Answer:
He would travel 3 kilometers.
Explanation:
Since he had already covered 1.5 kilometers in the time of 1 hour that means if he jogged for 1 more hour assuming he is going at the same pace he would've jogged 1.5 kilometers again and when you add that to the 1.5 kilometers he started with it would add up to 3 kilometers.
Answer: 100.3 mmHg
Explanation:
Given that:
Volume of nitrogen gas V = 4.200 L
Temperature T = 21°C
Convert Celsius to Kelvin
(21°C + 273 = 294K)
Pressure P = ?
Number of moles of gas = 0.02300
Molar gas constant R is a constant with a value of 0.0821 atm L K-1 mol-1
Then, apply ideal gas equation
pV = nRT
p x 4.200L = 0.02300 moles x (0.0821 atm L K-1 mol-1 x 294K)
p x 4.200L = 0.555 atm L
p = 0.555 atm L / 4.200L
p = 0.132 atm
Now, convert pressure in atm to mmHg
If 1 atm = 760 mmHg
0.132 atm = (0.132 x 760) = 100.3 mmHg
Thus, 100.3 mmHg of pressure is required
Observation, hypothesis, experiment is the correct answer
Answer:
Hey there!
A MSDS is a Material Safety Data Sheet, and can be used to provide detailed and comprehensive information about the hazards of a certain product, such as medicine or chemicals.
Let me know if this helps :)
a, c, and d are all chemical properties because they give information about how a substance will behave in the given reaction, and can’t be found without the substance undergoing some sort of chemical reaction. b, on the other hand, is a physical property—it can be determined without changing the substance’s chemical composition.
