Answer:
4 mol of KOH would produce 116.6 g of Mg(OH)₂
Explanation:
According to the following balanced equation:
- MgCl₂+ 2 KOH -----> Mg(OH)₂ + 2 KCL
One can note that 2 mol of KOH react with MgCl₂ to produce 1 mol of Mg(OH)₂.
using cross multiplication
2 mol of KOH → 1 mol of Mg(OH)₂.
4 mol of KOH → ?? mol of Mg(OH)₂.
no of moles of Mg(OH)₂ = (1 mol* 4 mol) / 2 mol =2 mol
Now we can convert moles of Mg(OH)₂ to grams using the formula
mass of Mg(OH)₂= (no. of moles * molar mass) = (2 mol * 58.3g/mol) = 116.6 g
- So, 4 mol of KOH would produce 116.6 g of Mg(OH)₂.
Answer:
All molecules of a compound have the same properties
Explanation:
- Molecules are particles of elements or compounds that are made of more than one atoms.
- Molecules of an element are made up of similar atoms. For example, Oxygen molecule, O₂, has two oxygen atoms and chlorine molecule, Cl₂, has two chlorine atoms.
- Molecules of a compound are made up of different types of atoms, for example, a water molecule, H₂O is made up of two hydrogen atoms and one oxygen atom.
- Molecules of a compound have similar properties that are similar to that of the compound. The properties of a molecule of a compound are different from those of an individual atom.
Answer:
None
Explanation:
There are two S=O. bonds and two S-O bonds in sulfate ion lewis structure. Sulfur atom is the center atom and four oxygen atoms are located around sulfur atom. There are no lone pairs in the last shell of sulfur atom.
