Potassium iodide is an ionic compound.
Describe what happens, in terms of electron loss and gain, when a potassium atom reacts
with an iodine atom.
Answers
Answer:
In this reaction, potassium atoms lose electrons to form positively-charged potassium ions (oxidation) and iodine atoms gain electrons to form negatively-charged iodide ions (reduction).
Explanation:
pls mark as brainliest
In this process, iodine atoms get electrons to produce negatively charged iodide ions, whereas potassium atoms lose electrons to form positively charged potassium ions. Oxidation and reduction takes place.
What is oxidation ?Redox reactions include a change in the oxidation state of the substrate. Similar to how reduction is the acquisition of electrons while oxidation is the loss of electrons or an increase in the oxidation state.
An oxidation process takes place when oxygen interacts with a substance or an element. Another way to think of oxidation is as the process of removing hydrogen from the species of reactants. Molecule, atom, or ion oxidation is the process of losing electrons.
Because they generate new functional groups in molecules or alter existing functional groups, oxidation processes are crucial in the synthesis of organic substances.
Thus, the iodine atom also experiences a change. The iodide atom gets one electron during the reaction with potassium, leaving it with eight electrons at its outer energy level.

Which phrase describes transmutation?(1 point)
the conversion of an atom of one element into a different element through nuclear changes
the conversion of energy to matter through chemical changes
the conversion of protons to neutrons through nuclear changes
the conversion of one substance to another through chemical changes
Help plss quick
thx
Answers
The phrase that describes transmutation is ; ( A ) The conversion of an atom of one element into different element through nuclear changes.
Transmutation is simply the change of an element to another element, transmutation occurs at the nucleus of the atom of an element and this process is initiated through nuclear reaction ( radioactive decay ).
Therefore the conversion of an atom of one element into different element through nuclear changes summarizes the term "transmutation".
Hence we can conclude that the phrase that describes transmutation is the conversion of an atom of one element into different element through nuclear changes.

3. Give 1 reason why this chemical reaction/equation follows OR does not follow the law of conservation of matter?
Answers
1. No, it doesn't.
2. 4 Hydrogen atoms are on the reactants side and 2 hydrogen atoms on products side.
3. Because the mass of reactants is not equal to the mass of the products thus it doesn't follow the law of conservation of matter.
But on balancing the eqn,
CH4 + 2O2 > CO2 + 2H2O
The above eqn will follow the law of conservation of matter because the mass of reactants is equal to the mass of products.
