Oceanic crust is frequently pushed into the mantle near convergent plate borders, where it starts to melt. Granite, the rock that forms the continents, is formed as magma rises into and through the other plate.

Therefore, at convergent borders, oceanic and continental crust are annihilated.

<h3>What is a diverging plate boundary?</h3>

When plates are spreading apart, new oceanic crust is being created to fill the space left behind. Most divergent boundaries are observed around mid-ocean oceanic ridges (although some are on land).

The mountains would keep eroding over the next few million years, but since there wouldn't be any tectonic activity to renew them, they would gradually erode down to low rolling hills. This would result in far less fascinating geography and a flatter planet overall.

The reaction of solid aluminum with hydrochloric acid is used to make hydrogen gas in a laboratory experiment. The reaction is 2

Gemiola [76]

Answer:

0.003088 moles of hydrogen gas were formed .

Explanation:

Pressure at which hydrogen gas is collected at 20°C = 768.0 Torr

Vapor pressure of water at 20°C = 17.5 Torr

Total pressure = Vapor pressure of water + Partial pressure of hydrogen gas

Partial pressure of hydrogen gas:

Total pressure - Vapor pressure of water

= 768.0 Torr - 17.5 Torr = 750.5 Torr = 0.987 atm

(1 Torr = 0.001315 atm)

Pressure of hydrogen gas =P = 0.986 atm

Temperature at which gas was collected ,T= 20°C = 293.15 K

Volume of the gas ,V= 75.3 mL = 0.0753 L

Moles of hydrogen gas = n

PV=nRT (An ideal gas equation)

$n=\frac{PV}{RT}=\frac{0.987 atm\times 0.0753 L}{0.0821 atm L/mol K\times 293.15 K}=0.003088 mol$

0.003088 moles of hydrogen gas were formed .
