Answer:
1. Starch
2. Cellulose (vegetable fibers)
3. Glycogen
Explanation:
Carbohydrates: They are bio-organic molecules synthesized by plants. these molecules are mainly made up of carbon, hydrogen and oxygen and consists of 1 to many sugar unit.
Sugar unit: C₆H₁₂O₆
on the basis of their unit and structural complexity there are three types of carbohydrates
1. Sugars:
These carbohydrates are composed of 1 to 2 units of glucose and these sugars have simple in structure and digestible and easily absorbed in blood.
2. Oligosaccharides:
These carbohydrates are composed of 3 to 9 units of glucose and these are the simplest polysaccharides are simple in structure and easily can be hydrolysed and digestible upon hydrolyzation easily absorbed in blood.
3. Polysaccarides:
These carbohydrates are composed of more than 9 units of glucose and these are complex in structures. These polysaccharides are of long chain and high wight and some of these can be hydrolysed and digestible upon hydrolyzation, but some can not be broken into simple sugar by hydrolyzation and can not be digested.
Now we have to explain about Complex Carbohydrates
1. Plant-derived digestible carbohydrate:
Plant synthesize carbohydrates and they stored in the form of oligosaccharides and polysaccarides that are of long chain and complex structure. Among these complex carbohydrates starch are digestible.
2. Plant-derived indigestible carbohydrate
Plant synthesize carbohydrates and they stored in the form of oligosaccharides and polysaccarides that are of long chain and complex structure. Among these complex carbohydrates cellulose (vegetable fibers) are insoluble and can not be digestive.
3. Animal-derived carbohydrate
Animals store the simple sugar in the form of glycogen. These glycogen are long chains of glucose and can be re-used by the body in need of energy
Answer:
808
Step-by-step explanation:
One serving of Original Pringles = 28 g = 150 Cal
Pringles ⟶ Cal 50 g × (150 Cal/28 g) = 268 Cal
Cal ⟶ J 268 Cal × (4184 J/1 Cal) = 1.121 × 10⁶ J
J ⟶ N·m 1.121 × 10⁶ J × (1 N·m/1 J) = 1.121 × 10⁶ N·m
N·m ⟶ m 1.126 × 10⁶ N·m/455N = 2460 m
m ⟶ km 2460 m × (1 km/1000 m) = 2.46 km
km ⟶ mi 2.46 km × (0.6214 mi/1 km) = 1.53 mi
mi ⟶ ft 1.53 mi ×(5280 ft/1 mi) = 8080 ft
ft ⟶ flights 8080 ft × (1 flight/10 ft) = 808 flights
The student would have to climb 808 flights of stairs to burn off the energy from 50 g of Pringles [that's equivalent to climbing the stairs in the Salesforce Tower (1070 ft) in San Francisco about 7½ times].
the mass in grams of 1.00 x 10^23 molecules of N2 is 4.648 g
<u><em>calculation</em></u>
Step 1: use the Avogadro's constant to determine the moles of N2
According to Avogadro's law 1 mole = 6.02 x 10 ^23 molecules
? moles = 1.00 x 10 ^23 molecules
<em>by cross multiplication</em>
= (1 mole x 1.00 x10^23 molecules) / ( 6.02 x 10^23 molecules)
=0.166 moles of N2
Step 2 : find mass of N2
Mass = moles x molar mass
From periodic table the molar mass of N2 = 14 x2 = 28 g/mol
mass = 0.166 moles x 28 g/mol = 4.648 g
Answer:
The mass percentage of CaCO3(s) in the sample is 83.4%
Explanation:
CaCO₃ + 2HCl → CaCl₂ + H2O + CO₂
Let's find out the moles of each reactant:
[HCl] = 0.150 mol/L
Molarity . volume = moles
0.150 m/L . 0.050L = 7.5x10⁻³ moles HCl
Molar mass of CaCO₃ =100.08 g
Moles of CaCO₃ = Mass / Molar mass
0.450 g/100.08 g = 4.49x10⁻³ moles of salt
Ratio is 1:2
If 2 moles of HCl react with 1 mol of salt
7.5x10⁻³ moles of HCl react with 7.5x10⁻³ / 2 = 3.75x10⁻³ moles
We must find out the mass
Moles of CaCO₃ . Molar mass CO₃ = 0.3753 g
So now, the mass percentage of salt will be
0.450g ___ 100%
0.3753 g ____ (0.3753 .100 )/0.450 =83.4 %
2. High tempertaure and low pressure
3. HCL,NH3,H20
4. higher collisions ieThe greater the number of gas molecules, higher will be the collision rate and hence the greater the pressure.
Explanation:
Expansion:
1. Suppose gas particles are moving in a linear fashion but if they collide with some thing they will fil that. This explains expansion theory of gases.
Fluidity: The gas molecules are in dependent of each other and have low density, they are in constant motion hence have fluidity.
low density: The gas molecules are far apart as compared to solid and liquid hence have low density.
compressibility: Due to the large distance between the gas molecules they collide with each other and vessel wall and when the space is constricted they start moving faster. They are elastic in nature.
Diffusion: Yes, because when gas is mixed it starts moving in the mixture randomly.
2. The molecules in real gas are at large distance. The high temperature and low pressure real gas would behave ideally. Because increase temperature would cause higher movement of gas particles.
3. HCL, NH3 and H2O are polar gases they will have relatively different attractive forces between them.
4. The greater the number of gas molecules, higher will be the collision rate and hence the greater the pressure.
5. The gas particles get closer, enough pressure not provided. It increases the kinetic energy as heat is produced due to compaction of molecules. The particles would not move and will become liquid causing volume to increase.
6. The gas molecules start moving rapidly, move farther apart .Volume and pressure also increases.
