The most common method to get an idea about the pH of solution is to use an acid base indicator. An indicator is a large organic molecule that works somewhat like a " color dye". Whereas most dyes do not change color with the amount of acid or base present, there are many molecules, known as acid - base indicators<span> , which do respond to a change in the hydrogen ion concentration. Most of the indicators are themselves weak acids.</span>
The properties of matter can best be explained using a model in which all materials are composed of tiny particles (atoms, molecules and ions). There is empty space between particles and particles are constantly moving (their speed is changed by temperature).
Answer:
The answer is "Comet".
Explanation:
The comets were interstellar frozen gas of snowballs, stone, and debris orbiting the sun, which are also the size of average towns while frozen. As even the orbit of the comet passes near the sun, it warms up and spreads dust and gas into a big floating head greater than most stars.
- It is very important because they are primitive items left out from the galaxy creation.
- They were one of the first solid materials throughout the solar nebula, its collapsing interstellar-like cloud of dust and gas, which established the heat and planets.
Answer:
Carbon tetrafluoride
Explanation:
There is one carbon atom and four fluorine that's why its name is carbon tetrafluoride.
It is the covalent compound of carbon and fluorine.
One carbon atom share its four valance electrons with four atom of fluorine.
There are seven valance electrons in one atom of fluorine and it needed only one electron to complete the octet.
That's why one carbon atom with four valance electrons combine with four atoms of fluorine.
It is less soluble in water.
it is readily soluble in ether and alcohol.
Its molecular weight is 88.004 g/mol.
Its molecular formula is CF₄.
It form covalent bond with high strength.
