3Ba + Au3(PO)2 =Ba3(PO)2 + 3Au
Answer:
c = 325.0 m/s.
Explanation:
Hello there!
In this case, since the frequency, velocity and wavelength are related via:
Whereas c is the velocity, lambda the wavelength and f the frequency. Thus, we plug in the given data to obtain:
Best regards!
Answer:
The unknown solution had the higher concentration.
Explanation:
When two solutions are separated by a semi-permeable membrane, depending on the concentration gradient between the two solutions, there is a tendency for water molecules to move across the semi-permeable in order to establish an equilibrium concentration between the two solutions. This movement of water molecules across a semi-permeable membrane in response to a concentration gradient is known as osmosis. In osmosis, water molecules moves from a region of lower solute concentration or higher water molecules concentration to a region of higher solute concentration or lower water molecules concentration until equilibrium concentration is attained.
Based on the observation that when the glucose solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level rises, it means that water molecules have passed from the glucose solution through the semipermeable membrane into the unknown solution. Therefore, the solution has a higher solute concentration than the glucose solution.
Answer:
You didnt give use the choices you have but I can try to help. Climate can change when it snows,rains,when it is sunny,or cloudy.
Explanation:
The rain allows the climate to cool down depending in the weather out. Same with cloudy weather. Snow can also cause temperature to drop down. When it is sunny, the climate in the sun will be warm, until getting in the shade and it gets cold again.
