Answer:
HCI
Explanation:
The solution with the lowest pH is HCI with a pH value of 1. It is understood that it is more acidic because it is a strong acid.
The answer is 20 because in an atom no of protons equal no of electrons
Answer:
The answer to your question is: Phosphorous acid
Explanation:
Phosphorous can form 2 main acids
H₃PO₃ is called phosphorous acid
H₃PO₄ is called phosphoric acid
Answer:
Fe(NO3)3 is ionic.
Explanation:
Ionic bond:
Ionic bond is formed when oppositely charged ions attract each others i.e negative and positive ions.
We know that a neutral atom consist of equal number of proton and electron, cancel the charge of each other that is equal in magnitude and make the atom neutral or we can say that net charge is zero.
But when the atom lose or gain the electron, imbalance of neutron electron occur so charge will not remain zero and atom is no more to be said neutral.
In given compound Fe(NO3)3 the Fe is act as cation while nitrate is act as anion.
3Fe+ (Cation)
3NO3 ∧ -1 (anion)
3Fe∧+1 + 3NO3 ∧ -1 → Fe(NO3)3
Another example of ionic compound:
Now consider the sodium chloride which is an ionic compound. It is formed by the complete transfer of electron from sodium to chlorine atom and form ionic bond. In this ionic compound sodium carry positive charge and chlorine carry negative charge there is attraction between these oppositely charged atoms.
Na+ (cation)
Cl- (anion)
NaCl
Covalent bond:
Covalent bond involve the sharing of electrons between the atoms. It is also called molecular bond. These electron pairs are called bonding electrons are shared pair of electrons.
Answer:
Calcium monohydride is a molecule composed of calcium and hydrogen with formula CaH. It can be found in stars as a gas formed when calcium atoms are present with hydrogen atoms.Calcium carbonate is a chemical compound with the formula CaCO3 formed by three main elements: carbon, oxygen and calcium.
