alina1380 [7]

Answer:

The dog should be given half of 100 mg tablet in the morning and another half of 100 mg tablet in an evening.

Weight of the dog = 50 pounds = 22.68 kg

1 kg = 2.205 pounds

Amount of daily dose prescribed by doctor = 4.4 mg/kg

Total mount of dose = 4.4 mg/kg × 22.68 kg = 99.79 mg

99.79 mg ≈ 100 mg

49.89 mg ≈ 50 mg

So, according to doctor prescription dog should be given half 100 mg tablet in the morning and another half of 100 mg tablet in an evening.

Classify unopened root beer as an element, a compound, a homogeneous mixture, or a heterogeneous mixture
maxonik [38]

The different state of material based on its ingredients are-

1. Compound: The compound is in which there are more than one molecule in which chemical bond is there.

2. Mixture: It is basically presence of two or more compounds in which there is no chemical bonds.

The mixture may be of two types (i) homogeneous and (ii) Heterogeneous. In the homogeneous mixture there is uniformity of the mixed compound (like air in water) and some chemical process is needed to separate the compounds. Whereas heterogeneous mixtures (like chalk in water) are easily separable by any physical process.

In the root beer which is a soft drink which is obtained in different flavor sometime with caffeine and without caffeine. The unopened bottle of root beer is homogeneous mixture.
