Hello there!
2. In this case, we can evidence the problem by which volume and temperature are involved, so the Charles' law is applied to:
Thus, considering the temperatures in kelvins and solving for the final volume, V2, we obtain:
Therefore, we plug in the given data to obtain:
3. In this case, it is possible to realize that the 3.7 moles of neon gas are at 273 K and 1 atm according to the STP conditions; in such a way, considering the ideal gas law (PV=nRT), we can solve for the volume as shown below:
Therefore, we plug in the data to obtain:
Best regards!
<h3>Answer:</h3>
Heterogeneous mixture
<h3>Explanation:</h3>
The easiest way of defining Heterogeneous mixture is that it is mixture in which the composition of components is not uniform. Also, the substances present in this mixture are visible to naked eye. In fact, the size of solutes in heterogeneous mixture is greater as compared to that the sizes of solutes in homogeneous solutions. hence in salad dressing the oil, vinegar and spices are all visible and can easily be seen by naked eye.
Answer:
B
Explanation:
Solar power takes in light and turns it into a usable energy. if used in a vehicle that would take light energy and transform it into mechanical energy.
The component in the mixture with the lowest density would be the component floating on the top of the mixture, i.e. the lightest in weight. Therefore, it would be the sawdust.
