A strong acid, such as hydrochloric acid cannot be poured down a sink because it will react and dissolve the metal in the pipes.
Nataliya [291]

Answer:

15.2 grams of calcium chloride are produced and HCl is the limiting reactant.

Explanation:

Hello there!

In this case, according to the described scenario, it is possible to realize that the reaction between hydrochloric acid and calcium hydroxide is:

2HCl+Ca(OH)_2\rightarrow CaCl_2+2H_2O

Whereas there is a 2:1 mole ratio of the acid to the base. In such a way, with the given masses, we can compute how much calcium chloride product is produced due to the chemical reaction via stoichiometry:

m_{CaCl_2}^{by HCl}=10.0gHCl*\frac{1molHCl}{36.46gHCl}*\frac{1molCaCl_2}{2molHCl}  *\frac{110.98gCaCl_2}{1molCaCl_2} =15.2gCaCl_2\\\\m_{CaCl_2}^{by Ca(OH)_2}=10.5gHCl*\frac{1molCa(OH)_2}{74.09gCa(OH)_2}*\frac{1molCaCl_2}{1molCa(OH)_2}  *\frac{110.98gCaCl_2}{1molCaCl_2} =15.7gCaCl_2

Whereas we infer that the correct amount is 15.2 g since HCl is the limiting reactant as it produces the fewest grams of the desired product. Consequently, the calcium hydroxide is the excess reactant here.

Regards!

Which component of delegation is the ability to perform duties in a specific role?
Nat2105 [25]

The component of delegation which speaks to the ability to perform a specific task is: Authority.

<h3>What is delegated Authority?</h3>

The division of work and assignment of decision-making authority to a person who answers to a leader or management is referred to as delegation of authority.

It is an organizational technique in which a management assigns each employee a portion of their own workload.

<h3>What is the difference between delegated authority and responsibility?</h3>

While the superior may transfer power to followers, responsibility is taken, or it is built into the duty that was given to the subordinate.

While responsibility calls for the capacity for compliance or obedience, the capacity to obey directions, authority requires the capacity to issue orders and instructions hence - responsibility.
