Answer:</h3>
2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂
<h3>
Explanation:</h3>
- A decomposition reaction is one in which a large compound is broken down into smaller compounds or individual elements.
- The decomposition reaction Iron (iii) hydrogen carbonate yield iron (iii) carbonate, water and carbon dioxide.
Fe(HCO₃)₃ → Fe₂(CO₃)₃ + H₂O + CO₂
- A balanced equation is the one in which the number of atoms of each element are equal on both side of the equation.
- Therefore; the balanced equation for the decomposition of Iron (iii) hydrogen carbonate is given by;
2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂
2. B) electrical chemical thermal mechanical
3. B) light, sound, and heat
4. A) light energy from the sun
Ok so I’m going to break it up so it’s a bit easier to read through:
The colours are from the different rocks and minerals that make up the sand.
The little fragments of rock come from for example surrounding mountains.
It could also because sand is simply the product from erosion of the rocks rubbing each other under the action of the waves.
So if the bottom of the ocean is made of black lava for example in Hawaii, there’s a good chance of the sand being black.
In California, the sand usually looks white because it has minerals like quartz and pieces of shell that are made of calcium carbonate.
Hope this helps :)
