Surface currents are driven by Wind.
Wind blows in patterns due to the Coriolis effect
What affects surface currents ?Ocean surface currents are typically created by wind. On the northern and southern hemispheres, the revolution occurs in a clockwise and an anticlockwise direction, respectively. The Coriolis effect has a significant impact on the wind's characteristics and pattern.
The climate is influenced by wind patterns, and the Coriolis effect, a byproduct of the rotation of the earth, has an impact on the curvature of the wind mass. The equator's wind rises in this process from the northeast of the Northern Hemisphere.

Understanding the Electronic Structure Evolution of Epitaxial LaNi1–xFexO3 Thin Films for Water Oxidation
Rare earth nickelates including LaNiO3 are promising catalysts for water electrolysis to produce oxygen gas. Recent studies report that Fe substitution for Ni can significantly enhance the oxygen evolution reaction (OER) activity of LaNiO3. However, the role of Fe in increasing the activity remains ambiguous, with potential origins that are both structural and electronic in nature. On the basis of a series of epitaxial LaNi1–xFexO3 thin films synthesized by molecular beam epitaxy, we report that Fe substitution tunes the Ni oxidation state in LaNi1–xFexO3 and a volcano-like OER trend is observed, with x = 0.375 being the most active. Spectroscopy and ab initio modeling reveal that high-valent Fe3+δ cationic species strongly increase the transition-metal (TM) 3d bandwidth via Ni–O–Fe bridges and enhance TM 3d–O 2p hybridization, boosting the OER activity. These studies deepen our understanding of structural and electronic contributions that give rise to enhanced OER activity in perovskite oxides. true or false

Mathematically this equation is correct, but in terms of the meaning that people derive from it is totally wrong.
E = mc²
Some statements are mass is a condensed form of energy or energy is available in every mass.
On the original paper that Einstein published that he stated the equation as :
m = E / c²
This implies that the more energy the object has, it’s mass keeps on increasing.

Explanation:
It takes trial and error to balance a chemical equation, but after fidgeting with it for a while the lowest, whole-number coefficients are as follows:
4NH3(g)+5O2(g)⇒4NO(g)+6H2O(g)
We can check this by simply counting the number of molecules on either side of the equation, and adjusting as needed. It's important to remember that we can only ever change the coefficients to balance, never the subscripts.
Once counting the coefficients, we reach a sum of 19.

What is the oxidized ?
Oxidation is a chemical reaction that involves the transfer of electrons from one molecule or atom to another. In other words, it is a process in which an element or compound loses one or more electrons. Oxidation occurs when an atom or molecule gains oxygen or loses a hydrogen atom. Oxidation can also occur when a substance is exposed to light, heat, or other forms of energy. Oxidation can lead to the production of free radicals, which can cause cell and tissue damage, resulting in various diseases, such as cancer and heart disease.

Sulfur: Oxidized from 0 to +4
Oxygen: Oxidized from -2 to 0
Reduction:
Hydrogen: Reduced from +1 to 0
Explanation: In this reaction, sulfur is oxidized from 0 to +4 as it gains 4 electrons. Oxygen is oxidized from -2 to 0 as it gains 2 electrons. Hydrogen is reduced from +1 to 0 as it loses 1 electron.

When NAD+ obtains a hydrogen atom, the molecule is reduced because it loses an electron as a result of the gain.
If a molecule obtains hydrogen, it is said to be reduced; if it loses hydrogen, it is said to be oxidized. During metabolism, the coenzyme NAD+ receives and releases hydrogen. The coenzyme depletes after absorbing hydrogen, aiding in the transmission of electrons into the electron transport chain, which is necessary to carry out oxidative phosphorylation, the process that produces ATP. As a result, the NADH is once more oxidised to NAD+ by performing this.. NAD+ changes into NADH as it absorbs electrons from food molecules.
