Answer:

248.4 mL

Explanation:

In order to answer this problem we can use <em>Boyle's law</em>, which states that at a constant composition:

  • P₁V₁ = P₂V₂

Where in this case:

  • P₁ = 762.7 torr
  • V₁ = 229.5 mL
  • P₂ = 704.5 torr
  • V₂ = ?

We <u>input the data</u>:

  • 762.7 torr * 229.5 mL = 704.5 torr * V₂

And <u>solve for V₂</u>:

  • V₂ = 248.4 mL

What must be true about two objects if heat is flowing between them?
Degger [83]

The objects may exchange heat between each other if they are in contact with each other.

The two objects will allow flow of heat between them if they have a difference in temperature from each other.

The heat will flow from higher temperature object to lower temperature object. The will reach a final temperature (common to each other) and then there will be no heat transfer between each other.

Why are the optimum conditions for the Haber process a temperature of 450°C and pressure of 200 atmospheres?
Novay_Z [31]

Answer:

See explanation.

Explanation:

Hello,

Haber process is defined as the widely acknowledged productive process of ammonia by the reaction:

N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)

Which is carried out in gaseous phase. Thus, by means of the Le Chatelier's principle, it is possible to know that its standard enthalpy of reaction is -45.90 kJ/mol (NIST webbook) for which it is an exothermic chemical reaction, for that reason less ammonia will be produced at high temperature, nonetheless, the temperature should not be too low since the reaction rate significantly decrease, therefore, the optimum found temperature is 450 °C.

Moreover, since there are more moles (3+1=4) at the reactants and less moles at the products (2), increasing the pressure of the reaction increases the yield of ammonia, nonetheless, higher pressures involve the purchasing of more expensive equipment to withstand the high-pressures, for that reason, the best found pressure has been set as 200 atm.

Best regards.

A gold ring contains 3.2 grams of pure gold. how many moles of gold are in the ring?
mamaluj [8]

Answer:

0.0162 moles (3 s. f.)

Explanation:

moles = mass / Ar

moles = 3.2 / 197.0

moles = 0.0162436

moles = 0.0162 (3 s. f.)
