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.

What is a cholesterol level of 1.85 g/l in the standard units of mg/dl?
sp2606 [1]

Cholesterol is  a sterol, it is a type of lipid molecule, and is biosynthesized by all animal cells. Total cholesterol level lesser than 200 milligrams per deciliter (mg/dL) is considered desirable for an adult. The standard unit used for any substance is gram per liter. However sometimes the concentration can also be expressed in terms of mg per deciliter. In this context 1 gram per liter is equal to 100 milligram per deciliter.

Thus 1.85 gram per liter is equal to 185 mg per deciliter. So 1.85 g/L is equivalent to 185mg per deciliter.

. The net ionic equation for the reaction that occurs during the titration of nitrous acid with sodium hydroxide is (a) HNO2 Na
hjlf

Answer:

H^+_{(aq)}+OH^{-}_{(aq)}\rightarrow H_2O_{(l)}

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Only the species which are present in aqueous state dissociate.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

(a)

The balanced molecular equation will be,

HNO_2_{(aq)}+NaOH_{(aq)}\rightarrow H_2O_{(l)}+NaNO_2_{(aq)}

The complete ionic equation in separated aqueous solution will be,

H^+_{(aq)}+NO_2^-_{(aq)}+Na^+_{(aq)}+OH^{-}_{(aq)}\rightarrow H_2O_{(l)}+Na^+_{(aq)}+NO_2^-_{(aq)}

In this equation the species present are, Na^+\text{ and }NO_2^- are the spectator ions.

Hence, the net ionic equation contains specie is  

H^+_{(aq)}+OH^{-}_{(aq)}\rightarrow H_2O_{(l)}
