That is your ANSWER.........

We are given that the RING is made up of 20 carrat gold. 20 carrat gold means 20 PARTS of gold and 4 parts of other metal (usually COPPER or silver). Thus, the percentage of gold in 20 carrat gold will be

= (20 / 24) X 100

= 83.333 %

We can now calculate the mass of gold in the ring. We are given that the ring weighs 300 mg. So, the mass of gold in ring will be

= (83.333 / 100) X 300

= 250 mg

Thus, the mass of gold in 300 mg of the ring is 250 mg. 

Now the molar mass of gold is 197 g. This means that there are 6.023 X 1023 ATOMS of gold in 197g of gold. Thus

197g of gold = 6.023 X 1023 atoms of gold

1g of gold = (6.023 X 1023 ) / 197 atoms of gold

250 mg or 0.25g of gold = (6.023 X 1023 X 0.25) / 197 atoms of gold

= 7.643 X 1020 atoms of gold

0.375 M aqueous solution of SODIUM acetate

≡ 1000 ML of solution containing 0.375 moles of sodium acetate

∴Number of moles of sodium acetate in 500 mL

 

MOLAR mass of sodium acetate = 82.0245 g mole–1 (Given)

∴ Required mass of sodium acetate = (82.0245 g mol–1) (0.1875 mole)

= 15.38 g

We know that 22.4 L of CO at stp is equal to 1 Mole

So 112 L of CO is equal to 5 MOLES.

        Now, 2 CO + O2  ==> 2 CO2

So,we need 1 mole of OXYGEN for 2 moles of CO to burn.  So for 112L of CO we need 2.5 moles of O2.

Decomposition of Chlorate is as follows:
        2 K Cl O3  => 2 KCl + 3 O2

Hence,3 moles of Oxygen are obtained from 2 moles of KClO3.

 And we get 2.5 moles of Oxygen from  2.5*2/3 = 5/3 moles of KClO3.

As, Molecular mass of KClO3 = 122.5 gms/mole 

Therefore,the AMOUNT of KClO3 REQUIRED = 122.5*5/3  gms

Sub: Requesting for additional water pipeline connection -regarding.


Sir,

I WISH to bring to your KIND notice that I have only one water pipeline connection. There are three families living in my house INCLUDING two tenants. The water getting from a single pipeline is insufficient for us. As we are facing hardship in managing the AVAILABLE water in our day to day activities. In addition to that we have no any other alternate source of water. I have applied for the same in the last monsoon season but till date no action has been initiated and lying in pending. Hence, I request you to provide one more additional water pipeline connection at your END and oblige. I shall be highly grateful to you for your kind help in this regard. 

Thanking you,

Yours faithfully,

Heteroatoms are elements that REPLACE one or more hydrogen or carbon atoms in an organic compound, such that the overall VALENCY remains satisfied

hope it is USEFUL  to you :):):):):)

Functional GROUPS in organic chemistry are those which are RESPONSIBLE for the changes in the physical and chemical PROPERTIES of an organic compound.

I THINK it will be DECREASING acceleration
bcoz as it MOVES AWAY from another positive charge it decreases its REPULSION

I THINK your QUESTION is INCOMPLETE..

Percentage of CARBON in ORGANIC compound = 69 %

So, 100 g of organic compound CONTAINS 69 g of carbon.

∴ 0.2 g of organic compound will contain = 69 x 0.2 /100 = 0.138 g of carbon

Molecular mass of carbon dioxide, CO2 = 44 g

So, 12 g of carbon is CONTAINED in 44 g of CO2.

∴0.138 g of carbon will be contained = 44 x 0.138/12 = 0.506 g of carbon

Thus, 0.506 g of CO2 will be produced on complete combustion of 0.2 g of organic compound.

Here is your ANSWER...
HOPE this will HELP you....

It is DUE to FORMATION of ammoniated ELECTRONS

the irons are reacting with the acids (citric.) to form SOLUBLE and INSOLUBLE iron oxides (hydroxides), iron  citrates and other acid (citric acid) pairs with the iron  and there are likely REACTIONS with the limonenes, TERPENES and other constituents in the juice.

remember that citric acid are in lemon juice :):):):):):):)

Hey here is your answer
________________________-

your answer is "1.8L"

explaination

10% glucose means 10g
=10/180 moles in 100 CC i.e,0.1 LITRE

(molecular Weight of glucose = 180)


Hence
1 mole of glucose will present in
0.1×180/10 =1.8L

hope it will HELP you..

I THINK ANSWER is 5.188
density=Z×M/a3×avagadro no
=2×100/{400×10power-10}3

Yes UNLIKE ordinary FIRE THERMITE REACTION can not be stopped by pouring water because thermite reaction contains hydrogen and oxygen

Melting POINT of a SUBSTANCE means the TEMPERATURE at which the substance starts melting. for EXAMPLE : melting point of ice 0°C

Chemical FORMULA of ALLUM KAI(SO4)2 .12H2O .

The particle that J.J.Thomson discovered in 1897, the ELECTRON, is a CONSTITUENT of all the MATTER we are surrounded by. All atoms are made of a nucleus and electrons. He received the Nobel Prize in 1906 for the DISCOVERY of the electron, the first elementary particle.

Hey

here is your answer


EVAPORATION usually occurs on the surface. Evaporation MAY occur when the partial pressure of vapor of a SUBSTANCE is less than the equilibrium VAPOUR pressure. 



BOILING is a phase transition from the liquid phase to gas phase that occurs at or above theboiling temperature.


hope it helps u

Everything has its own MELTING point

Example: IRON melts at 1300°C
ICE melts at 0°C


THIS IS THE CORRECT ANSWER SO MARK BRAINLIEST ✌️

It has an atomic mass of 1.00794 AMU, which makes HYDROGEN the lightest element on the PERIODIC table. Hydrogen, H, was named by Laviosier and is the most abundant element on the periodic table.

The AMOUNT of a substance whose mass in grams is numerically EQUAL to atomic mass. this atomic mass expressed is in GRAM so that's why is CALLED gram atomic mass

If we burst coal in the closed room the the coal
which has co2 is converted into carbon MONO OXIDE  gas which is the harmful gas

this gas effect on human BEINGS because the the concentration of carbon monoxide is high compared to O2 OXYGEN to form hemoglobin

hope it helps

HERE IS YOUR ANSWER:-

To calculate the mass of a single atom, first look up the atomic mass of carbon from the PERIODIC Table.
This NUMBER, 12.01, is the mass in grams of one mole of carbon. One mole of carbon is 6.022 X 1023 atoms of carbon (Avogadro's number). This relation is then used to 'convert' a carbon atom to grams by the RATIO:

mass of 1 atom / 1 atom = mass of a mole of atoms / 6.022 x 1023 atoms

Plug in the atomic mass of carbon to solve for the mass of 1 atom:

mass of 1 atom = mass of a mole of atoms / 6.022 x 1023

mass of 1 C atom = 12.01 g / 6.022 x 1023 C atoms
mass of 1 C atom = 1.994 x 10-23 g
