Answer:
The acetylene must be fill at 315 atm.
Explanation:
Given data:
Pressure of oxygen =P₁= 135 atm
Volume of oxygen = V₁=7.00 L
Volume of acetylene = V₂=3.00 L
Pressure of acetylene =P₂= ?
Solution:
According to Boyle's law
P₁V₁ = P₂V₂
P₂ = P₁V₁/V₂
P₂ = 135 atm × 7.0 L / 3.00 L
P₂ = 945 atm. L/ 3.00 L
P₂ = 315 atm
The acetylene must be fill at 315 atm.
You didn't give an answer choice there, but I believe the answer is Hydrobromic Acid. Strong Acids are considered to ionize.
Answer:
The correct answer is 783 kg.
Explanation:
To solve this problem, we first must simply add all three values together. We can perform this operation because all three values have the same units of kilograms.
When we add, we get:
258.3 + 271.23 + 253 = 782.53 kg
However, this answer does not have the correct number of significant digits. When adding and subtracting values, we round our final answer to the least amount of decimal places of the numbers we were adding. In this case, that is 0 decimal places, because 253 doesn’t have a decimal place.
Therefore, we should round 782.53 to the ones place. Since the next number is a 5, we round up.
This gives us 783 kg, which is our final answer.
Hope this helps!
Explanation:
It is known that in 1 mole there are
atoms or molecules.
It is given that there are
carbon molecules. Therefore, calculate the moles as follows.
Number of moles = 
= 1.196 mol
Thus, we can conclude that there are 1.196 mol in
carbon molecules.
Answer:
if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That's because Mercury weighs less than Earth, and therefore its gravity would pull less on your body. If, on the other hand, you were on heavy Jupiter, you would weigh a whopping 253 pounds!
