The Pascal (symbol: Pa) is the SI derived unit of pressure. It is used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is defined as one Newton per square meter. It is named after the French polymath Blaise Pascal.
The Pascal (Pa) or kilo pascal (kPa) as a unit of pressure measurement is widely used throughout the world and has largely replaced the pounds per square inch.

Explanation:What is the demand factor for three commercial ranges?
Answer:
151.94 u
Explanation:
The atomic mass of Eu is the <em>weighted average</em> of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its <em>percent abundance</em>).
The atomic masses of Eu-151 and Eu-153 are 150.92 u and 152.92 u, respectively.
Set up a table for easy calculation.
0.4803 × 150.92 u = 72.472 u
0.5197 × 152.92 u = <u> 79.473 u
</u>
TOTAL = 151.94 u
I would say Na. Oxygen has 2 valence electrons and when reacting with other molecules, the ones with the fullest or emptiest shells will react the least. Both H2 and Na are in the Alkali Metals in the first row, but since H2 has 2 molecules, it would use more oxygen than Ana
I think eventually other organisms will die out as well because many herbivores feed on plants for survival, and many other animals feed on these herbivores for survival and so on (this causes a chain reaction because there is a lack of available food)<span />
