<span>Conduction of electricity takes place when there are ions in the medium. The pure water has no ions to conduct electricity. When it has dissolved ions it will conduct electricity. In the case of dry soil it is very resistive to electricity. But when wet it has ions in water molecules among the soil particles. Then the soil becomes a conductor of electricity.</span>

In dry soil there is electrolyte (<span>substance that produces an </span>electrically<span> when dissolved in a polar solvent), but that electrolyte is not dissolved, to produce electricity free ions are needed. In pure water there is a very small amount of ions (H</span>⁺ and OH⁻). In wet soil d<span>issolved electrolyte separates into </span>cations<span> and </span>anions, <span>movement of anions and cations in opposite directions make current.</span>

Why is an alkali metal element like sodium (Na) so reactive?
guapka [62]
Alkali metals are known for being some of the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and often have an oxidation state of +1. These metals are characterized as being extre

torisob [31]
<span>1)false a in chemical equilibrium concentration of reactant is equal to concentration of product
 2)as here they said heat is added in product side means its endothermic reaction and in endothermic reaction on increasing temp. equilibrium shift towards forward direction so its true
 3) B)as here mole are equal in reactant and product side that is 2 and if we increase pressure equilibrium shift in dat direction where no. of moles are less and here mole are equal so it will remain unaffected</span>

Some thermodynamic properties of ethanol are listed in the table. Thermodynamic Properties Property Value c (solid) 0.5 J/g °C c
alexira [117]
<h2>Answer </h2>

Option C - 320J

<u>Explanation </u>

Since ethanol solid at −120 °C and is only cooling down (it won’t change states) . The amount of Thermodynamic properties values c is given in form of solid, liquid and gas. Amount of energy released is calculated below.  

Formula,

= change in temperature  x specific heat capacity for solid ethanol x 40

=> 0.5 x 16x 40 = 320J

Therefore, the 320J of heat is released when 40.0g of ethanol cools.
