The threshold frequency of Cesium is 5.2 x 10^14 Hz.
To find the frequency of yellow light, we use the equation:
speed of light = wavelength x frequency
3 x 10^8 = 5.8 x 10^-17 x frequency
frequency = 5.17 x 10^24
This is higher than the threshold frequency of Cesium, thus, electrons will be emitted.
Answer:
Orbitals give a probability map of where it is likely to find an electron in an atom.
Explanation:
Wave mechanical model of the atom suggests that an atom contains a nucleus which has positively charged protons and neutral neutrons.
The outer part of the atom is mostly empty.
The negatively charged electrons are located in outer orbitals.
The true statement is :
Orbitals give a probability map of where it is likely to find an electron in an atom.
Answer:
Las sales ideales para la saponificacion es la combinacion de grasas complejas con muchas cadenas de trigliceridos y de la soda caustia.
Explanation:
Un ejemplo de estos son la grasa vacuna o la aceite de cocina de consumo tradicional y la soda caustica que es el hidroxido de sodio.
Juntos estos dos productos forman el proceso de saponificacion.
Answer:
Answer: approximately 60g of c6H12O6
Explanation:
We have the balanced equation (without state symbols):
6H2O+6CO2→C6H12O6+6O2
So, we would need six moles of carbon dioxide to fully produce one mole of glucose.
Here, we got
88g of carbon dioxide, and we need to convert it into moles.
Carbon dioxide has a molar mass of
44g/mol
. So here, there exist
