1. Do you know what is Aliquot and Diluent?
Aliquot : It is a measured sub-volume of original sample
Diluent: Material with which sample is diluted
Mole is the unit used to define the number of chemical substance present in a substance. It is the amount of substance which consists of the same number of chemical units as there are atoms in exactly 12 gram of pure carbon-12.
A valency is a property of a groups or atoms, equal to the number of atoms of hydrogen that the group or atom could combine with or displace it in forming compounds.
4. Please tell me what is the monomer of polyethene?
The monomer of polyethene is ethylene
5. Tell me what is dextro-rotatory and levo-rotatory?
Levorotation and Dextrorotation is referred to the properties of plane polarized light, when light rotates clockwise when it approaches the observer is then known as dextro-rotation and when the light rotates anti-clockwise then it is referred as levo-rotation.
A compound which exhibits a dextro-rotation is referred as dextro-rotatory and which exhibits levo-rotation is referred as levo-rotatory.
6. Tell me does Organic Milk Taste Better?
The taste of milk, regardless of whether it is organically or conventionally produced, can differ slightly from carton to carton and season to season. Factors that may impact taste include location of the farm, breed of the cow, variations in cows' feed from farm to farm, and even the time of year. Milk that is ultra-high temperature pasteurized for longer freshness may have a slightly different taste. People should do their own "taste test" to see what type of milk they prefer.
7. Tell me is Raw Milk Better For Those With Lactose Intolerance?
No. The enzyme required to break down lactose, known as lactase, is produced in the human body and is not present in either raw or pasteurized milk. People with lactose intolerance lack this enzyme. Whether milk is raw or pasteurized is irrelevant to lactose digestibility.
8. Explain me what is molality?
Molality is the number of solute that is present in 1 kg of a solvent.
First step: Convert the volume from millilitres to litres
320 X (1 litre/1000mL) = 0.320 L solution
Second use the formula = M x V
= 5.0 moles glucose/ litre solution X 0.320 L solution
= 1.6 moles of glucose present in 320mL of solution
10. What makes a molecule into organic molecule?
In a molecule when hydrogen atom is less than the ratio of carbon atom, then such molecules are referred as an organic molecule.
11. Why graphite rod is used in nuclear reactor?
Graphite rod is used in nuclear reactor to convert fast moving neutrons into thermal neutrons.
12. Tell us what is iron ore consists of?
Iron ore is consists of Fe2O3
13. Tell me why Do Dairy Farms Smell?
Animals eat, therefore they produce manure. Manure has an odor. Dairy farmers work hard to minimize these odors by maintaining clean facilities, following proper manure storage practices, and properly applying manure as a natural fertilizer for cropland.
In some cases, farms are required to implement an odor management plan. Research and development has inspired new practices and innovative technologies to help farmers maintain clean air for everyone. Dairy farmers care about air quality; their families live and work on their farms and breathe the air, too.
14. Please explain what Do You Call Male And Female Dairy Animals?
Males are called bulls. Females, prior to giving birth, are called calves or heifers. After they give birth, female dairy animals are called cows.
15. Tell us what is the chemical composition of fat in human body?
Fat found in human body is mainly composed of
☛ Glycerides
☛ Glycerides+Phospholipids
☛ Glycolipids
☛ Phosphoinotisides
☛ Tocopherol
To know the amount or volume of NaOH to prepare 400 mL of 1.5 M NaOH, we use formula
M1 X V1 = M2 X V2
V1 = M2 X V2/ M1
But before that we will convert 400 mL into litre = 0.4 L
5.5 X V1 = 1.5 M x 0.4 L
V1 = 1.5 M X 0.4L/ 5.5
V1= 0.10 L
V1 = 100mL
So, you need 100mL of 5.5 NaOH
17. Mention how many millilitre is equal to 1 litre and how many microliter is equal to litre?
☛ 1 millilitre = 0.0001 litre
☛ 1 microliter = 0.0000001 litre
