Answer:
C. gold atoms
Explanation:
Metallic bonds are found between atoms of metals. Since gold is the only metal given here, it is the solution to the problem.
Metallic bonds join atoms of metals and alloys together.
The formation of this type of bond is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.
The metallic bond is actually an attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all atoms losing their outermost shell electrons.
0.5 mg/mL would be expressed as 500 ug/uL
Answer:
There are 18572.9 arcminutes in 86% of a circle.
Explanation:
The degrees in 86% of a circle is:
Now, we need to find the number of arcminutes in 309.6°:
Therefore, there are 18572.9 arcminutes in 86% of a circle.
I hope it helps you!
The hydroxide ions keep decreasing and the hydrogen ions increase, pH decreases.
<h3>What is hydroxide?</h3>
Hydroxide is a diatomic anion with synthetic recipe OH⁻. It comprises of an oxygen and hydrogen particle kept intact by a solitary covalent bond, and conveys a negative electric charge. It is a significant yet generally minor constituent of water. It capabilities as a base, a ligand, a nucleophile, and an impetus. Hydroxide is a diatomic anion with chemical formula OH −. It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. Hydroxide ions can act as a catalyst in different types of reactions. Hydroxide ions can function as base, ligand, nucleophile or a catalyst.

<span>Solar energy arrives and is converted into chemical energy by plants which is eaten by animals and converted again and the animal is either eaten by another animal or dies and is broken down by decomposers and the energy is converted back into basic elements for plants to feed off of with the help of solar energy hence the cycle starts again
sorry this is all i know i hope it helps</span>
