Mass can be conveted into energy by a nuclear reaction. The ammount of energy converted can be calculated by E=mc^2. So for every gram that is lost 9,000,000,000,000,000 J of energy will be released. That is enough to power a 100 Watt light bulb for 3 million years. That's a lot of energy.
Every type of reactions involve the law of conservation of mass, but you might refere to a chemical reaction, the law states that no matter can be created or destroyed, meaning that if for example: 100 million atoms of magnesium react with 300 million atoms of oxygen, the result yould contain 100 millionatoms of magnesium with 300, 000 atoms of oxygen, no more no less.

The mass is not lost but transformed in energy.
No. Nor can you convert mass into energy. In any reaction - including nuclear reactions - both the amount of mass and the amount of energy remain the same, before and after the reaction. For example, the energy that escapes from a nuclear reaction also has a corresponding mass. On the other hand, the energy existed before the reaction as well, in the form of (nuclear) potential energy.
Once the mass is known, so is the energy, and vice versa. So yes it can be transformed both ways.
The energy in the wind is kinetic, it is due to a mass of air moving at a certain speed. Wind energy is transformed into mechanical energy through the blades of the wind turbine, and the mechanical energy is then transformed into electrical energy in a generator driven by the blade axis.
It is transformed in heat due to the friction.
It is often stated that mass is transformed to energy. This is wrong, since both mass and energy are conserved in a chemical reaction - or in a nuclear reaction. The Wikipedia article on "binding energy" clarifies this.
The mass is not lost but transformed in energy.
The first law of thermodynamics states that energy can be transformed, but not created nor destroyed. In a nuclear reaction, mass is transformed into energy.
Because of a fusion reaction in which hydrogen is transformed into helium. The mass that goes missing during this process is transformed into energy by Einstein's E equals M C squared law of relativity.
Any reaction that consumes energy, or has a positive delta(H), is called an endothermic reaction.
No. Nor can you convert mass into energy. In any reaction - including nuclear reactions - both the amount of mass and the amount of energy remain the same, before and after the reaction. For example, the energy that escapes from a nuclear reaction also has a corresponding mass. On the other hand, the energy existed before the reaction as well, in the form of (nuclear) potential energy.
Once the mass is known, so is the energy, and vice versa. So yes it can be transformed both ways.
A part of mass is transformed in energy.
The energy in the wind is kinetic, it is due to a mass of air moving at a certain speed. Wind energy is transformed into mechanical energy through the blades of the wind turbine, and the mechanical energy is then transformed into electrical energy in a generator driven by the blade axis.
the energy produced by the reaction.
It is transformed in heat due to the friction.
In any reaction, or process, both the amount of mass and the amount of energy remain constant. You might say that mass has energy, and energy has mass. Any mass or energy "created" during a reaction was already present previously.
