2nd group of the periodic table
Answer:
D) 4.8 × 10² M/s
Explanation:
Let's consider the following generic reaction.
A → B
The rate law is:
v = k . [A]ⁿ
where,
v: velocity
k: rate constant
[A]: concentration of the reactant A
n: reaction order for A
<em>What is the velocity of a first-order reaction when the reactant concentration is 6 × 10⁻²M and the rate constant is 8 × 10³s⁻¹?</em>
v = k . [A]¹ = 8 x 10³s⁻¹ . 6 x 10⁻²M = 4.8 × 10² M/s
Answer:
Gold
Explanation:
Cranberry glass or 'Gold Ruby' glass is a red glass made by adding gold salts or colloidal gold to molten glass. Tin, in the form of stannous chloride, is sometimes added in tiny amounts as a reducing agent.
Answer:
Option C
Explanation:
According to Hund's rule
- pairing of electrons occur first in lower energy orbitals then in orbitals having higher energy.
d subshell has 5 orbitals.
- so first these 5 get filled.
- The. one will be added to first one.
