I think the answer is a, volume, but I still might be wrong.
Chromium is a fairly active metal. It does not react with water, but reacts with most acids. It combines with oxygen at room temperature to form chromium oxide (Cr 2 O 3 ). Chromium oxide forms a thin layer on the surface of the metal, protecting it from further corrosion (rusting).
Answer:
Covalent
Explanation:
In the carbon tetrachloride molecule, four chlorine atoms are positioned symmetrically as corners in a tetrahedral configuration joined to a central carbon atom by single covalent bonds
10,573.4
Explanation:
Given parameters:
Dosage per patient = 73ap/lbs
Weight of patient = 65.7kg
Unknown:
Amount of grams/ap to be given to the patient;
Solution:
Since our final answer should be expressed in grams, let us convert all units into grams.
1000g = 1kg
Converting 65.7kg to g = 65.7 x 1000 = 65700g
73ap/lbs;
1lb = 453.6g
73ap/lbs x 
= 0.161ap/g
Now,
For a 65700g person, the number of grains app required;
65700 x 0.161 = 10,573.4grains ap per dose

<span>Define a Potassium Reaction: A Potassium Reaction involves a process in which Potassium is mixed with another substance which react to form something else. Reactions are manifested by the disappearance of properties characteristic of Potassium and the appearance of new properties in the new substance or Compound. The substances initially involved in a reaction are called reactants or reagents. The most important of the Potassium compounds is Potassium chloride (KCl) which is used in the production of fertilizers and chemicals and also as a salt substitute. Other important compounds are Potassium nitrate (KNO3), also known as saltpeter which is used in the production of gunpowder, fertilizers and pyrotechnics and Potassium hydroxide (KOH) is used to make detergents and soaps. Reactions are described with Chemical Formula and Equations.</span>
