Answer:
B) 1270 torr
Explanation:
Given data
- Initial volume (V₁): 5.00 L
- Initial pressure (P₁): 760 torr
- Final volume (V₂): 3.00 L
We can find the final pressure using Boyle's law.
P₁ × V₁ = P₂ × V₂
P₂ = P₁ × V₁/V₂
P₂ = 760 torr × 5.00 L/3.00 L
P₂ = 1.27 × 10³ torr = 1270 torr
The final pressure is 1270 torr.
It’s a chemical reaction I guess? Or maybe it hits the water and unlike a solid and it being a liquid it goes into the water causing it to spread or something like that.
Answer: The correct answer is option D.
Explanation: Super-giant stars are the stars which are greater than Sun. They have a mass hundred time greater than Sun and can be thousand times greater than Sun.
The masses of the stars are represented in Solar masses which is the mass of the Sun.
Mass of Betelgeuse = 20 Solar masses
Mass of Pollux = 1.7 Solar masses
Mass of Sirius = 2.02 Solar masses
Mass of Sun = 1 Solar mass.
As, the mass of Sun is the least from the given stars. Hence, it is least considered as a super-giant.
Answer:
- <u><em>0.80 mol Al</em></u>
Explanation:
<u>1) Word reaction:</u>
- Aluminum + ferrous oxide → aluminum oxide + iron
This is a single replacement reaction, in which aluminum, a more acitve metal than iron, replaces the iron in the ferrous oxide to form aluminum oxide and iron.
<u>2) Skeleton chemical equation:</u>
<u>3) Balanced chemical equation:</u>
Add the coeffcients to comply with the law of conservation of mass:
<u>4) Mole ratio of Al and FeO:</u>
<u>5) Set a proportion with the unkown and solve:</u>
- x / 1.2 mol FeO = 2 mol Al / 3 mol FeO
- x = 1.2 mol FeO × 2 mol Al / 3 mol FeO =<u> </u><u>0.80 mol Al ← answer</u>
Answer:
Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock. Movement is caused by shear stress sufficient to produce permanent deformation, but too small to produce shear failure. ... Continuous, where shear stress continuously exceeds the strength of the material.
