Mantle convection is a process of that creates circular currents in the asthenosphere. As a result, the plates slowly move.

LUCKY_DIMON [66]

Answer:

<em>Rigid plates that move around Earth's surface is called tectonic plates. </em>

Explanation:

Lithosphere is rigid and relatively cold and is the outer surface of the planet. The convective motions of maintenance break the lithosphere into plates.

This place that a form can move in any direction, can move towards each other, can move away and push each other which is the reason for formation of mountains for shifting of continents for making of ocean basin.

A toy balloon filled with air has an internal pressure of 1.25 atm and avolume of 2.50 L. If I take the balloon to the bottom of

worty [1.4K]

Ideal Gas Law
Given: P1= 1.25 atm P2= 95 atm
V1= 2.50 L

Unknown: V2=?

Formula: V=nRT/P; n = RT / PV

Solution: n = (0.0821 L x atm / K x mol) (285K) / (1.25 atm) ( 2.50L)

= 23.40 / 3.125

Answer: n = 7.49 moles of gas the balloon holds

A metal X loses 2 electrons and a non-metal Y gains 1 electron. Show the electron dot structure of compound formed between them.

Stells [14]

Answer:

The compound is ionic

The compound has a high melting point

The compound will conduct electricity in aqueous solution

The compound will be soluble in water

Explanation:

Now, let us consider the nature of the compound formed when a metal X looses two electrons and a non metal Y accepts one electron.

The compound formed must be ionic in nature with a formula XY2. Ionic compounds are formed by transfer of electrons from metals to nonmetals.

The ionic substance formed is always soluble in water with a high melting point. Usually, ionic solids do not conduct electricity in the solid state because the charge carriers (ions) are tightly bound in the crystal structure while in the solid state. In aqueous solution, the ions are relatively free hence ionic substances conduct electricity in aqueous solution.
