Answer:
Explanation:
Hello,
In this case, given the described concept regarding the Avogadro's number, we can easily notice that 27.0 g of aluminium foil has 6.022x10²³ atoms as shown below based on the mass-mole-particles relationship:
Notice this is backed up by the fact that aluminium molar mass if 27.0 g/mol.
Best regards.
Answer:
C
Explanation
His greatest contribution is the atomic model
Answer:
red car will travel a much farther distance and at a faster speed as opposed to the blue car
Explanation:
Based on the information provided within the question Jenna can expect to observe that the red car will travel a much farther distance and at a faster speed as opposed to the blue car which will travel a shorter distance and at a lower speed. This is mainly because Jenna is applying an increased amount of force on the red car thus creating more acceleration and ultimately increasing the distance.
Use the Nernst equation which is:
E = E° - (RT/nF)*Ln Q
Where:
E the cell voltage in V,
R the gas constant 8.314 J/K•mol,
T the room temperature normally taken 298.15K, n=3 in this case,
F the Faraday constant 96485C,
Ln is the operation of natural logarithm, and: Q = [Cl-]^3*[Al3+]
Plugging in our values, will give us:
E = 1.88-(8.314*298.15/(3*96485))*Ln(0.010^3...)
= 2.01 (V)
The environmental change that occurs faster is definitely volcanic eruption. It may happen in an instant and destroy everything in its way, whereas the process of regrowth of forest after volcanic eruption is a slow one.
