Answer:
The energy of electromagnetic radiation increases as its frequency increases.
The frequency and wavelength of electromagnetic radiation are inversely proportional.
Explanation:
According to Max Plank's equation, the energy of electromagnetic radiation is given by E=hf where h= Plank's constant and f= frequency of the electromagnetic radiation. This means that the energy and frequency of electromagnetic radiation and its energy are related by a direct proportion. As frequency of the electromagnetic radiation increases, the energy of the radiation increases also.
However, frequency and wavelength of electromagnetic radiation are inversely related. The frequency decreases with increasing wavelength of electromagnetic radiation.
Answer:
PART B
1. Polysaccharide
2.Carbohydrates
3. DISACCHARIDE
4. Monosaccharide
PART A
2 is incorrect
Explanation:
PART A
The option 2 is incorrect because it is not in all carbohydrates that the number of atoms of carbon will be equal to the number of atoms of oxygen. This can be seen in the case of sucrose with the molecular formula C12H22O11
PART B
1. A carbohydrate that yields many monosaccharides when hydrolysed is a polysaccharides
2. The general name of any sugar is carbohydrate
3. Lactose is a double sugar meaning it contains 2 monosaccharides or simple sugar and thus when hydrolysed would be splitted into two simple sugars
4. A monosaccharide cannot be hydrolysed further because it’s at the simplest stage of any carbohydrate
Answer:
The periodic table
Explanation:
The periodic table can show the atomic number and atomic mass of any atoms easily. To convert grams of water to moles of water, you need to know the atoms that made up water molecules then find out their molecular mass. Water is made of two hydrogens and one oxygen atoms. Then you can find the atomic mass of hydrogens is 1 while oxygen is 16. The molecular mass of water will be 2*1 + 16= 18g/mol.
(4.99 g) / (3.65 g/mL) = 1.37 mL
The answer to your question is 1.37ml.
Answer:
amount of silver chloride required is 0.015 moles or 2.1504 g
Explanation:
0.1M AgCL means 0.1mol/dm³ or 0.1mol/L
1L = 1000mL
if 0.1mol of AgCl is contained in 1000mL of solution
then x will be contained in 150mL of solution
cross multiply to find x
x = (0.1*150)/1000
x= 0.015 moles
moles of silver chloride present in 150 mL of solution is 0.15 moles
To convert this to grams, simply multiply this value by the molar mass of silver chloride
molar mass of silver chloride AgCl =107.86 + 35.5
=143.36 g/mol
mass of AgCl = moles *molar mass
=0.015*143.36
=2.1504g
=
