False. gases have to greatest freedom of motion
The water cycle regardless if it is in a lake, our bodies, food, or underground.
Answer:
True
Explanation:
If a question cannot be tested and observed, it cannot simply be answered by science.
Science works with observable and testable ideas and not on metaphysics.
- Science presents a methodical approach into investigating phenomenon and answering likely questions in a logical manner.
- The body of facts and data gathered through observations and tests are used to ramify the conclusion of a scientific study.
- Without such, it is impossible to do the work of science.
Answer:
d. 127 g/mol.
Explanation:
Hello!
In this case, since we have the amount of molecules of this this compound, we are able to compute the moles out there by using the Avogadro's number:
![mol=7.02x10^{23}molec*\frac{1mol}{6.022x10^{23}molec}=1.17mol](https://tex.z-dn.net/?f=mol%3D7.02x10%5E%7B23%7Dmolec%2A%5Cfrac%7B1mol%7D%7B6.022x10%5E%7B23%7Dmolec%7D%3D1.17mol)
Which correspond to the moles of X2. Then, by using the mass we are able to compute the molar mass of X2:
![MM=\frac{296g}{1.17mol}\\\\MM=254g/mol](https://tex.z-dn.net/?f=MM%3D%5Cfrac%7B296g%7D%7B1.17mol%7D%5C%5C%5C%5CMM%3D254g%2Fmol)
It means that the atomic mass of X halves the molar mass of X2, which is then d. 127 g/mol.
Best regards!
