<u>Answer:</u> 3 neutrons are produced in the above nuclear reaction.
<u>Explanation:</u>
In a nuclear reaction, the total mass and total atomic number remains the same.
The nuclear reaction for the fission of Americium-244 isotope follows:

<u>To calculate Y:</u>
Total mass on reactant side = total mass on product side

Hence, 3 neutrons are produced in the above nuclear reaction.
KI or "Potassium Iodide" is a combination between a metal (potassium) and a nonmetal (iodine). In order to bond, iodine has to accept an electron from potassium, making them both ions. This combination between a metal cation and a nonmetal anion is an ionic bond.
Polarity is a term used in electricity, magnetism, and electronic signaling. Suppose there is a constant voltage , also called an electric potential or electromotive force (EMF), between two objects or points. In such a situation, one of the objects or points (poles) has more electrons than the other.
<h3>What causes electrical polarity?</h3>
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it's usually an easy repair.
<h3>Why is electrical polarity important?</h3>
When working with electrical circuits, we often refer to the polarity between different points in the circuit. Understanding polarity is important for connecting the leads of polarity-dependent devices such as some meters and motors. Polarity is also important for determining the direction of current flow.

The balanced equation for the generation of sugar from
sunlight water and CO₂ is
6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
carbon dioxide + water → sugar + oxygen
<span>The process of photosynthesis occurs
when the chlorophyll present in the leaves of plants absorb sunlight to make
food in the presence of carbon dioxide (enters through the stomata of leaves)
and water (absorbed from the roots). As a result of this reaction sugar and
oxygen is formed. After that sugar is converted in to starch and oxygen is released
into air.</span>
