It is based on the law of conservation of energy , which says that energy is neither created nor destroyed during a chemical reaction . I’m calorimeter , this means that the heat gained by the water in calorimeter must have been released by the sample or reaction taking place in the calorimeter .

It is based on the law of conservation of energy, which says that energy is neither created nor destroyed during a chemical reaction. In calorimetry, this means that the heat gained by the water in the calorimeter must have been released by the sample or the reaction taking place in the calorimeter

alexandr1967 [171]

Answer:

The ration of molar concentration is "2.5".

Explanation:

The given values are:

Average density of salt water,

= 1.03 \ g/cm^3

Net pressure,

= 2.00 \ atm

Increase in pressure,

= 1.00 \ atm

Now,

The under water pressure will be:

=  \frac{15 \ m}{10}\times 1 \ atm +1 \ atm

=  1.5\times 1+1

=  1.5+1

=  2.5 \ atm

hence,

The ratio will be:

=  \frac{(\frac{n}{V})_{15m} }{(\frac{n}{V})_{surface} }

or,

=  \frac{P}{P_s}

=  \frac{2.5}{1}

=  2.5

Which type of reaction occurs in the following equation?
Tema [17]
The  type  of  reaction  which  occurs  is  referred to  as  redox  reaction.  This  kind  of  reaction  involve  both  oxidation  and  reduction.
Al(s)  is  oxidized  to  alluminium  ions,  while  cu2+  is reduced  copper metal.Reduction  occurs   at  the  cathode  while oxidation  occurs at  the anode.

An X-ray beam with λ = 157 pm incident on the surface of a crystal produced a maximum reflection at an angle of θ = 28.5 ∘. Assu
WARRIOR [948]

Answer:

The separation between layers of atoms in the crystal is 164.52 pm.

Explanation:

Formula used

n \lambda = 2d\sin \theta (Bragg's law)

Where :

n = an order of reflection (integer)

\lambda = wavelength of the beam incident X-ray

d = spacing between the layer

θ = incident angle ( angle between ray and scatter plane)

We have :

λ = 157 pm

θ = 28.5°

n = 1

d = ?

1\times 157 pm= 2d\sin (28.5^o) (Bragg's law)

d=\frac{1\times 157 pm}{2\times \sin (28.5^o)}=164.52 pm

The separation between layers of atoms in the crystal is 164.52 pm.
