Answer:
The ionic bond occurs between two different atoms (metal and nonmetal), while the covalent bond occurs between two equal atoms (nonmetals),
Another difference between these is that the covalent bond is an electron compartment, while in the ionic bond there is an electron transfer.
Metal bonding occurs when metals are combined with each other. Metal atoms need to give up electrons to reach the configuration of a noble gas. In this case, the metals lose the valence electrons and an electron cloud forms between the positive nuclei.
The answer to this question is:
The mobility of electrons.

An action or the movement of the planet on its tilted axis that involves a whole turn or circular motion from its initial point and back to it is called a rotation.
The time it takes for a planet to make a complete rotation is the length of its day.
Rotation of the planet is the circular turn or the motion of the planets on its axis from one point and back to it.
The rate of the rotation of the different planets varies based on their sizes and distances from the sun. It is also called the length of the day as the rotation defines the circular motion it completes in a defined day.
Therefore, option A is correct.

pH scale ranges from 0 (highly acidic) – 14 (highly alkaline). The pH of a neutral solution is 7. Acidic solution is represented by a value less than 7 on the pH scale.
pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions.
Scientists use something called the pH scale to measure how acidic or basic a liquid is.
Although there may be many types of ions in a solution, pH focuses on concentrations of hydrogen ions () and hydroxide ions ().
The scale measures values from 0 all the way up to 14. Distilled water is 7 (right in the middle).

Reds are strong acids
yellows are weak acids
green is neutral
blue is kinda basic
and purple is super basic
keep in mind, this is just the litmus paper scale
decomposition
single displacement
double displacement
Answer:
decomposition
Explanation:
becoz it is a single compound and it under goes to give two give two or more products
