Explanation:</h3>
What is a compound?
- A compound is a substance that is made up of atoms from different elements.
- The formula of a compound shows the elements making up the compound.
- Additionally, the formula of compound shows the number atoms of each element making up the compound.
In this case;
We are given the Formula KBr
- This is the formula of the compound potassium bromide.
- From the formula, we can tell that the compound is made up of potassium and bromine atoms.
- The formula also shows the number of atoms of each element, that is, 1 potassium atom and 1 bromide atom.
Im guessing here but i think it's true
The melting point of a particular compound is fixed and it is an important identification of an unknown compound. The practice to determine the melting point of an unknown material In different ratio with a known material is important to get the exact melting point of the unknown material. In different ratio the melting point of the unknown material will be fixed as the melting point of a pure material doesn't depend on the ratio in which they are mixed with other material. To get the exact melting point it is always good to get the melting point twice in different ratio.
Answer:
layers of rock get folded
Answer:
Electron pair acceptor- Lewis acid
Proton donor- Bronsted-Lowry acid
Provides H+ in water- Arrhenius acid
Explanation:
A Lewis acid is any specie that accepts a pair of electrons such as Al^3+, Fe^2+ etc.
A Brownstead Lowry acid is any specie that donates a proton, e.g H3O^+
An Arrhenius acid is a specie that provides in solution, that is, any specie that provides H^+ in solution.
