<span>True

Petroleum and coal can be mined from the continental shelf. Hot magma from inside the Earth seeps out from the crevices in the mid-ocean ridge. There is speculation regarding whether this is a cost-effective technique. Fossil fuels and mineral deposits can be located all throughout the continental shelf and also in some of the deepest depths of the ocean.</span>

Answer:The given statement is true.

Explanation:

Continental Shelf: A portion of continent submerged under the relative shallow ocean water.Most of the gradually slopes down in to the water.

The relatively flat surface and shallow water makes it fitr place to harvest sea food, non renewable energy resources like : coal, petroleum .

C. Magma from venus mantle erupted as lava.

Explanation:

A volcano is a land form which results from the eruption of molten rocks (lava) on the surface. Volcanic rocks are a special type of igneous rock that forms when molten rock cools and solidifies on the surface.

For a planet like Venus which is presently not active and little to no movement occurs within the plates, the volcanisim must have occurred when the planet was relatively young and it must have been millions of years ago.

It is widely believed that Venus was geologically active in times past. Mantle generated lava must have solidified on the surface in times past to have formed the volcano.

Evaluating other options:

Impact of space objects on Venus would lead to the formation of a crater which is a depression on the surface. The rock would be mostly metamorphic.

If water was ever present in Venus, they would have produced sedimentary rocks instead. The erosive power of water is not high enough to cut through the crust. Also, water would not aid the formation of volcanoes.

Heat is not enough to from volcanoes. Other factors are also in play.

There are approximately 15 milliliters (mL) in 1 tablespoon (tbsp). Which expression can be used to find the approximate number
Helga [31]
You know 1 tbsp is 15 milliliters so you would multiply 15 and 3 together. 15 x 3 =45
So there are 45 milliliters in 3 tbsp.

Write a balanced half-reaction for the product that forms at each electrode in the aqueous electrolysis of the following salts:(
likoan [24]

Balanced Half reactions are:

At anode 2Cl^{-}  ==> Cl₂+ 2e^{-} + H₂O ==> ClO^{-}+ 2H^{+} + Cl^{-}

At Cathode:  2H^{+} + 2e^{-} ==> H₂

Since the question states that you are using an aqueous solution of MnCl₂,  so ions will have present are, H₂O, H^{+}, Mn^{2+} and Cl^{-}

Now at Anode reaction will occur as given:

2Cl^{-}  ==> Cl₂+ 2e^{-} + H₂O ==> ClO^{-}+ 2H^{+} + Cl^{-}  (will occur)

At Cathode:

2H^{+} + 2e^{-} ==> H₂ (will occur)

At Cathode:

Mn^{2+} +  2e^{-}==> Mn (This reaction will not occur)

The deposition of solid Mn will not occur because in aqueous solution, H^{+}will be reduced before Mn^{2+} .

The reduction potentials for H^{+} is zero whereas reduction potential for Mn^{2+} is - 1.18V.

The reduction potential of a species is its tendency to gain electrons and get reduced. It is measured in millivolts or volts. Larger positive values of reduction potential are indicative of a greater tendency to get reduced.

you fill a rigid steel container that has a volume of 20 L with nitrogen gas to a final pressure of 2 x 10^4 kpa at 23 Celsius.
garik1379 [7]

Answer:

4.549 kg.

Explanation:

  • We can use the general law of ideal gas: <em>PV = nRT.</em>

where, P is the pressure of the gas in atm (P = 2 x 10⁴ kPa/101.325 = 197.4 atm).

V is the volume of the gas in L (V = 20.0 L).

n is the no. of moles of the gas in mol (n = ??? mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of the gas in K (T = 23° C + 273 = 296 K).

<em>∴ n = PV/RT =</em> (197.4 atm)(20.0 L)/(0.0821 L.atm/mol.K)(296 K) = <em>162.5 mol.</em>

  • To find the mass of N₂ in the cylinder, we can use the relation:

<em>mass of N₂ = (no. of moles of N₂)*(molar mass of N₂) = </em>(162.5 mol)*(28.0 g/mol) = <em>4549 g = 4.549 kg.</em>
