was necessary for Schrodinger’s work is the Bohr’s model. Unlike the Bohr
model, the quantum model does not define the exact path of an electron. The electron
is likely to be in a less dense area of cloud.</span>
Sorry I can't tell you the answer but, I can tell you something...
Dividing the mass of the water lost by the mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.
How to find it?
Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical actual percent hydration percent water can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.
Answer:
Option (C)
Explanation:
A metal detector is usually defined as an instrument that is commonly used to detect the presence of metals in the bags and luggage. It is very widely used in places like airports, railway stations, and other important official places.
This device is generally activated with the help of electromagnetic induction. It contains a single or numerous inducting coils which are connected to the elements placed on the ground surface. These used materials are metallic in nature. Within the region of the electromagnetic field, when any metallic substance enters, it immediately gains energy and thereby transmits an electromagnetic field of its own.
Thus, the correct answer is option (C).
Nitrogen gas has the chemical formula N2. One molecule of nitrogen gas is made up of two atoms of nitrogen.
The correct option is C.
Explanation:
Nitrogen gas has the chemical formula 
, which means that two atoms of nitrogen element combined to form nitrogen gas.
The combination of two atoms of element nitrogen produce dinitrogen atom.
Dinitrogen is the nitrogen gas usually present in atmosphere of the earth in abundance.
2 atoms of nitrogen element
N + N =
the gas is colorless and odorless formed at standard condition of temperature and pressure. The two nitrogen atoms are tightly bonded with triple bonds in between the atoms.
