Answer:
A pill is usually absorbed into the blood through the stomach walls after it is swallowed – these can become active in a few minutes but usually take an hour or two to reach the highest concentration in the blood. IV drugs are injected directly into the blood work much faster – sometimes in seconds or minutes.

Because the all have leaves
Answer:
mass Mg = 1.937 Kg
Explanation:
from periodic table for Mg:
⇒ molecular mass Mg = 24.305 g/mol
∴ mol ≡ 6.022 E23 atoms
⇒ mol Mg = (4.80 E25 atoms)×(mol/6.022 E23 atoms)
⇒ mol Mg = 79.708 mol
⇒ mass Mg = (79.708 mol)×(24.305 g/mol)
⇒ mass Mg = 1937.3 g
⇒ mass Mg = 1.937 Kg
Explanation:
Homogeneous mixture is separated using two stage separation process: mobile stage and stationary stage. The mobile phase are absorbent such as water, chemicals while the stationary stage is the column used for the separation process. The integral method of separation of homogeneous mixtures is called chromatography (analytical or preparative). Other method of separation of homogeneous mixtures is called distillation and it is based on the various boiling points of the component of mixture.
While heterogeneous mixtures are separated based the properties of the components. One method of separation of solids suspended in liquids is simple filtration.
