<u>Answer:</u>
1- Ba(ClO3)2(s) ----> BaCl2(s) +3O2(g) -Redox
2- 2NaCl(aq) +K2S(aq) ----> Na2S(aq) + 2KCl(aq) - None of the above
3- CaO(s) + CO2(g) ------> CaCO3(s) -None of the above
4- KOH(aq)+ AgNO3(aq) -----> KNO3(aq) + AgOH(s) - Precipitation
5- Ba(OH)2(aq) + 2HNO2(aq) -----> Ba(NO2)2(aq) +2H2O(l) -Neutralization.
<u>Explanation;</u>
1) Redox, because it involves bith reduction and oxidation
2) I suppose would be "none of the above" for this chemical reaction, from the choices given.
3) It is a synthesis reaction, thus the correct answer should be "none of the above" from the asker's choices.
4) It is a precipitation reaction, also called double decomposition reaction where two soluble salts react to form an insoluble salt and a soluble salt.
5) It is acid-base neutralization, as such reactions form both a salt and water.
The answer would be C to this question!
The trend of atomic radius in the periodic table is increasing from right to left and from top to bottom. In reference to the table, oxygen has smaller radius compared to carbon, which is smaller than aluminum and which is also smaller than potassium. Thus, the trend from smallest to biggest is oxygen carbon, aluminum and potassium.
Answer:
Nitrogen (N), carbon (C), hydrogen (H) and oxygen (O).
Explanation:
Hello,
Given the shown organic compound, we refer to types of atoms to the elements present in the compound, thus, we find nitrogen (N), carbon (C), hydrogen (H) and oxygen (O) that are bonded via single or double bonds in such compound.
Let's remember that compounds like that, having those elements are mainly found in biochemical substances such as proteins, a very important source of benefits for our body.
Regards.
