Explanation:
(a) The molecular equations shows the equation in which all the species of the reactants and the products are in molecules and the net charge is zero.
The complete ionic equations shows the equation in which all the species of the reactants and the products are in dissociated form and are represented as ions.
The net ionic equations shows the equation in which all the species of the reactants and the products are in dissociated form and do not show the spectator ions which are same in the reactants and the products.
(b) If there is no spectator ions in the reaction, then the complete and the net ionic equations would be identical.
Answer:
8.38×10raise to power 23
Explanation:
mass of sugar=density ×volume
=. 1.59g/ml×25ml=39.75
no. of miles= given mass/ molar mass
= 39.75/342.3g / mole
1 mole of sugar =C12 H22 O11
contains
12× 6.023 × 10 ∆23=72.28× 10∆ 23 ×6.023×10²³
= 8.38× 10²³
The empirical formula of the substance would be 
<h3>Empirical formula calculation</h3>
The constituents of the compound are as follows:
N = 54/201.6 = 26.78% = 26.78/14 = 1.91 moles
H = 15/201.6 = 7.44% = 7.44/1 = 7.44 moles
Cl = 132.6/201.6 = 65.48% = 65.48/35.5 = 1.84 moles
Divide the number of moles by the smallest"
N = 1.91/1.84 = 1
H = 7.44/1.84 = 4
Cl = 1.84/1.84 = 1
Thus, the empirical formula is
