True, nuclear fusion is a reaction in which multiple atoms come in contact to form new atom and subatomic particles. in a nuclear fusion, some of the mass is lost which defies the law of conservation of mass, but according to scientist the lost in mass is manifested in the production of huge amount of energy,
Answer:
Reactants are transformed into products
Explanation:
Chemical reactions are happening everywhere, it may be represented by the following equation:
A(aq) + B(s) ⇒ C(g) + D(l)
The left side represent the reactants that interact to get the products.
In the parenthetycal note is the state of the compound, in this case, aquose solution (aq), solid (s), gas (g), liquid (l)
Answer:
Coal contains chemical potential energy
Explanation:
Chemical species are known to contain chemical energy. Chemical energy is contained in chemical bonds in a chemical substance.
Since energy can neither be created nor destroyed, energy contained in chemical bonds can be transformed from one form to another. Coal contains chemical energy.
One of the ways of generating electricity is the combination of fossil fuels. This involves the conversion of chemical energy to heat energy. The steam produced is used to turn a turbine. The turning off the turbine implies a conversion of heat to mechanical energy. The turning of the turbine now produces electrical energy.
The units on the ruler are inches, centimeters, and millimeters. Nanometers (nm) is equivalent to 10^-9 m. Each graduation on the ruler represents 0.1 millimeters or 0.01 centimeters. The other side also has a graduation of 0.1 inch. The function of the ruler depends on how you use it.
Answer:
Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. ... Renewable resources are replenished naturally and over relatively short periods of time. The five major renewable energy resources are solar, wind, water (hydro), biomass, and geothermal.
Explanation:
