The correct answer is C. Water has a higher boiling point than expected because hydrogen and oxygen form single covalent bonds. Molecules of water is bound together by strong attractions which needs high energy to break resulting to a higher boiling point of water than most substances.

Which of these events is caused by contact forces?
harkovskaia [24]

Earthquakes along the San Andreas fault in California.

<u>Explanation</u>:

  • When the two plates collide with each other, earthquakes occur. The contact between them makes this earthquake possible. The contact forces are responsible for the earthquakes as there is contact between two plates.          
  • The gravitational force is a force that is responsible for elevated tides happening on the east coast or the Jupiter's moons to remain in orbit. But this is not a contact force as there is no contact between them
  • Moreover, Without any contact, the magnetic force is a non-contact as it attracts the pins from a distance.

Pls help, How is stoichiometry used to calculate amounts of substances in a chemical reaction?
Elden [556K]

Answer:

Thus, to calculate the stoichiometry by mass, the number of molecules required for each reactant is expressed in moles and multiplied by the molar mass of each to give the mass of each reactant per mole of reaction. The mass ratios can be calculated by dividing each by the total in the whole reaction.

Explanation: Stoichiometry is the field of chemistry that is concerned with the relative quantities of reactants and products in chemical reactions. For any balanced chemical reaction, whole numbers (coefficients) are used to show the quantities (generally in moles ) of both the reactants and products.
