The correct answer is D : United States

All of the other countries on the list have great species diversity, especially Cosa Rica due to it's closeness to the equator and therefore its tropical climate perfectly suitable for wildlife thrive.
But, the United States' territory covers the areas with the mild climate, forests, deserts, canyons and species-rich coastal regions as well as the Hawaii islands with unique species diversity and the Alaskan area with the arctic habitat.

Suppose two 200.0-L tanks are to be filled separately with the gases helium and hydrogen. What mass of each gas is needed to pro

Aneli [31]

Answer:

Mass of helium = 4426.9524 g

Mass of hydrogen gas = 2213.4762 g

Explanation:

Pressure = 135 atm

Temperature = 24 °C

Volume = 200 L

Number of moles = ?

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T₁ = (24 + 273.15) K = 297.15 K

Using ideal gas equation as:

PV=nRT

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the equation as:

135 atm × 200 L = n × 0.0821 L.atm/K.mol × 297.15 K

⇒n = 1106.7381 moles

For helium gas:

Molar mass = 4 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$1106.7381= \frac{Mass}{4}$

$Mass= 4426.9524\ g$

For hydrogen gas:

Molar mass = 2 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$1106.7381= \frac{Mass}{2}$

$Mass= 2213.4762\ g$

How can u detect the which d-orbital is used in making bond ??

zavuch27 [327]

This is much more simple than it sounds...

s has 1 orbital; p = 3 orbitals; d= 5 orbitals; f= 7 orbitals. (you just need to memorize this)
A maximum of 2 electrons can occupy each orbital.

The number of orbitals that each atom has is based on the number of electrons it has and by consequence it's position on the periodic table. 

The orbitals occur in sequence. Whereby electrons fill first from the lowest energy level (1s) outwards to the highest.
3p = the following sequence.
1s, 2s, 2p, 3s, 3p: these 'sets' can hold the following electrons respectively (2+2+6+2+6) 18 which corresponds with argon on the periodic table. REMEMBER p has 3 orbitals, d has 5 orbitals. So, here there are 9 orbitals.

The sequence through n=4 is:

1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f

Answer: 0.9375 g

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Moles of solute}={\text{Molarity of the solution}}\times{\text{Volume of solution (in L)}}$ .....(1)
