A meteorologist predicts fog in the morning over lakes and river bottoms because of the atmospheric conditions and their interactions with the hydrosphere. The hydrosphere is the region on the Earth's surface where the total water on the planet is found. The hydrosphere can be in the form of liquid, vapor, or ice.

Read the information in the table below: Reaction
A Energy to break bonds is more than energy release to form bonds

B Energy to break bonds is less than energy release to form bonds

Which type of reaction is represented by B?
Endothermic reaction
Exothermic reaction
Reaction between liquids
Reaction between solids

Answers

Answer:

Reaction B is exothermic

Explanation:

From the context of thermodynamics, chemical reactions can be broadly classified as endothermic and exothermic reactions.

Endothermic reactions involve absorption of energy and show a positive value for the reaction enthalpy i.e. ΔH is positive. In contrast, exothermic reactions are accompanied by the release of energy and show a negative value for the enthalpy change i.e. ΔH is negative.

In a given chemical reaction energy is required to break bonds and it is released during the formation of new bonds.

The Reaction B is such that, the energy required to break bonds is less than energy released during formation bonds. Therefore, since there is a net release of energy, the reaction is exothermic.

Answers

Marie and Pierre Curie's discoveries included: Polonium and Radium. Marie Curie's death involved her long-term exposure to radiation. I hope this answer helps you on your assignment.

Answer;

  • Radium
  • Polonium

Explanation;

  • Pierre and Marie are known for their work in the study of radioactivity that led to the discoveries of new radioactive elements radium and polonium.
  • Radium element was named after the Latin word ray and Polonium was named after Marie's home country, Poland.
  • Element radium was discovered in the form of radium chloride, that was extracted from uraninite.
