A. A group of related objects that do not send out or receive feedback and cannot modify themselves

Explanation:

An open-loop system is a a group of related objects or systems that cannot send out or receive feedback and modify themselves.

It is a non-feedback system.
In this system, the output control system has no effect on whatever input that is fed into the system.
Output and input in such systems are independent of one another.
The input and output has no control whatever on each other.

A 7.2 L balloon at 2 atm of pressure has its pressure reduced to 0.5 atm. What is the new size of the balloon, in liters?

alexgriva [62]

Explanation:

using Boyles law: which shows the relationship between pressure and volume, when temperature Is kept constant

P1V1 = P2V2

2 x 7.2 = 0.5 x V2

14.4 = 0.5 x V2

V2 = 14.4/0.5 = 28.8 L

Hence the new size of the balloon in litres is 28.8

Determine the theoretical maximum moles of ethyl acetate, , that could be produced in this experiment. The reactant, acetic acid

kherson [118]

Answer:

0.1832 moles of ethyl acetate ( $C_{4}H_{8}O_{2}$ )

Explanation:

1. Find the balanced chemical equation:

In the production of ethyl acetate, the acetic acid $CH_{3}COOH$ reacts with ethanol to produce ethyl acetate $C_{4}H_{8}O_{2}$ and water, that is:

$CH_{3}COOH+C_{2}H_{5}OH=C_{4}H_{8}O_{2}+H_{2}O$

2. Find the theoretical maximum moles of ethyl acetate $C_{4}H_{8}O_{2}$ :

As the problem says that the acetic acid $CH_{3}COOH$ is the limiting reagent, use stoichiometry to find the moles of ethyl acetate produced:

$11gCH_{3}COOH*\frac{1molCH_{3}COOH}{60.05gCH_{3}COOH}*\frac{1molC_{4}H_{8}O_{2}}{1molCH_{3}COOH}=0.1832molesC_{4}H_{8}O_{2}$

Alcoholic fermentation produces ethyl alcohol. This process also__

katrin [286]

Also known as ethanol fermentation, the process converts sugars such as glucose into cellular energy, which leaves bi-products of ethyl alcohol and carbon dioxide.

Hope this helps, let me know is this wasn't what you were looking for.
