Answer : The formula of hexaaquamanganese(II)sulfate is ![[Mn(H_2O)_6]SO_4](https://tex.z-dn.net/?f=%5BMn%28H_2O%29_6%5DSO_4)
.
Explanation :
Rules for writing formulas of coordination complexes :
- Central metal is written first and then the ligands are written along with their prefixes.
- The anion ligands are written before the neutral ligands.
- If there are more than one anion ligands or neutral ligands then they are written in alphabetical order.
The given name of complex is, hexaaquamanganese(ii) sulfate.
In this, the central metal is manganese which is written as Mn and the ligand is water (which is a neutral ligand) is written as 
and an anion is sulfate which is written as 
.
Water is a neutral ligand and sulphate has a charge of -2. As the overall complex is neutral the metal bears a +2 charge which is represented in Roman numeral after the metal.
Therefore, the formula of hexaaquamanganese(II)sulfate is written as .
Answer:
The salt that is produces is NaBr.
Explanation:
When an acid react with base it form the salt and water. The reaction is also called neutralization reaction because both neutralize each other.
In neutralization reaction equal amount of acid and base react to neutralize each other and equal amount of water and salt are formed. When pH does not reach to 7 its means there is less amount of one of reactant which is not fully neutralize.
Neutralization reactions are also used as first aid. For example when someone is dealing with HCl for cleaning purpose of toilet and get touched. It is advised to neutralize it with soap, milk or egg white.
Example:
Hydrobromic acid when react with the sodium hydroxide, a salt sodium bromide and water are formed.
Chemical equation:
HBr + NaOH → NaBr + H₂O
Properties of Sodium Bromide:
- It is present in the form of colorless crystals.
- It is also present in powder form.
- It is very toxic.
- It is soluble in water.
- It is bitter in taste and also odorless.
Answer:
Al
Explanation:
Aluminum (Al) is in the same group as Boron (B) so it should have three electrons or dots around it.
Hope that helps.
Answer: Sodium Chloride because its still a liquid at the 773 temperature
Explanation: hope this helps :)
Combinations of different metals form alloys. An alloy composed by mercury and other metal (or metals) forms amalgam. When a true alloy is formed, the component metals are mixed together at a temperature which is greater than the melting point of all of them.Apr 7, 2017
