What is the moisture content of hard gelatin capsule?​
insens350 [35]

Answer:

The standard moisture content specification for hard gelatin capsules is between 13 % w/w and 16 % w/w.  This value can vary depending upon the conditions to which they are exposed: at low humidity's they will lose moisture and become brittle, and at high humidity's they will gain moisture and soften.

Explanation:

Hope this helps!

Describe the differences in the tlc of the reaction mixture before heating and after heating and explain the observed change in
AVprozaik [17]

Using a thin stationary phase supported by an inert backing, thin layer chromatography (TLC) is a chromatographic technique used to separate the components of a mixture.

It can be carried out on an analytical scale to track the development of a reaction or on a preparative scale to purify minute quantities of a chemical. Because of its simplicity, comparatively low cost, great sensitivity, and rapid separation, TLC is an extensively used analytical method. Similar to all chromatography, TLC works on the premise that a chemical will have varying affinities for the mobile and stationary phases, which will influence how quickly it migrates. TLC aims to produce well-defined, well-separated spots.

A wave is best defined as
vladimir1956 [14]

Answer:

A wave is a physical phenomenon characterized by its frequency, wavelength, and amplitude. In general, waves transfer energy from one location to another, in which case they have a velocity. Standing waves may also occur; these have no net velocity and involve no net transfer of energy.

If the electronnegavity difference between elements A and X is 0.8, the bond in AX will most likely be what?
siniylev [52]

Answer:

Polar covalent bond

Explanation:

When the electronegativity difference between two elements A and X is 0.8, the bond AX formed will most likely be a polar covalent bond.

A polar covalent bond is one whose electronegativity difference is between 0.5 and 2.1.

In such a bond type, we have heteronuclear species with one of the species having a higher electronegativity value.

  • When electronegativity difference is less than 0.5, a non-polar covalent bond forms.
  • If the value is greater than 2.1, an ionic bond will form.
