Answer: 3
Explanation: I took the k12 quiz
Answer:
Yes
Explanation:
Let's write the reaction as
CV⁺+ OH⁻ ⟶ CVOH
The reaction is first order in [CV⁺] and in [OH⁻], so the rate law is
rate = k[CV⁺][OH⁻]
A bimolecular collision between a crystal violet ion and a hydroxide ion as an elementary step would predict the observed rate law.
However, other plausible mechanisms may predict the same rate law.
An c.ionic bond forms when a cation transfers its extra electron to an anion who needs it.
For example compound magnesium chloride (MgCl₂) has ionic bond (<span>the </span>electrostatic attraction<span> between oppositely charged </span><span>ions)</span>. Magnesium transfers two electrons (became positive cation) to chlorine (became negative anion).
Answer:
option d = 3.125 g
Explanation:
Given data:
Mass of chemical = 100 g
Half life = 8 days
mass left after 40 days = ?
Solution:
First of all we will calculate the total half life's,
half life's = T (elapsed) / T half life
half life's = 40 / 8 = 5
starting mass = 100 g
half life's 1 2 3 4 5
Mass 100/2 50/2 25/2 12.5/2 6.25/2
50 g 25 g 12.5 g 6.25 g 3.125 g
