The answer would be:

Oceanic-Oceanic Convergent Plate

This is why:

When two oceanic plates collide, the heavier of the two would subduct or in other words, go under the other plate. When this happens, ocean trenches and volcanic arcs form. The trench forms at the point oceanic plate goes under the other plate. And above the other plate that goes over create volcanic arcs.

how does increasing concentration/ temperature/ surface area affect the yield of products in a chemical reaction (not reversible
egoroff_w [7]
Answer:
             <span>Increasing concentration, temperature and surface area will increase the yield of products.

Explanation:
                   Concentration:
                                           
Increase in concentration of reactants will increase the number of reactants per unit volume. Therefore, the probability of collisions will increase hence, it will result in the increase in yield.

                   Temperature:
                                        Increase in temperature increases the kinetic energy of reactants. Therefore, the increase in velocity of reactants results in the collisions with high energy. It makes it feasible for reactants to attain the optimum energy (activation energy) to convert into products with good yield.

                  Surface Area:
                                       The reactants in grinded / powder form reacts fast as compared to solid form. In fact, grinding results in increase of the surface area of reactants. Greater surface area increases the probability of reactants to colloid. Hence, increases the yield.</span>

The research of astronomy during the time period of 1970 - 1990 is given below:

<u>Date</u>                                                   <u>Event</u>

1. 15 June 1974               Black Brant VC sounding rocket from White Sands.

2. 14 May 1973              Launch of Skylab, the USA's first space station

3. 26 July 1971           Launch of Apollo 15

<h3>What is Astronomy?</h3>

This refers to the branch of science that deals with celestial bodies and their relation to each other.

Hence, from information about astronomy, between the time period 1970 - 1990 as it was on the 26th of December, 1974 that the Soviet space station Salyut-4 was launched.

The event I think had the greatest impact in astronomical history during this time period was the launch of Apollo 16.

The osmotic pressure of a solution increases as
s344n2d4d5 [400]
The osmotic pressure of a solution is a colligative property, which means that it depends on the number of particles of solute in the solution.

Formula: Osmotic pressure = MRT, where M is the molarity of the solution, R is the universal constant of ideal gases and T is the absolute temperature of the solution.

So, the answer is the option .: the osmotic pressure of a solution increases as the number of particles of solute in the solution increases.

The number of electrons in n=1 and n=2 shells of aluminum are
harina [27]

Answer:

n=1 holds two electrons and n=2 holds eight electrons.

Explanation:

Hello

In this case, since the atomic number of aluminum is 13, its electron configuration is:

Al^{13}: 1s^2,2s^2,2p^6,3s^2,3p^1

In such a way, we can see that the level n=1 is filled with two electrons since the subshell s is able to hold two electrons and the level n=2 is also filled but with eight electrons as s holds two whereas p holds 6. Moreover, n=3 is holding three electrons.

Best regards.
