Answer:
What is energy transformation? One type of energy can change into another type of energy. Energy transformation means the changing of energy from one type to another, e.g. from kinetic energy to electrical energy, or from potential energy to kinetic energy.
Explanation:
Answer:
Explanation:
You have the equation. Now change the 3.4 g H2 to moles. moles = grams/molar mass
<em>3.4 g/2.016 = 1.686 moles.</em>
Now using the coefficients in the balanced equation, convert moles H2O2 to moles H2O.
1.686 moles H2 x (2 moles H2O/2 moles H2O2) = 1.686 x (2/2) = 1.686 x (1/1) = 1.686 moles H2O.
Now you know that 1 mole of water is composed of 6.022 x 10^23 molecules. So
1.686 moles H2O x (6.022 x 10^23 molecules H2O/1 mole H2O) = ?? molecules.
The given statement is false.
The electrons have both wave and particles like properties. It was postulated by De Broglie that electrons have wave nature and suggested that all the matter exhibit wave characteristics. This concept is called the De Broglie hypothesis.
Like all the elementary particles, the electrons possess the characteristics of both waves and particles, in the sense that they can collide with other particles and be diffracted like light.
Two different atoms have nine protons each and the same mass. However, one is neutral while the other has a negative charge then the atomic structure of the both atom are of same element but one of them is electrically neutral and other has a stable electronic configuration
An atom is said to be neutral because it has an equal number of electron and proton in it and if two different atom have nine proton each and same the mass but one is neutral while the other has a negative charge and the mass of an atom is determined by the number of proton and neutron is present in its nucleus and since both the given atom have 9 proton and the same mass and they must also have the same number of neutron
This implies both the atom have the same nucleus but different charges so it can be concluded that they both the atom of the same element but one of them is electrically neutral and other has stable electronic configuration
