The mass of a chemical substance is known as the atomic number or atomic mass
Answer:
1. Lactose with C. β-D-galactopyranosyl (1-4) β-D-glucopyranose
2. Maltose with B. α-D-glucopyranosyl (1-4) α-D-glucopyranose
3. Sucrose with A. α-D-glucopyranosyl(1-2) β-D-fructofuranoside
4. Cellobiose with D. β-D-glucopyranosyl(1-4) β-D-glucopyranose
Explanation:
Lactose is made of β-D-glucose and β-D-galactose linked via 1→4 glycosidic linkage
Maltose is made of two α-D-glucose molecule linked via 1→4 glycosidic linkage
Sucrose is made of α-D-glucose and β-D-fructose linked via 1→2 glycosidic linkage
Cellobiose is made of two molecule of β-D-glucose linked via 1→4 glycosidic linkage
From what is given, double replacement is what it is
The balanced equation for the above reaction is as follows;
2Ca + O₂ ---> 2CaO
stoichiometry of Ca to O₂ is 2:1
we first need to find the limiting reactant
number of Ca moles - 6.84 mol
number of O₂ moles - 4.00 mol
if Ca is the limiting reactant
if 2 mol of Ca reacts with 1 mol of O₂
then 6.84 mol of Ca reacts with - 6.84 / 2 = 3.42 mol of O₂
this means that Ca is the limiting reactant and O₂ is in excess
therefore amount of CaO produced depends on amount of limiting reactant present
stoichiometry of Ca to CaO is 2:2
number of moles of Ca reacted = number of CaO moles formed
number of moles of CaO formed - 6.84 mol
answer is 6.84 mol
