Consider this reaction:PCl5(g) + heat PCl3 (g) + Cl2 (g)
What will happen when the pressure is decreased?
There will not be a shift in equilibrium.
There will be a shift toward the products.
There will be a shift toward the reactants.
There is not enough information to make a prediction.

Answers

The answer is There will be a shift toward the products.

To solve this problem, it is necessary to understand Le Chatelier's principle. According to the principle, if a chemical reaction undergoes changes in conditions, the chemical equilibrium will shift in order to undo the effects. In the reaction PCl5(g) + heat ↔ PCl3 (g) + Cl2 (g), when pressure is decreased, the system will try to increase it. This will result in the increase of gaseous pressure, so the equilibrium will be shifted toward the products.

A pedigree chart can show a trait that is: dominant, a mutation, both dominant and a mutation

Answers

Answer;

both dominant and a mutation

Explanation;

  • Pedigree charts shows inheritance of a certain trait over generations. A pedigree can therefore track an inherited trait through several generation.
  • A dominant trait is an inherited trait that appears in an offspring if it is obtained from a parent through a dominant allele. Such a trait is seen when heterozygous genotype is present. If a trait is dominant, then its appearance on a pedigree chart will be such that it appears in every single generation.
  • Mutation refers to sudden spontaneous changes that occurs randomly in the genome of an organism. Mutations may also be observed in a pedigree chart.
