Answer:
i think the answer is b or c
Answer:
D. Water and Carbondioxide
Explanation:
Combustion of organic compounds in the presence of excess Oxygen will liberate carbondioxide (CO2) and water vapour (H2O). This is an exothermic reaction because heat is liberated to the surroundings.
CnH2n+1OH(aq) + (3/2*n)O2(g) --> nCO2(g) + (n + 1)H2O(g)
Addition of Oxygen can also be termed as a redox reaction. In this case, alcohols are oxidised while the Oxygen is reduced.
Example, (propanol)
C3H7OH(aq) + 9/2O2(g) --> 3CO2(g) + 4H2O(g)
Answer:
8 electrons
Explanation:
as the the 1st period (H and He), it can hold up to 2 electrons. in the 2nd period (Li, Be, B, C, N, O, F and Ne), it can hold up to 8 electrons. Itstops at 6 when it reached O. add the lelectrons that you have
2+6=8
8 electrons
The bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order <u>increases</u> or <u>decreases</u> or when its potential energy is at the <u>lowest</u>.
<h3>What is bond length?</h3>
Bond length is also referred to as bond distance and it can be defined as an equilibrium distance between the nuclei of two (2) covalently bonded atoms in a molecule.
<h3>What is bond energy?</h3>
Bond energy can be defined as the amount of chemical energy that is required to break one mole of a given chemical bond.
In Chemistry, the bond length and energy of a molecule is typically determined by the following:
- The bond order or number of bonded electrons.
- The potential energy possessed by the molecule.
In conclusion, you can predict that the bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order increases or decreases or when its potential energy is at the lowest.
