Is xenon in the n equals 5 energy level?
No, xenon does not have electrons in the n equals 5 energy level in its ground state. In its ground state, xenon's electron configuration fills up to the n equals 4 energy level before moving on to higher energy levels for excited states or ionized forms.
How long does it take for radiation from a cesium-133 atom to complete 4.5 million cycles?
A cesium-133 atom makes 9,192,631,770 cycles per second. Divide it by 4.5 million: 9,192,631,770 / 4,500,000 = 2042.807 Divide 1 second by 2042.807 and the result is 4.895 *10^-4 seconds. If you multiply it by 10^6 you get microseconds: 4.895*10^-4 * 10^6 microseconds/second and that equals 489.5 microseconds.
The amount of energy in the bonds of the reactants plus any energy absorbed equals the amount of energy in the bonds of the products plus any energy .?
Released
What is the molecular formula of a compound containing 89 percent cesium Cs and 11 percent oxygen O with a molar mass equals 298 gmol?
The compound contains 1 cesium atom (Cs) and 1 oxygen atom (O). The molar mass of cesium is about 133.0 g/mol and oxygen is about 16.0 g/mol. Calculating the molar mass of Cs: (0.89 * 133.0 g/mol) = 118.37 g/mol Calculating the molar mass of O: (0.11 * 16.0 g/mol) = 1.76 g/mol Adding the molar masses together: 118.37 g/mol + 1.76 g/mol = 120.13 g/mol Thus, the molecular formula is CsO.
The amount of energy in the bonds of the reactants plus any energy absorbed equals the amount of energy in the bonds of the products plus any energy?
released as heat. This is described by the principle of conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted from one form to another during a chemical reaction.
What is released as one form of energy changes to another form?
Energy. Given that energy can be neither created nor destroyed, the total energy output equals that input, and in a system the ratio of that output energy desired to the total input gives the efficiency.
Basic measurement of time?
the basic measurement of time is the second, 1 second equals 9,192,631,770 periods of the radiation of cesium 133 ions
When compared with an electron for which n equals 2 an electron for which n equals 4 has more?
Energy
Total energy input equals equals the useful energy output plus?
Efficiency = ( useful energy output / total energy input ) x 100
Which level in energy has the less energy n equals 4 n equals 3 n equals 2 n equals 1?
n=1 is the the lowest level there is.
What does potential energy plus gravitational energy equals?
Gravitational-potential energy.
What is kinetic energy plus potential?
It equals basic energy
What is the following types energy equals the total energy motion and position?
The type of energy that equals the total energy of an object's motion and position is mechanical energy. It is the sum of kinetic energy (energy due to motion) and potential energy (energy due to position or state).
Does the total mechanical energy of a system remain constant, even when the kinetic energy equals the potential energy?
Yes, the total mechanical energy of a system remains constant even when the kinetic energy equals the potential energy. This is known as the conservation of mechanical energy.
What does pe equals mgh stand for when you are talking about energy?
Potential Energy
E equals mc2 IF M equals 0?
zero mass = zero energy
What is the molecular formula of a compound containing 89 percent cesium Cs and 11 percent oxygen O with a molar mass equals 298 g per mol?
Cs2O2 APEX 2021
