Winds in the Northern Hemisphere shift in a clockwise direction. What cause this change in direction?
mina [271]

Answer:

The earth rotates on its axis from west to east. This rotation causes both the wind and ocean currents to move from east to west. Thus, the wind movement and ocean currents in the northern hemisphere goes clockwise and counter clockwise in the southern hemisphere.

Because Earth rotates on its axis from west towards the east, air near the surface from the tropics is moved toward a westerly direction (toward the right as it is often called) in the northern hemisphere. Notice the difference between the lines drawn when the globe did not move (shown with arrow heads) and the lines which were drawn as Earth rotated.

Transition metals have delocalized electrons called an "electron sea." What property does this allow?
RideAnS [48]

Answer:

A conducting electricity

Explanation:

The "electron sea" allows the current to flow across the electrons. If the electrons were stuck in their positions, these metals would be better insulators than conductors because they couldn't spread (or <em>conduct) </em>the energy as electricity.

B, C, and D are all not things directly caused by the delocalized electrons.

amid [387]
Above is a potential energy curve of a reaction. It depicts conversion of reactant to product via transition state.

When a catalyst is added to the reaction system, energy barrier of reaction decreases.

It must be noted that energy barrier reaction is defined as energy difference between  reactant and transition state.

In present case, energy of reactant is 200 kj, while that of transition state (in absence of catalyst) is 650 kj

Thus, energy barrier of reaction is 650 - 200 = 450 kj

<span>Hence, system must absorb 450 kj of energy for the reaction to start, if no catalyst was used</span>

A 1 l container contains O2 gas at stp. if the diameter of the O2 molecule is 3.75 * 10^-10 m the mean free path of the o2 molec
Luba_88 [7]

The mean free path of the O₂ molecule is 5.97*10^{-5} m.

The mean free path of the O₂ molecule is calculated by the formula -

λ = \frac{1}{\sqrt{2}*\pi *d^{2}*n}

In this formula, λ represents mean free path of gas, d represents diameter and n is number of molecules.

As per the known fact, 1 mole of gas occupies 22.4 liter at STP.

So. 1 liter of O₂ gas will have number of moles = \frac{1*1}{22.4}

Number of moles = 0.045

Also, we are aware that 1 mole contains 6.02*10^{23} molecules.

So, 0.045 moles will contain number of molecules = 6.02*10^{23}*0.045

Number of molecules = 2.7*10^{22} molecules

Now, keeping the values in formula to find mean free path of gas -

λ =  \frac{1}{1.4*3.14*(3.75*10^{-10})^{2} *2.7*10^{22} }

λ = \frac{1}{16746.7}

λ = 5.97*10^{-5} m

Hence, the mean free path of the O₂ molecule is 5.97*10^{-5} m.
