Answer:

The equilibrium shifts to the left and more of NO₂ is formed.

Explanation:

The Le Chatelier's principle states that when a form of stress is applied to a system in equilibrium, the system shifts so as to relieve that stress.

This principle explains that addition of one of the reactants to a system in equilibrium leads to the equilibrium shifting in such a way that the reaction occurring reduces the concentration of the added reactant.

In this case the addition of dinitrogen tetraoxide increases its concentration and therefore equilibrium shifts to reduce this concentration.

Answer:

According to Le Chatelier’s Principle, a stress placed on a system at equilibrium will cause the equilibrium to shift to counteract the stress.  For example, a temperature increase in the above reaction will favor the reverse reaction to use the excess heat and form brown NO2 gas.  A temperature decrease in the above reaction favors the forward reaction to produce heat and form colorless N2O4 gas.

Describe a mechanical property of steel that characterizes its resistance to permanent deformation
strojnjashka [21]

The mechanical property of steel that characterizes its resistance to permanent deformation is ductility.

Am alloy is a substance prepared by adding one or more elements to a base or parent metal to obtain desirable properties.

Steel is an alloy of Iron and carbon in the composition of 99.8% and 0.2% respectively.

The mechanical or physical properties of steel include:

  • It is more malleable and ductile than iron.
  • It is harder and stronger.
  • it can withstand great stress and strain.

The ductility of a metal like steel is the ability of a metal to change its shape without breaking, that is, resistance to permanent deformation.

Therefore, the mechanical property of steel that characterizes its resistance to permanent deformation is ductility.

At lunch, the babysitter gives Tanya and Damien each a chocolate candy. Tanya puts her candy on her plate. Damien saves his cand
scZoUnD [109]
The correct option is B.
This question is testing your knowledge of the differences between solid and liquid particles. The particles of the solid vibrate around a fixed position, they can not move about while those of the liquid are able to move to some extent. The candy in Damien's pocket melted because it was heated up by the temperature of his body. Because the particles of the chocolate has been heated, they gain more kinetic energy and they vibrate faster compare to that of the solid chocolate.
