Answer:

1). MOLE fraction of sugar in syrup = 1/101

2). Molality of sugar in syrup = 0.5 mol/ kg

>> NOTE : MOLARITY CAN'T BE CALCULATED WITH GIVEN MASS, IT IS ONLY CALCULATED WITH VOLUME, BUT MOLALITY CAN BE CALCULATED.

Explanation:

1). Mole fraction :

>>no. of moles of sugar(SOLUTE)/total moles of solution(solution)

(1). sugar = C12H22011

Weight of sugar = 34.2g (given)

Molar mass of sugar = 342 g/mol

Vol 82

>> mole of sugar = 34.2/342 = 1/10 mole

(II). Water = H2O

Weight of water = 214.2-34.2=180 g Molar mass of water = 18 g/mol

>> mole of water = 180/18 = 10 mole

Now,

>> Mole fraction = (1/10)/(101/10)

= 1/10 × 10/101

[Answer] = 1/101 [ Mole fraction

is a unit less quantity]

Vol 82

V

2). Molality

>> If mass is given in gram then,

Molality (weight of solute × 1000)/ = (Molar mass of solute × weight of solvent)

Hence,

weight of solute (Sugar) = 34.2 g (Given)

weight of solvent (water) = 180 g (Given)

Molar mass of solute = = 342 g

» (34.2 x 1000)/(342 × 180)

= 34200/61560

= 0.5 mole/Kg [Answer]

Answer:

HEISENBERG's principle-

It is impossible to measure the value of simultaneous velocity and position of any electron.

By taking UNCERTAINTY principle relationship-

Delta Energy × Delta TIME = h/4Pi , where h is plank's constant

Also, mass× velocity× displacement = energy × time

Thus, 1MG × Delta V × Delta x = h/4pi

Delta v × Delta x = h/4pi × 10^6

हाइड्रोक्लोरिक अम्ल एक प्रमुख अकार्बनिक अम्ल है। वस्तुतः हाइड्रोजन क्लोराइड गैस के जलीय विलयन को ही हाइड्रोक्लोरिक अम्ल कहते हैं।

इस अम्ल का उल्लेख ग्लौबर ने १६४८ ई. में पहले पहल किया था। जोसेफ़ प्रीस्टली ने १७७२ में पहले पहल तैयार किया और सर हंफ्री डेवी ने १८१० ई. में सिद्ध किया कि हाइड्रोजन और क्लोरीन का यौगिक है। इससे पहले लोगों की गलत धारणा थी कि इसमें ऑक्सीजन भी रहता है। तब इसका नाम 'म्यूरिएटिक अम्ल' पड़ा या जो आज भी कहीं कहीं प्रयोग में आता है।

Answer:

NaCl is more IONIC than AlCl3. In NaCl, both Na and Cl will have an equal CHARGE. In AlCl3, the charge of the cation Al3+ is higher when compared to Na+ while the anion Cl is the same in both the compounds. Therefore, ACCORDING to Fajan's rule, AlCl3 is more covalent than NaCl.so A is correct .

The covalent character ALWAYS increases down the GROUP. This is because as the electron cloud moves further away from the nucleus of the atom,it becomes easier to share the electrons with other atoms. And so the covalent character always decreases across a period..so this is also true

Answer:

The nucleus is a collection of PARTICLES called PROTONS, which are positively charged, and neutrons, which are ELECTRICALLY neutral. Protons and neutrons are in turn made up of particles called QUARKS. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.

Answer:

Mass is anything that occupies space and has an amount of matter in it.

Explanation:

The OBJECTS around us are made up of matter. They have mass and occupy space. Mass of a substance is ALWAYS constant. Its SI unit is KILOGRAM.  The mass of a substance is ACCURATELY measured using an ANALYTICAL balance.

The definitions of ELECTRICAL units that were PROPOSED at the 1881 International CONFERENCE of Electricians were designed so that the electromotive force of the Daniell cell would be about 1.0 volts. With contemporary definitions, the standard potential of the Daniell cell at 25 °C is ACTUALLY 1.10 V.
