here can be a number of chemical processes by which a compounds can be broken down into simpler substances. The most common and wide-spread of such processes is Catabolism. Along with anabolism, catabolism make up the metabolism process for living organisms. In catabolism, complex chemical molecules (such as proteins, polysaccharides, etc.) are broken down into simpler molecules (such as amino acids, monosaccharides, etc.). This is often accompanied by release of energy in the form of ATP (adenosine triphosphate) molecules and intermediate metabolites (which can be used by the organism in the anabolic processes). The energy thus generated is used for operation and maintenance of cells (and consequently, the body).
Other processes that break down chemical substances into simpler substances, include depolymerization, decomposition, etc.
Hope this helps.
<span>the K and Cl are 1:1 .. the problem is in the O .. you have 3
(left side) and 2 (right side) .. you multiply the O2 on the right by 3 ..
KClO3 ---> KCl + 3 O2
and now you have 6 O on the right and 3 on the left .. so you multiply the KClO3 by 2 ..
2 KClO3 ---> KCl + 3 O2
now you have 6 O on both sides .. now balance the K and Cl by multiplying KCl on the right by 2 ..
2 KClO3 ---> 2 KCl + 3 O2</span><span>

Answer:
mass = 242.372 grams
Explanation:
1- getting the number of moles of HCl:
molarity = number of moles of solute / liters of solution
4 = number of moles of HCl / 5.2
number of moles of HCl = 4 * 5.2 = 20.8 moles
2- getting the number moles of magnesium:
From the balanced equation given, we can note that one mole of magnesium is required to react with two moles of HCl. To get the number of moles required to react with 20.8 moles of HCl. we will simply do cross multiplication as follows:
1 mole of Mg ...............> 2 moles of HCl
?? moles of Mg ...........> 20.8 moles of HCl
Number of moles of Mg = 20.8 / 2 = 10.4 moles
3- getting the mass of Mg:
number of moles = mass / molar mass
Using the periodic table, we can find that the molar mass of magnesium is 24.305 grams.
This means that:
10.4 = mass / 24.305
mass = 24.305 * 10.4
mass = 242.372 grams

Bromothymol blue is acid base indicator which has pH intervals 6 - 7.6 and its two colors are yellow in acid and blue in basic.
The pH of CaO is about 11.5 to 12.5 this will make the indicator has blue color at the beginning.
By bubbling CO₂ to CaO this leads to formation of CaCO₃ which also basic (pH about 9.5 - 10) so the color of indicator remains blue
No color change of the indicator will observed (remains blue)
There are 8 valence electrons in the Kr atom, this is because Krypton is in the 8th group. Krypton is in the far right row of the periodic table, making it the outermost shell (which is 8 valence electrons)
Hope this helps!
