Answer:
sp²
Explanation:
You need to look at how many electron orbitals around the atom. Looking at the structure below, you can see that there are three electron orbitals. This gives you an sp² hybridization.
Answer:
Explanation:
Hello!
In this case, since we know the balanced chemical reaction, we are first able to realize there is a 1:3 mole ratio between zinc phosphate and zinc chloride; it means that we can first compute the moles of the desired product via stoichiometry:
Next, since those moles are associated with the theoretical yield of zinc chloride, we obtain the corresponding mass:
Finally, we compute the percent yield by diving the actual yield (18 g) by the theoretical yield:
Best regards!
The correct answer is c. H3PO4 2H++ HPO42¯(Phosphoric acid)
<h3>
Phosphoric acid</h3>
Known also as ortho-phosphoric acid, phosphoric acid is a triprotic acid that occurs as a viscous liquid. It irritates or corrodes human skin, eyes, and other mucous membranes as well as those of experimental animals. However, the irritancy potential of its salts is much smaller. When mice were exposed through inhalation, moderate toxicity was seen. Both phosphate salts and phosphoric acid have been shown to enhance the action of recognized carcinogens, however phosphoric acid alone is neither genotoxic nor carcinogenic. Typically, irrigation or water flushing are used to treat exposures. As a food addition to different cola drinks, phosphoric acid has attracted a lot of attention but also generated a lot of debate due to its potential for negative effects.
