We are required to explain the meaning of volume and mention the instrument used to measure liquid volume.
Since, volume comprises of length, width and height, then the formula used to calculate the volume of a solid object is length multiplied by width multiplied by height.
Therefore,
Volume of a solid object = Length × Width × Height

Answer:
Volume is the amount of space that a substance occupies. A graduated cylinder is used to measure liquid volume. The formula used to calculate the volume of a solid object is = L x W x H
Explanation:
B. electrons than protons
C. neutrons than protons
A positive ion, also known as a cation, has more protons than electrons as a result of losing electrons. For example, a sodium atom becomes a +1 sodium ion when it loses an electron. The number of neutrons does not affect the charge of ions.
A positive ion, also known as a cation, is formed when an atom loses one or more electrons. This causes the atom to have more protons than electrons, thereby gaining a positive charge. So, the correct answer to your question is A. Protons than electrons.
For instance, when a sodium atom (which has 11 protons and 11 electrons) loses an electron, it becomes a sodium ion with a +1 charge, having 11 protons and only 10 electrons.
Neutrons are particles present in the nucleus of an atom that do not carry any charge. Hence, the number of neutrons doesn’t affect the charge of ions.

A positive ion, or a cation, has more protons than electrons because it forms by losing electrons. Therefore, it has a net positive charge. The number of protons and neutrons doesn't change during this process.
A positive ion, also known as a cation, is formed when an atom loses electrons. The loss of electrons results in the atom having more protons than electrons, and subsequently more positive charge than negative, hence the name positive ion. Therefore, the correct answer to your question is A. protons than electrons. However, it’s important to note that the number of protons and neutrons in an atom does not change during chemical reactions or during the formation of ions.

FE stands for iron in the Periodic Table of Elements.
Iron is a chemical element with the atomic number 26 and the symbol Fe, derived from the Latin word "ferrum." It is a transition metal and belongs to Group 8 and Period 4 of the periodic table.
Iron is well-known for its distinctive qualities, including its tremendous strength, silvery-gray colour, and magnetic tendency. It is an essential component in the creation of steel and is necessary for many biological activities, including the transfer of oxygen in the blood. Iron compounds are frequently employed in both industrial settings and daily life.

Answer: you cannot change the subscripts in a formula in order to balance a chemical equation because the subscripts indicate the number of each kind of atom in the formula,
Each compound has an invaraible chemical formula which tells how many atoms of every kind constitute the compound.
Varyng the subscripts is a modification of the chemical formula, meaning that you end up with a different compound.
On the other hand, by varying the coefficients, you only modifiy the number of unit formulas (number of molecules of the compound) that intervene in the reaction, which is what you want to indicate by balanceing reactants and products.
Answer:odium
Explanation:
Among the metals Sodium, Rubidium, Aluminum, and Indium, Rubidium is the most reactive due to its position in the alkali metals group in the periodic table. The reactivity of metals increases as you go down in any group.
The question asked was: 'Out of Sodium, Rubidium, Aluminum, and Indium, which is the most reactive metal?' In the periodic table of elements, reactivity of metals increases as we move down in any group. Sodium and Rubidium are alkali metals present in Group 1. Out of these two elements, Rubidium is further down in the group and is thus more reactive compared to Sodium. However, Aluminum and Indium belong to different groups and are relatively less reactive when compared to alkali metals.
Passivation, or the formation of nonreactive film of oxide on metals such as Aluminum, makes them less reactive compared to alkali metals, which readily react with water and oxygen. In conclusion, among Sodium, Rubidium, Aluminum, and Indium, Rubidium is the most reactive metal.
