Although it is possible to have more than one state, it is also possible to have only one state.

Explanation:

The mistake Dominic made was stating that "although it is possible to have more than one state, it is also possible to have only one state."

Mixtures are impure substances with the following properties:

  • They have an indefinite composition
  • Their constituents retains their identities.
  • Constituents react differently to changed conditions.
  • They can easily be separated into constituents by physical methods.

There are two types of mixtures based on the number of phases coexisting:

  • Homogeneous mixtures have their constituents existing in just one phase.
  • Heterogeneous mixtures exists in at least two different phases.

The speed of the sound in air at room temperature is 343 m/s. Calculate this speed in miles per hour.
hjlf

Convert metres to feet:

343m*3.28f = 1,125.04ft/s

There are 3600 (60 seconds * 60 minutes) seconds in an hour. Therefore, use this number to convert to an hour.

1,125.04ft*3600s = 4,050,144 ft/h

Now, since you asked for miles, convert to miles (5280 ft in a mile):

4,050,144ft/5,280m = 767.072mph

That is your answer! Hope I helped. :)

Consider the combustion reaction for octane (C8H18), which is a primary component of gasoline.
lesya692 [45]

Answer:

n_{CO_2}=1.93 gCO_2

Explanation:

Hello,

In this case, considering the given chemical reaction, we can use the molar mass of octane (114.23 g/mol) and the 2:16 molar ratio with carbon dioxide to compute the emitted moles of CO2 to the atmosphere via the following stoichiometric procedure:

n_{CO2}=27.6gC_8H_{18}*\frac{1molC_8H_{18}}{114.23gC_8H_{18}}  *\frac{16molCO_2}{2molC_8H_{18}} \\\\n_{CO_2}=1.93 gCO_2

Which also corresponds to the following mass:

m_{CO_2}=1.93molCO_2*\frac{44gCO_2}{1molCO_2} \\\\m_{CO_2}=85.0gCO_2

Best regards.

Consider the following reversible reaction.
dmitriy555 [2]

Answer:

Keq = [CO₂]/[O₂]

Explanation:

Step 1: Write the balanced equation for the reaction at equilibrium

C(s) + O₂(g) ⇄ CO₂(g)

Step 2: Write the expression for the equilibrium constant (Keq)

The equilibrium constant is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It only includes gases and aqueous species. The equilibrium constant for the given system is:

Keq = [CO₂]/[O₂]
