A law in Chemistry ; the elements when arranged in the order of thier atomic numbers show periodic varation of the autmoic structure and of their most properties - Also know as the Mendeleev's Law
Answer:
look at the picture
Explanation:
There are total 118 elements, out of which 92 are found in nature while the remaining have been artificially prepared. These elements are divided into metals, non-metals and metalloids depending upon their properties.
Answer:
A balanced chemical equation follows law of conservation of mass. This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This means that total mass on the reactant side is equal to the total mass on the product side.
Answer:
Molar mass of monoprotic acid is 1145g/mol.
Explanation:
The reaction of a monoprotic acid (HX) with NaOH is:
HX + NaOH → H₂O + NaX
That means 1 mole of acid reacts with 1 mole of NaOH
If the neutralization of the acid spent 20.27mL of a 0.1578 M NaOH solution. Moles of NaOH are:
0.02027L × (0.1578mol / L) = <em>3.199x10⁻³ moles</em> NaOH ≡ moles HX.
As mass of the sample is 3.664g, molar mass of the acid is:
3.664g / 3.199x10⁻³ moles =<em> 1145g/mol</em>
I believe that is condensation
