Answer:
2 Silver Ions
1 Oxygen Ion
Explanation:
Edg2021
The chemical symbol for silver oxide is not Ag₂0. The correct chemical formula for silver oxide is Ag₂O.
Silver oxide (Ag₂O) is an ionic compound composed of silver ions (Ag⁺) and oxide ions (O₂⁻). It is commonly used in button batteries as a cathode material. In this compound, two silver ions combine with one oxide ion to form a stable structure.
The chemical formula Ag₂O indicates that there are two silver ions (Ag⁺) and one oxide ion (O₂⁻) in each formula unit of silver oxide. The subscript 2 after Ag indicates that there are two Ag⁺ ions present, while the absence of a subscript after O indicates that there is one O₂⁻ ion.
Hence, the chemical formulae are discussed above.

Suppose 10 atoms of carbon (C) react with 20 atoms of oxygen (O). According to the Law of Conservation of Matter, how many atoms will there be in the product of this reaction?(1 point)
A) 20
B) 15
C) 10
D) 30
Answer:
D 30
Explanation:
whenever there is a reaction, the amount of atoms don't change, because matter can't be created or destroyed. Add the carbon and oxygen atoms together
According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
LAW OF CONSERVATION OF MATTER:
The law of conservation of matter states that matter can neither be created nor produced in a chemical reaction. This further means that the amount of matter in the reactant of a reaction must equate that of the products. Hence, if 10 atoms of carbon (C) react with 20 atoms of oxygen (O), there will be 10 + 20 = 30 atoms of product in this reaction. Therefore, According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.Learn more: https://brainly.com/question/24996173?referrer=searchResults

A Potassium isotope contains 19 protons, 19 electrons and 21 neutrons. What is its mass number? 40
Answer:
17
Explanation:
you add 19+19 the subtract 21. I think
A potassium isotope contains 19 protons, 19 electrons, and 21 neutrons, so the mass number is 40 as the mass number of the atom is the sum of the protons and the neutrons, the mass number is 40.
What is the significance of the mass number in the atom?The mass number is significant as it is the sum of the number of protons and neutrons present in nucleus of an atom, which determines the atomic weight of an element and also determines its chemical properties and its position on the periodic table. Isotopes of an element have the same atomic number but a different mass number, so they have different properties than the original element.
Hence, a potassium isotope contains 19 protons, 19 electrons, and 21 neutrons, so the mass number is 40 as the mass number of the atom is the sum of the protons and the neutrons, the mass number is 40.

It has a low melting point.
It can be flattened and bent.
It cannot be shaped into wires.
It does not conduct electricity.
Answer:
B: it can be flattened and bent
Explanation:
Metals are malleable and can be flattened. Metals are ductile and can be deformed and bent.
Metals are bonded together by metallic bonds.
Hence a substance that is composed of atoms that are held together by metallic bonds can be flattened and bent.
The property of a substance that is composed of atoms that are held together by metallic bonds is it can be flattened and bent
What is metallic bond ?Metals are malleable, ductile substance can be deformed when it is bent down, theses are bonded by metallic bond and can be flattened.
The metallic bond is a force of attraction which is responsible for holding the atoms together, releases electrons to achieve the configuration of a noble gas.
in this type of bonding all the atoms lose their electrons from their outermost layers that move more or less freely between them, forming an electronic cloud
The metallic bond is the exceptional bond where the electrons are not present exclusively between a pair of atoms, but these are relocated among millions of them called as "sea of electrons" by cohesive bond.
