The answer is Desert. The <span>biomes that likely has the thinnest layer of topsoil is the Desert. </span>The topsoil is a very important layer of soil because on this <span>layer of soil, plants are nourished. The topsoil have to be healthy to grow plants on it. It contains humus, bacteria, fungi, insects and worms.</span><span> But you can hardly find these in the Desert.</span>
So diffusion is inversely proportional to mass !
so as mass of the particle increases, diffusion decreases !
<span>The reaction leads to carbon dioxide gas.
</span><span>It releases CO2 bubbles and leftover of sodium nitrate solution.</span>
You have to convert the mass from g to kg since the unites for a joule is kgm²/s². When you do this you should have E=(1.0×10⁻⁷ kg)×(3.00×10⁸ m/s)². With that E=9.00×10⁹J which equals 9.00×10⁶kJ.
I hope this helps. Let me know if anything is unclear.
