What kind of volcanoes form from subduction boundaries

2 answers:

8 0

Composite volcanoes, stratovolcanoes, form from subduction boundaries.

In subduction zones, an oceanic plate subducts beneath a continental plate. A volcanic arc which is a series of volcanoes can form above the subduction zones where magma forms and rises from the friction of the plates rubbing against each other.

Graduated cylinder is filled to 41.5mL with water, and a price of granite is placed in the cylinder displacing the level to 47.6

Y_Kistochka [10]

Answer:

6.1 cm³

Explanation:

To solve this problem we first need to keep in mind Archimedes' principle:

The volume of water (or any fluid) displaced by a submerged object is equal to the object's volume.

With that in mind we calculate the volume of the granite piece in mililiters:

Volume displaced = 47.6 mL - 41.5 mL = 6.1 mL
Volume of the granite piece = 6.1 mL

Given that one cubic centimeter is equal to one mililiter, the volume of the granite piece in cm³ is 6.1 cm³.

Dehydration is a reversible process. Which of the two set-ups, distillation or

Nata [24]

Answer:

Distillation will generate the most cyclohexene.

Explanation:

Let us assume following attached reaction for the synthesis of cyclohexene from cyclohexanol which attains equilibrium after certain time.

As shown in figure the cyclohexanol upon treatment with phosphoric acid undergoes dehydration reaction (removal of water) and produces cyclohexene. On the other hand cyclohexene reacts with water (hydration reaction) and produces cyclohexanol.

Now, if this reaction is allowed in a single flask it will attain equilibrium and will not generate the cyclohexene in high quantity. On the other hand if we apply Le Chatelier's principle ( removal of product moves the equilibrium in right direction) and distillate cyclohexene (boiling the cyclohexene to convert it into vapors and then collect it after condensation) will move the reaction in forward direction and will allow us to generate cyclohexene in high amounts.

What type of particle has no mass or charge? A) Alpha B) Beta C) Gamma D) Proton

viva [34]

Answer:

Your answer would be C.

Explanation:

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.
