The answer is B. Jupiter is a gas giant; Venus is terrestrial.
It means 3p (p being your variable) to the third power, or cubed
Answer:
2 molecules of water represents 3.32 x 10^-24 moles of water.
Explanation:
To find the solution to this problem, you have to use the concept of Avogadro´s number, that is in 1 mol of any element o compound there are 6.022 x 10^23 molecules. Then,
1 mol H2O ------------- 6.022 x 10^23 molecules
x= 3.32 x 10^-24 ---- 2 molecules.
2 molecules of water represents 3.32 x 10^-24 moles of water.
A law is statement about an observed concept. A theory involves the explanation of scientific concepts or principles. A hypothesis is the predicted explanation about some concepts that has to be tested in order to prove it to be right. An observation is the observing the results of a scientific experiment carried out to test an hypothesis.
Here the given statement 'A chemist mixes sodium with water and witnesses a violent reaction between the metal and water,' can be classified as an observation as it explains what the chemists observes as a result of his chemical experiment or test..
Answer:
Boyle's law: A) Pressure and volume.
Charles's law: B) Temperature and volume.
Gay-Lussac's law: C) Pressure and temperature.
Explanation:
Hello,
In this case, since Boyle's law study the relationship between pressure and volume at constant temperature as an inversely proportional one, we have:
Boyle's law: A) Pressure and volume.
Next, since the Charles' law study the relationship between the volume and the temperature at constant pressure as a directly proportional one, we have:
Charles's law: B) Temperature and volume.
Then, since the Gay-Lussac's law study the relationship between the pressure and the temperature at constant volume as a directly proportional one as well, we have:
Gay-Lussac's law: C) Pressure and temperature.
Best regards.
