Here are some rules:
1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.
The oxidation number of Fe in Fe(NO3)2 is +3.
Answer:
tertiary
Explanation:
tertiary halogenoalkanes are more reactive than primary and secondary as the carbocation is more stable due to alkyl groups( have high electron density) donating electrons to stabilise the carbocation
Answer:
10460J
Explanation:
Given parameters:
Mass of water sample = 100g
Initial temperature = 35°C
Final temperature = 60°C
Unknown:
Amount of energy absorbed by water = ?
Solution:
The amount of energy absorbed by water is mathematically expressed below;
H = m C ΔT
H is the amount of energy
m is the mass
C is the specific heat capacity of water = 4.184J/g°C
ΔT = 60°C - 35°C = 25°C
Now insert the parameters and solve;
H = 100 x 4.184 x 25 = 10460J
Answer:
D. It is considered to be a different element than a neutral Sc atom.
Answer:
192g
Explanation:
so for this find out there moles of CH4 by moles=mass/mr
48/16=3 then use molar ratio 1:2 so times it by 2 which is 6 moles. then uses mass =moles*mr so 6*32=192g is the answer hope this helps to understand.
