mol NH₃ = 3 : 2

mol NH₃ :

\tt \dfrac{2}{3}\times 1.596\times 10^{-2}=0.0106

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). <em>At STP, Vm is 22.4 liters/mol.</em>

The volume of NH₃ :

\tt 0.0106\times 22.4=0.237~L
