Answer:
of the reaction is -6313 kJ/mol
of the reaction is -6312 kJ/mol
Explanation:
Therefore, of the reaction is -6313 kJ/mol.
The chemical reaction in bomb calorimeter is as follows.
Therefore, of the reaction is -6312 kJ/mol.
Answer:
28.75211 kj
Explanation:
Given data:
Mass of iron bar = 841 g
Initial temperature = 84°C
Final temperature = 7°C
Heat released = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
specific heat capacity of iron is 0.444 j/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 7°C - 84°C
ΔT = -77°C
By putting values,
Q = 841 g × 0.444 j/g.°C × -77°C
Q = 28752.11 j
In Kj:
28752.11 j × 1 kJ / 1000 J
28.75211 kj
5.5 grams of reactants. According to the Law of Conservation of Mass, mass isn’t created or lost through any chemical changes, so the total mass should remain constant from the initial reactants to the final products.

Answer:
B. s, p, d, f
Explanation:
These things are often referred to as suborbitals and you normally have s,p,d,f.
S has 1 two orbitals
P has 3 orbitals
D has 5 orbitals
F has 7 orbitals
and each orbital can house 2 electrons
