Answer:
[OH-] = 10^-1.5 = 0.0316 M
Explanation:
Answer:
22g
Explanation:
Given parameters:
Mass of element A = 18g
Mass of element B = 4g
Unknown:
Mass of compound formed = ?
Solution:
The reaction equation is given as;
A + B → AB
According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".
Simply mas is conserved and the mass of the reactants is the same as the mass of the product that forms.
Mass of reactants = mass of A + mass of B = 18g + 4g = 22g
So;
Mass of product AB = 22g

The Physical properties of Iron are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.
Explanation:
Color Silver-gray metal
Malleability Capable of being shaped or bent
Ductility Easily pulled or stretched into a thin wire
Luster Has a shine or glow
Conductivity Good transmission of heat or electricity
Allotropy It occurs in two or more crystalline forms in the same physical state
Tensile It can be stretched without breaking
Ferromagnetic Easily magnetized
