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
Explanation:
molarity = no. of moles of solute/solution in litres
5.1M=no. of moles of solute/7.3
5.1×7.3=no. of moles of solute
37.2 mol =no. of moles
Answer:
Notice that the photosphere actually has a temperature quite close, or even a bit colder, than the Earth's core! However, outside the photosphere there is the Sun's corona, which can reach temperatures as high as 17,000,000 K; this is hotter than the center of the Sun, and is the hottest place in the solar system!
Enthalpy change during the dissolution process = m c ΔT,
here, m = total mass = 475 + 125 = 600 g
c = <span>specific heat of water = 4.18 J/g °C
</span>ΔT = 7.8 - 24 = -16.2 oc (negative sign indicates that temp. has decreases)
<span>
Therefore, </span>Enthalpy change during the dissolution = 600 x 4.18 X (-16.2)
= -40630 kJ
(Negative sign indicates that process is endothermic in nature i.e. heat is taken by the system)
Thus, <span>enthalpy of dissolving of the ammonium nitrate is -40630 J/g</span>
Answer:
The difference between liquid nitrogen and nitrogen gas is liquid nitrogen gas is man made or caused by humans but, nitrogen gas takes place naturally in the earths atmosphere.
