Acute: Can be repaired by the body using white blood cells.
Chronic: High doses causing internal bleeding and breakdown of cells causing slow death, 90% of the times cannot be fixed by any medicines.
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Thus, given the 1.00-kg of 12.5% ore, we can compute the theoretical yield of copper (II) oxide via stoichiometry:
Whereas the third factor accounts for the percent purity of the covellite. Then, given the percent yield, we can compute the actual yield by:
Regards.
<h3>What is the oxidation number of oxygen in H2O?</h3>
Oxygen almost always has an oxidation number of -2, except in peroxides (H 2 O 2) where it is -1 and in compounds with fluorine (OF 2) where it is +2. Hydrogen has an oxidation number of +1 when combined with non-metals, but it has an oxidation number of -1 when combined with metals.

Answer:
Explanation:
The direct reaction of a carboxylic acid with an amine would be expected to be difficult because the basic amine would deprotonate the carboxylic acid to form a highly unreactive carboxylate. However when the ammonium carboxylate salt is heated to a temperature above 100 C water is driven off and an amide is formed.
