Answer:

Option (A)

Explanation:

The air molecules are densely packed near the surface of the earth and are scattered in the upper atmosphere. It is because of this, the air pressure and temperature near the earth's surface is higher than it is at higher altitudes.

In the given data, A and B are two nearby places, where location A has a higher temperature and B has a low temperature.

This means that A has high pressure, as the air pressure and temperature are directly proportional to one another and as height increases, temperature and pressure simultaneously decrease.

So, it can be concluded that location A experiences a high temperature and high-pressure condition because of its low elevation (height).

Whereas, location B experiences low pressure and low-temperature condition because of its higher elevation.

Thus, both the location A and B will experience different atmospheric pressure.

Hence, the correct answer is option (A).

Which of the following claims may be made based on your observations? (You will recieve negative points for wrong answers.)
Ostrovityanka [42]

Answer:

D, E and F

Explanation:

About tetrachloro cobalt complexes, the following facts have been observed  

  • Color of the tetrachloro cobalt complexes is blue.
  • They do not decompose on heating that means synthesis of tetra chloro is endothermic.

About hexa aqua cobalt complexes, the following facts have been observed  

  • Color of the hexa aqua cobalt complexes is pink color.
  • They decompose on heating and remain stable on cooling that means process of synthesis of hexa aqua cobalt complexes is exothermic.

Based on above, the correct statements are:

The correct is chloro cobalt complex is blue and aqua cobalt  

complex is pink.  

The chloro complex is favored by heating.

If the chloro complex is a product, then the reaction must be endothermic.

The correct options are D, E and F.

The half-life of nitrogen-13 is 10.0 minutes. if you begin with 53.3 mg of this isotope, what mass remains after 25.9 minutes ha
zimovet [89]

Hello!

The half-life is the time of half-disintegration, it is the time in which half of the atoms of an isotope disintegrate.

We have the following data:

mo (initial mass) = 53.3 mg

m (final mass after time T) = ? (in mg)

x (number of periods elapsed) = ?

P (Half-life) = 10.0 minutes

T (Elapsed time for sample reduction) = 25.9 minutes

Let's find the number of periods elapsed (x), let us see:

T = x*P

25.9 = x*10.0

25.9 = 10.0\:x

10.0\:x = 25.9

x = \dfrac{25.9}{10.0}

\boxed{x = 2.59}

Now, let's find the final mass (m) of this isotope after the elapsed time, let's see:

m =  \dfrac{m_o}{2^x}

m =  \dfrac{53.3}{2^{2.59}}

m \approx \dfrac{53.3}{6.021}

\boxed{\boxed{m \approx 8.85\:mg}}\end{array}}\qquad\checkmark

I Hope this helps, greetings ... DexteR! =)
