How does the chemical equation 2H2 plus O2 equals 2H2O demonstrate the law of conservation of mass and energy?
Elemental matter can be neither created or destroyed. The some number of atoms you started with an the left side of the equation is the same number you finish with on the right side of the equation.
What is the word equation for iron plus chlorine equals Iron chloride?
Iron plus chlorine equals Iron chloride is the word equation.
Determine the end value of n in a hydrogen atom transition if the electron starts in n equals 4 and the atom emits a photon of light with a wavelength of 486nm?
The wavelength of light emitted during a transition can be related to the energy levels involved using the Rydberg formula. Rearranging the formula for the final energy level, we find that the end value of n is 2 in this case. This means the electron transitions from the n=4 to the n=2 energy level in the hydrogen atom.
The equation E equals mc2 relates energy and?
*E = mc^2 'E' is the Energy 'm' is the mass ( kg) 'c' is the speed of light in a vacuum ( 3.8 x 10^8 m/s) 'c^2' is the speed of light squared. Hence E = kgm^2/s^2 , which are named 'Joules'. It is the Einsteinian equation , that if a mass looses mass, then the difference in mass is the energy released. NB It is very similar to the Kinetic Energy (K.E.) equation, which is K.E. = 0.5massvelocity^2.
What is the ionic equation of cacl2 plus na2s equals cas plus nacl?
The balanced molecular equation is CaCl2 + Na2S -> CaS + 2NaCl. To write the ionic equation, we need to break down the reactants and products into their respective ions. This results in the ionic equation: Ca2+ + 2Cl- + 2Na+ + S2- -> CaS + 2Na+ + 2Cl-. Cross out spectator ions that appear on both sides of the equation to obtain the net ionic equation: Ca2+ + S2- -> CaS.
What is the equation velocity equals wavelength x frequency called?
The equation velocity equals wavelength multiplied by frequency is called the wave equation. It describes the relationship between the speed of a wave, its wavelength, and its frequency.
What is the equation showing the relationship between the frequency (v) and wavelength (λ) of?
Frequency divided by 300 equals Wavelength
What equation can be used to show why a microwave has high energy?
Energy of microwaves is related to wavelength (lambda) and the speed of light (C). Energy equals Planck's Constant (6.6x10^34 Joules*second) multiplied by the speed of light (3.0X10^8 meters/second) divided by wavelength.
What wavelength would equal 5 joules?
The energy of a photon is given by E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength. To find the wavelength for 5 joules, you would rearrange the equation to solve for λ. Given the values for h and c, you can then calculate the wavelength.
Relativity theory equals e equals mc2?
Yes. It is Einstein's celebrated equation, E=mc2. It means "energy equals mass times the speed of light squared." It tells how to convert mass into energy. Einstein showed through this that mass and energy can be changed into each other.
What happens to the wavelength of a wave when the energy is increased?
If you are talking about an electromagnetic wave; energy is proportional to frequency (E=hf), and frequency is inversely proportional to wavelength (wavelength equals velocity divided by frequency). So when the wavelength is increased, the energy is decreased.
Why is a shorter wavelength of light emitted when an electron falls from n equals 4 to n equals 1 than when an electron falls from n equals 2 to n equals 1?
Shorter wavelength = more energy. The farther the electron falls, the more energy that will be emitted.
Examples of the equation velocity equals frequency wavelength?
Any wave. Of you have a wave (light, water etc.), it will have a frequency and a wavelength. Multiply these and you get the speed at which the wave is moving.
Which kind of energy is described by the equation E equals mc2?
Mass Energy.
What multiplied it by frequency equals wave Speed?
Wave speed is equal to the product of wavelength and frequency in a wave. This relationship is described by the equation: wave speed = wavelength x frequency.
How do you convert r equals 2sinX into rectangular form?
You also need an equation for y in order to convert to rectangular form.
How do matter and energy interact?
Matter and energy can convert into each other according to Einstein's famous equation, E = mc^2. This means that matter can be converted into energy and vice versa. For example, in nuclear reactions, some of the mass of the nucleons is converted into energy.
