Answer:
8 electrons
Explanation:
As per the <u>octet rule</u>, the atoms possess a tendency to bond in a manner that every atom must have at least eight(8) electrons in its outermost/valence shell. It can be done either by sharing, gaining, or losing electrons from one atom to another. According to this rule, flourine would have 8 electrons in its outer shell after two shared electrons are given to it.
Δt = i Kf m
2.86 °C = (1) (1.86 °C kg mol-1) (x / 0.750 kg)
2.86 °C = (2.48 °C mol-1) (x)
x = 1.1532 mol
33.7 g / 1.1532 mol = 29.2 g/mol
Answer:
Reaction products are shown below
Explanation:
- In cannizaro reaction, benzaldehyde produces benzoic acid and benzyl alcohol through disproportion.
- Here, a hydroxyl group first gives a nucleophilc addition at carbonyl center of benzaldehyde.
- Then a hydride transfer takes place to another molecule of benzaldehyde
- Thus, benzoic acid and benzyl alcohol are produced.
- Full reaction mechanism has been shown below
In an exothermic reaction, heat is released. ΔH for an exothermic reaction is negative. That means that the energy stored in the reactants is higher than the energy stored in the products.
The opposite is true for an endothermic reaction. Heat is absorbed, and <span>ΔH for an endothermic reaction is positive. This means that energy stored in the products is higher than the energy stored in the reactants.</span>
N(Mg) : n(O)
1 : 1
the ratio is one to one
