The pressure of the compressed tank that was initially filled with hydrogen gas and has a pressure of 100kPa is pressure in the 250mL tank increases.
<h3>What is Boyle's law?</h3>
Boyle's law states that the observation that the pressure of an ideal gas is inversely proportional to its volume at constant temperature.
According to this question, a 1 L compressed tank is filled with hydrogen gas and has a pressure of 100kPa.
If all of the hydrogen gas is removed from the tank and pumped into a 250mL tank, which is smaller in volume, the pressure in the 250mL tank increases.

Answer:
<h2>Sodium Sulfide</h2>
Explanation:
Na2s means two sodium atoms and 1 sulfur atom. Sodium Sulfide is the answer. There isn't really a way to explain further.

Answer:
Explanation:
a self-contained convective zone in a fluid in which upward motion of warmer fluid in the center is balanced by downward motion of cooler fluid at the periphery.
The question is incomplete, the complete question is;
In the 1800s, a popular belief known as vitalism stated that life processes could not be explained by the laws of physics and chemistry,and were instead dictated by an independent life force. Which discovery most likely caused scientists to revise this hypothesis regarding the origin of life on Earth?
a. that inorganic compounds existed within live organisms
b. that organic compounds could be synthesized in a laboratory
c. that RNA could serve as a template to synthesize DNA
d. that self-replicating molecules existed inside cells
Answer:
b. that organic compounds could be synthesized in a laboratory
Explanation:
Vitalism is the belief that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things"(wikipedia).
This theory held that the molecules involved in life processes could not be synthesized in the laboratory.
All these were upturned after Fredrich Whöler's synthesis of urea in 1828. He was able to show that molecules involved in life process can also be synthesized in the laboratory. This gave rise to modern synthetic organic chemistry.
2. 3H2 + N2 means you have 6 Hs and 2 Ns. NH3 has one N and 3 Hs, so you need 2 NH3s in order to have the 2 and 6 of each that you need on both sides of the reaction.
