Answer:
The symbol used to separate the product from each other or reactants from each other is 'plus' (+) .
Explanation:
In chemical equation the symbol used to separate the product from each other or reactants from each other is 'plus' (+) .
While the symbol used to separate the reactant and product from each other is '→'
For example:
Consider the following reaction.
2H₂ + O₂ → 2H₂O
Two moles of hydrogen react with one mole of oxygen to form two moles of water. The both reactant hydrogen and oxygen are separated by the + while reactant and products are separated by → .
Answer:
Light is made up of wavelengths of light, and each wavelength is a particular colour. The colour we see is a result of which wavelengths are reflected back to our eyes. The visible spectrum showing the wavelengths of each of the component colours. The spectrum ranges from dark red at 700 nm to violet at 400 nm.The 'colour' of an object is the wavelengths of light that it reflects. This is determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to complicated quantum laws.The reason that different waves of light appear to be different colors of light is because the color of a light wave depends on its wavelength. For example, the wavelength of blue light is about 450 nanometers, while the wavelength of red light is about 700 nanometers.
Explanation:
<span>While
treating food with gamma rays kills microorganism by damaging their DNA, the energy
of gamma rays rips off electrons from atoms hence ionizing them (causing free radicals).
However, gamma rays do not make the food atoms radioactive. The body has a natural
mechanism of riding the body of free radicals. However, large quantities of radicals in the body can cause
damage.</span>
The answer is b because the wind exerts a force on the kite
