Answer:
D. 2.5 × 10–4 M
Explanation:
Data given in the question are;
rate constant of 5.0 × 10–2 mol/L·s
[A]0 = 1.0 × 10–3 M
5 × 10–3 sec
It was mentioned that the reaction is a zero order reaction. One interesting charaacteristics about zero order reactio is that the rate of reaction is indepenedent on the concentrations of the reactants.
This means in zero order reactions, we have;
Rate = Rate constant
Rate = 5.0 × 10–2 mol/L·s
What is the concentration of B after 5 × 10–3 sec?
Concentration = Rate * Time
Concentration = 5.0 × 10–2 * 5 × 10–3
Concentration = 2.5 × 10–4 M
Correct option = D
Answer: Skeletal System
Explanation: Sense It's Sending up a signal up Joaquin's spinel cord It must be traveling threw his skeletal system
The dispersed particles of a colloid exhibit brownian motion, in which they move in a chaotic manner without a discernible pattern. The brownian motion is the erratic random motion of particles that are suspended in a fluid which results to the collision of molecules moving fast in the fluid they are in.
By the transfer of one or more electrons from one atom to another
for example,
2Na + Cl₂ → 2Na⁺Cl⁻
Na - e⁻ → Na⁺
Cl₂ + 2e⁻ → 2Cl⁻
