Answer:
2.0 × 10⁴ mg
Explanation:
Step 1: Given data
Mass (m): 0.020 kg
Step 2: Convert the mass from kilograms to grams
We will use the conversion factor 1 kg = 1,000 g.
0.020 kg × (1,000 g/1 kg) = 20 g
0.020 kg is equal to 20 g.
Step 3: Convert the mass from grams to milligrams
We will use the conversion factor 1 g = 1,000 mg.
20 g × (1,000 mg/1 g) = 2.0 × 10⁴ mg
20 g is equal to 2.0 × 10⁴ mg. Then, 0.020 kg is equal to 2.0 × 10⁴ mg.
Answer:
B
Explanation:
stronger gravitational gradient
C
The forward and reverse processes would still be ongoing (the system is not still as in the case of static equilibrium), however, the net effect between the two processes is zero. This is what is referred to as dynamic equilibrium.
A closed system, is one that does not exchange matter or energy between it and the environment.
Explanation:
Take an example of a simplest reversible reaction like the following;
A ⇔ B
To get the dynamic equilibrium constant for the reaction we use the following equation;
Keq = [B]eq / [A]eq
Where eq denotes equilibrium.
An example of a reversible reaction where this applies is;
NH₄Cl (s) ⇔ NH₃ (g) + HCl (g)
