Which is the smallest particle into which water (H2O) in a glass can be broken down and still remain water? A. a water molecule

Gnesinka [82]

Answer:-

A. A water molecule

Explanation:-

A molecule is the smallest particle of a compound that retains all it's chemical properties.

Here H2O is a compound. So the smallest particle that will retain all the chemical properties and still remain water is water molecule.

Atoms Hydrogen and Oxygen both have different chemical properties from water H2O and are thus different.

Hydrogen peroxide is different molecule from water. So it is also not water.

Romashka-Z-Leto [24]

Answer:

Well according to the Law of Evolution, depending on where the Finch lives and what it eats depends on it's beak size. For example, if a Finch lives on the coast and eats small fruits it will have a short and stubby beak to peck at the fruits, but if the Finch ate crabs it's beak would be long to swoop down and pluck up crabs.

Hope this helps!

A highway engineer is researching de-icing compounds for clearing ice from streets in winter. She wants a compound that has +2 i

wolverine [178]

Magnesium combined with chlorine.

How?

Look at the question .Compound has -1 charge in it .Hence it contains Halogen.
Looking at the options Option B and C contain Iodine and chlorine i.e halogens .

Now come to metals side.

Potassium has valency 1(Look the Electronic configuration below)

$\\ \sf\longmapsto 1s^22s^22p^63s^23p^64s^1$

Hence it will contain +1 charge which is omitted directly .

Now come to option C.

Magnesium has charge +2(Look at EC below

$\\ \sf\longmapsto 1s^22s^22p^63s^2$

Hence the compound formed is given by

$\\ \sf\longmapsto MgCl_2$

Hence option C is correct.

A common anesthetic in dentistry known as nitronox consists of a mixture of dinitrogen oxide, n2o, and oxygen gas, o2, which is

Nesterboy [21]

Anesthetic in dentistry consists of a mixture of dinitrogen oxide (N₂O) and oxygen gas (O₂), which is administered through an inhaler over the nose. Total pressure of the mixture ( $P_{total}$ ) is sum of partial pressure of N₂O ( $p_{N_{2}O }$ ) and partial pressure of O₂, ( $p_{O_{2} }$ ).

$P_{total}=p_{N_{2}O } + p_{O_{2} }$

$P_{total}= 740 mmHg, p_{O_{2} }$ =370 mmHg

So, $p_{N_{2}O }$ = (740-370) mmHg= 370 mmHg=370 torr

Hence, partial pressure of N₂O is 370 torr.

As, 1mmHg= 1 torr.
