Warm air other the ocean moves onshore I think
Aluminum has three electrons in its valence shell. if you look at the periodic table, there are numbers at the top. in column 2, the elements have 2 valence electrons, in column 3 they have 3 valence electrons etc.
<u>Answer:</u> The concentration of hydrogen gas at equilibrium is 0.037 M
<u>Explanation:</u>
We are given:
Initial concentration of HI = 1.0 M
The given chemical equation follows:
<u>Initial:</u> 1.0
<u>At eqllm:</u> 1.0-2x x x
The expression of 
for above equation follows:
![K_c=\frac{[H_2][I_2]}{[HI]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_2%5D%5BI_2%5D%7D%7B%5BHI%5D%5E2%7D)
We are given:
Putting values in above expression, we get:
Neglecting the negative value of 'x' because concentration cannot be negative
So, equilibrium concentration of hydrogen gas = x = 0.037 M
Hence, the concentration of hydrogen gas at equilibrium is 0.037 M
Answer:
Asteroids
At first glance, asteroids may seem like run-of-the-mill space rocks, but these ancient solar system remnants come in all shapes, sizes and flavors
Comets
For millennia, the sight of a comet elicited fear and awe. Ancient astronomers believed comets foretold the death of princes and the outcomes of wars. Modern astronomers know comets are the ice-clad leftovers from the material that formed our solar system billions of years ago.
Meteoroids
Meteoroids are the true space rocks of the solar system. No larger than a meter in size (3.3 feet) and sometimes the size of a grain of dust, they are too small to be considered asteroids or comets, but many are the broken pieces of either. Some meteoroids originate from the ejected debris caused by impacts on planets or moons.
Answer:
Sn^2+(aq)/Sn^3+(aq)//F2(g)/2F-(aq)
Explanation:
In writing the shorthand notation for an electrochemical cell, the oxidation half cell is shown on the left hand side and the reduction half cell is shown on the right hand side. The oxidation half equation reflects electron loss while the reduction half equation reflects electron gain.
