Answer: It is a Lewis acid/base reaction, and 
is the Lewis acid.
Explanation:
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
can readily accept electrons and thus act as a lewis acid which is short of electrons.
can readily lose electrons and thus act as a lewis base which has excess of electrons.
It is a Lewis acid/base reaction, and is the Lewis acid.
The correct answer is a liter.
The SI or the International System of Units illustrates seven measuring units as a fundamental set from which all the other SI units can be obtained. The SI base units and their physical quantities are the kilogram for mass, the meter for measurement of length, the ampere for electric current, the second for time, the candela for luminous intensity, the Kelvin for temperature, and the mole for the amount of substance.
Answer:
sodium carbonate decahydrate
Explanation:
Usually we would the molar mass of Na2CO3 x 10 H2O. This is where the name comes from.
Answer:
Mass = 2.12 g
Explanation:
Given data:
Volume of KMnO₄ = 255 mL (255/1000 = 0.255 L)
Molarity = 0.0525 M
Mass in gram = ?
Solution:
First of all we will calculate the number of moles.
<em>Molarity = number of moles of solute / volume in litter</em>
0.0525 M = number of moles of solute / 0.255 L
Number of moles of solute = 0.0525 M ×0.255 L
Number of moles of solute = 0.0134 mol
Mass in gram:
<em>Number of moles = mass/ molar mass</em>
Mass = moles × molar mass
Mass = 0.0134 mol × 158.04 g/mol
Mass = 2.12 g
