Answer:
Iron 55 (Fe-55) is the iron isotope whose nucleus consists of 26 protons and 29 neutrons. It is a radioisotope that disintegrates by electron capture in manganese 55.

i hope this helps if not tell me
A Lewis acid is an electron-pair acceptor.
Bronsted-Lowry bases are species that can accept a proton.
Arrhenius acid gives
ions.
<h3>What is acid?</h3>
An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).
A Lewis acid is therefore any substance, such as the
ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor.
Bronsted-Lowry bases are species that can accept a proton due to a high-energy pair of electrons being present.
According to Arrhenius, the acids are the hydrogen-containing compounds which give
ions or protons on dissociation in water and bases are the hydroxide compounds which give
ions on dissociation in water.

Hello,
The answer is option A "<span>the heat from the stove".
Reason:
The answer is option A because the variable the heat from the stove is causing the ice to change into water. Its not option B because thats not in the procedures. Its not option C because it is not a variable. Its also not D because thats also not a variable.
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
The coordination number.
Explanation:
The coordination number is defined as the number of atoms surrounding an atom in a crystal lattice and indicates how tightly the atoms are packed together.
Coordination number is also known as ligancy in chemistry and it basically refers to the total or overall number of neighboring ions, atoms or molecules with respect to a central atom in a crystal lattice. The term coordination number was first defined by the notable and amiable Swiss chemist by the name, Alfred Werner in 1893.
Generally, the coordination number of an atom in a crystal lattice can have a minimum value of two (2) and a maximum value of sixteen (16). It is usually determined by the size of the ligands, central atom and the charge associated with the electronic configuration of an ion. For example, the coordination number of carbon in methane (CH4) is four (4) because an atom of carbon has four (4) atoms of hydrogen bonded to it.
A solution is a homogenous mixture meaning it has a uniform appearance throughout. (example: salt water)
heterogeneous mixture is visibly composed of different things. (example: chicken noodle soup)
