Answer:
They test it using the scientific method.
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
Answer:
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
Explanation:
^^^
1. So 27.3 g Fe is 0.4911 mol (27.3 / 55.58). 45.8 g O is 2.862 mol. Because of the stoichiometry, 3/4 as much oxygen as iron gets consumed. For the 0.4911 mol Fe consumed, 0.3683 mol O is consumed. 2.862-0.3863 = 2.4757 mol, or 39.6 g O is left.
2. Hydrogen is the limiting reactant for these quantities. 2/3 as much ammonia is produced as hydrogen is consumed, so for 5.0 mol H2, that's 3.33 mol NH3.
Make sense?
