Answer:
In the parallel plate capacitor,
q = e0EA, q is the charge on the plate, E is electric field intensity, A is the area of each plate, e0 = 8.854 x 10^-12F/m.
The charge density is q/A(charge per unit area)
q/A = e0 x E, from the equation above.
Therefore, q/A = 1.40 x 10^4V/m x 8.854 x 10^-12F/m
q/A = 12.3956 x 10^-8 = 1.23956 x 10^-7C/m2
Explanation:
A parallel plate capacitor consist of two plates facing eachother with separation d in between them. One of the plate is positively charged and the other is negatively charged. There is a dielectric material in between the plates. The charges on the plate is given as: q = e0EA
The balance chemical equation is follow,
2 I⁻ + SO₄²⁻ + 4 H⁺ → I₂ + SO₂ + 2 H₂O
According to this reaction, 2 moles of I⁻ reacts with 1 mole of SO₄²⁻ to produce 1 mole of I₂ and 1 mole of SO₂.
Result:
So with the formation of 1 mole of I₂, 1 mole of SO₂ is produced.
<em><u>Ionic bonds</u></em> <span>are the type of bonds where there is </span><u>transfer</u><span><u> </u>of electrons from one atom to another. The electrons are removed and from one atom and attached to another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.</span>

here is your answer buddy
Ice-albedo feedback is a strong positive feedback in the climate system. Warmer temperatures melt persistent ice masses in high elevations and upper latitudes. Ice reflects some of the solar energy back to space because it is highly reflective.

A single replacement reaction
<h3>Further explanation
</h3>
There are two types of chemical reactions that may occur.
namely single-replacement reactions and double-replacement reactions.
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
Not all of these reactions can occur. We can use the activity series, which is a list of elements that can replace other elements below / to the right of them in a single replacement reaction.
This series is better known as the Volta series, where the metal element with a more negative electrode potential is on the left, while the element with a more positive electrode potential on the right.
The more left the position of a metal in the series, the more reactive metal (easy to release electrons, the stronger as the reduction agent)
The metal activity series is expressed in voltaic series
<em>Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-</em><em>Fe</em><em>-Cd-Co-Ni-Sn-Pb- (H) -</em><em>Cu</em><em>-Hg-Ag-Pt-Au </em>
Fe(more active element) takes the place of Cu(less reactive element) in the CuSO4 compound
