All of the following are benefits of automation except
1. it reduces costs
2. it improves precision
3. it helps eliminate human error
4. it increases the number of employees

Stoichiometry is the same regardless of which two elements are being examined
1. true
2. false

what problem does chlorofluorocarbon create
1. it causes lead poisoning
2. it causes great damage to the ozone layer
3. it leaks into food as it cools the air on refrigerators
4. it is responsible for most of the pollution created by automobiles

A closed loop system is more sophisticated than an open loop system
1. true
2. false

The answer to the first question is the 4th option. The answer to the second question is false. The answer to the third question is option 2. The answer to the Fourth question is true.

1. Automation can be described as the use of technology to carry out tasks done by humans.

Benefits:

lower costs
precision
elimination of human error

Automation does not increase number of employees

2. The answer to this question is false. Stoichiometry is not the same regardless of which two elements are examined. Stoichiometry tells us about how products and reactants are related in a chemical reaction.

3. The problem that Chlorofluorocarbon causes is the damage to the ozone layer. It causes a depletion of the protective ozone layers and exposes people to ultra violet radiations.

4. A closed loop system is more sophisticated than the open loop. The closed loop can self correct unlike the open loop.
