Answer:
Explanation:
The monochlorination of n-butane gives two products out of which one is optically active with one chiral carbon atom. Thus, there are 3 products are obtained
It usually leads to Global warming .
Answer:
Final temperature of object = 25°C
Explanation:
Given data:
Final temperature of object = ?
Mass of object = 10 g
Specific heat capacity of object = 1 cal/g.°C
Heat content = 50 cal
Initial temperature = 20°C
Solution;
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 = T2 - T1
Now we will put the values in formula.
50 cal = 10 g × 1 cal/g.°C × (T2 - 20°C)
50 cal/ 10 cal/°C = (T2 - 20°C)
5 °C = (T2 - 20°C)
5°C + 20°C = T2
T2 = 25°C
<h3>Answer:</h3>
H₂O
Explanation:
According to Arrhenius Concept of Acid and Base, "Acid is any specie which when dissolved in water ionizes to produce H⁺ ions".
Examples:
HCl → H⁺ + Cl⁻
H₂SO₄ → 2 H⁺ + SO₄²⁻
While, "Bases are those species which when dissolved in water produces Hydroxyl Ions (OH⁻)".
Examples:
NaOH → Na⁺ + OH⁻
Mg(OH)₂ → Mg²⁺ + 2 OH⁻
Given Options:
CH₃OH:
Methanol when dissolved in water does not dissociate as follow,
CH₃OH → H₃C⁺ + OH⁻
Hence, it does not behave as Arrhenius Base.
CH₃COOH:
Acetic acid when dissolved in water produces H⁺ ions and Acetate ions i.e.
CH₃COOH → CH₃COO⁻ + H⁺
Therefore, it can act as Arrhenius Acid instead of Arrhenius Base.
H₂O:
Water when dissolved in water dissociates as,
H₂O → H⁺ + OH⁻
As it is producing both H⁺ and OH⁻ ions therefore, it can act as both Arrhenius Base and Arrhenius Acid.
H₂NNH₂:
Hydrazine when dissolved in water can neither produce OH⁻ ions nor H⁺ ions hence, it is neither Arrhenius Base nor Arrhenius Acid,
