Conservation, because you are conserving natural resources(water) and reusing aluminum cans which help the environment. Hope this helps!

1. We have new knowledge of how charge can be transferred from one object to another

NeX [460]

Charge can be transferred from one object to another in three way conduction, polarization, and friction

Whenever electrons are transferred between objects, neutral matter becomes charged and three ways this can occur are referred to as conduction, polarization, and friction conduction means when there is direct contact between materials that differ in their ability to give up or accept electrons when two different materials are rubbed together, there is a transfer of electrons from one material to the other material and this causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer)

Here given object is water + balloon; balloon + wall; tape then you rub a balloon against your clothes and it sticks to the wall, you are adding a surplus of electrons (negative charges) to the surface of the balloon the wall is now more positively charged than the balloon and we tested the conductivity of deionized water positively charged

Lithium and fluorine undergo ionic bonding. Using the noble gas electron configurations for each (below), please explain the pro

Slav-nsk [51]

Answer:

Lithium loses one electron to fluorine and forms ionic bond, having formula $LiF$ .

Explanation:

Lithium is the element of the group 1 and period 2 which means that the valence electronic configuration is $[He]2s^1$ .

Fluorine is the element of the group 17 and period 2 which means that the valence electronic configuration is $[He]2s^22p^5$ .

<u>Thus, lithium loses 1 electron and become positively charged. Fluorine on the other hand accepts this electron and become negatively charged.</u> This is done in order that the octet of the atoms are complete. <u>These both ions then form ionic bond as their will be electrostatic interaction between the two oppositely charged ions.</u>

Thus, the formula of calcium chloride is $LiF$ .

g The reaction C(s) + CO2(g) → 2CO(g) is spontaneous only at temperatures in excess of 1100 K. We can conclude that a. ΔG° is ne

mel-nik [20]

Answer:

c. ΔH° is positive and ΔS° is positive.

Explanation:

Hello,

In this case, as the Gibbs free energy for a reaction is defined in terms of the change in the enthalpy and entropy as shown below:

$\Delta G=\Delta H-T\Delta S$

Thus, as the reaction becomes spontaneous (ΔG°<0) at temperatures above 1100K (high temperatures), it necessary that c. ΔH° is positive and ΔS° is positive as the entropy will drive the spontaneousness as it becomes smaller than TΔS°.

Best regards.
