Answer:
14.7 lbs
Explanation:
Air pressure is the weight of the air above us. It is approximately 14.7 pounds or lbs per square inch at sea level. It means that an air column weights 14.7 lbs, 1 square inch in diameter, reaching all the way up to the top of the atmosphere.
Because gravity treats all mass equally. It doesn't treat heavier objects with greater force. All objects experience the gravitational pull equally. Making the two different weights reach the ground together simultaneously despite their weight differences.
Answer:
Concentration of ethanol required = 48.476 M
Explanation:
Given that:
the absorption intensity = 1.00
Molarity of ethanol = 1M
NMR instrument used = 160 MHz
Temperature used = 300 K
The required concentration of ethanol can be determined as follows:
= 48.476 M
Information about how a chemical reacts under high pressure can be found in the "reactivity" section of a MSDS: True.
<h3>What is MSDS?</h3>
MSDS is an abbreviation for Material Safety Data Sheet and it can be defined as a text-based document which is designed and developed to provide more information with respect to the chemical and physical properties of an equipment, chemical compound, or substance, based on the following:
In this context, we can infer and logically deduce that it is true that the information about how a chemical react would under high pressure can be found in the "reactivity" section of a Material Safety Data Sheet (MSDS).
