Chemistry
1 answer:
OverLord2011 [107]3 years ago
8 0

The answer is;

  1. Melting and boiling points
  2. Unit energy output

These properties are dependent on the chemical composition of the varying hydrocarbons. Coal is a hydrocarbon used in some applications due to its solid nature at room temperatures. The branching of hydrocarbon (cyclic or chain) also determines the energy output on combustion. Gasoline burns more energy than paraffin

What stress would shift the equilibrium position of the following system to the left?
Margarita [4]

Answer:

Heating the system

Explanation:

According to the principle of Le Chatelier, for a system at equilibrium, a specific disturbance would make the equilibrium shift toward the direction which minimizes such a disturbance.

Since we wish to shift the equilibrium to the left, this means we wish to increase the concentration of products, as an excess in their concentration would make the products react and produce more reactants in order to lower the excess concentration of products.

Since heat is also a product, an increase in heat would shift the equilibrium toward the left, as this would consume the excess of heat by producing the reactants.

What begins to happen to radioactive uranium as soon as a mineral containing it crystallizes from magma?
Aleonysh [2.5K]
<span>The radioactive uranium decays into its daughter product, lead. It would do this in magma as well, as nuclear decay depends on forces within the atom, not on the phase of the material in which the atom is a part.</span>
