The correct answer is C. Lemon juice

Explanation:

The acidity of a solution depends mainly on their ph, in this way a pH from 0 to 6 indicates a substance is acid, a pH of 7 shows the substance is neutral and a higher pH shows a substance is a base which is the opposite to acids as bases accept hydrogen ions if dissolved while acids release them. Also, the lower the pH the most acidic a solution is. In this way, lemon juice has a pH of 2 and therefore is the most acidic in comparison to tomato juice with a pH of 4, water with a pH of 7 (neutral pH) and sodium hydroxide with a pH of 12 (base).

Atelectasis is caused by occupational exposure to coal dust.<br> a. true<br> b. false
Irina18 [472]
The statement is true. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may effect part or all of a lung. An airway blockage also can cause Atelectasis. A blockage may be due to a foreign object, a mucus plug, lung cancer, or a poorly placed breathing tube from a ventilator. When a blockage occurs, the air that's already in the air sacs is absorbed into the bloodstream.
