Answer:

uhh

Explanation:

Wegener found similar evidence when he discovered tropical plant fossils in the frozen region of the Arctic Circle. As Wegener collected more data, he realized the explanation that best fit all the climate, rock, and fossil observations involved moving continents.

Where would the temperature of the ocean's surface water be the lowest?
bazaltina [42]

Answer:

The correct answer is option C, areas with a high salinity

Explanation:

The higher the density of the ocean water, the lower will be the temperature. The highly saline ocean water thus exists in the polar regions than the tropic regions. Due to high density the cold water seeps down and thus it further becomes cooler while a low density ocean water remains at the surface and possess additional heat

A box contains 104 gas molecules, 2500 of nitrogen and 7500 of argon in thermal equilibrium. The molecular weight of N2 is 28g/m
LekaFEV [45]

Answer : The temperature of this gas will be, 206.9 K

Explanation :

The expression for the kinetic energy per molecule of monoatomic gas (argon) is:

K.E_{argon}=n_{argon}\times \frac{3}{2}\times K_BT      ...........(1)

The expression for the kinetic energy per molecule of diatomic gas (nitrogen gas) is:

K.E_{nitrogen}=n_{nitrogen}\times \frac{5}{2}\times K_BT      .............(2)

The total kinetic energy of the molecule will be,

K.E_{Total}=K.E_{argon}+K.E_{nitrogen}

Now put all the expression in this, we get:

K.E_{Total}=(7500)\times \frac{3}{2}\times K_BT+(2500)\times \frac{5}{2}\times K_BT

T=\frac{K.E}{17500\times K_B}

Now put all the given values in this expression, we get:

T=\frac{5\times 10^{-17}J}{17500\times (1.381\times 10^{-23}J/K)}

T=206.9K

Therefore, the temperature of this gas will be, 206.9 K

What is harder to pull apart a sodium ion from a chloride ion or a potassium ion from a chloride ion?
madreJ [45]
<span>Hydrogen ion, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. Thehydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton. The isolated hydrogen ion, represented by the symbol H +, is therefore customarily used to represent aproton.</span><span>
