Which of the following would shift the following equilibrium system to the right? C2H2(g) + H2O(g) ⇌ CH3CHO(g) Removing H2O(g) f
Fittoniya [83]

Answer:

Adding H₂O(g) to the system.

Explanation:

  • Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.

<u><em>1) Removing H₂O(g) from the system:</em></u>

  • This will decrease the concentration of the reactants side, so the reaction will be shifted to the left side to suppress the removal of H₂O(g) from the system.

<u><em>2) Adding CH₃CHO(g) to the system :</em></u>

  • This will increase the concentration of the products side, so the reaction will be shifted to the left side to suppress the adding CH₃CHO(g) to the system.

<u><em>3) Removing C₂H₂(g) from the system:</em></u>

  • This will decrease the concentration of the reactants side, so the reaction will be shifted to the left side to suppress the removal of C₂H₂(g) from the system.

<u><em>4) Adding H₂O(g) to the system:</em></u>

  • This will increase the concentration of the reactants side, so the reaction will be shifted to the right side to suppress the addition of H₂O(g) to the system.
  • <u><em>So, it is the right choice.</em></u>

Given a magnesium value of 4.5mg/dL, what is the result in SI units?
DaniilM [7]

Answer:

4.5x10^{-5}\frac{kg}{L}

Explanation:

Hello!

In this case, since the density in the international system of units is given in terms of kg for the mass and L for the volume, we need to perform a process of units conversions from mg and dL to kg and L as show below:

4.5\frac{mg}d{L}*\frac{1kg}{1x10^6mg}  *\frac{10dL}{1L} \\\\4.5x10^{-5}\frac{kg}{L}

Best regards!

What did Rutherford's gold foil experiment tell about the atom?​
VLD [36.1K]

The alpha particles that were fired at the gold foil were positively charged. ... These experiments led Rutherford to describe the atom as containing mostly empty space, with a very small, dense, positively charged nucleus at the center, which contained most of the mass of the atom, with the electrons orbiting the nucleus.

hope this helped

How does scientific method help scientists
Irina18 [472]

Scientists use the scientific method all the time to help them understand things about certain topics. The scientific method is a list of steps that are used before, during, and after the experiment. The scientific method can help prove hypothesis about things and can tell you the outcome of the experiment.
