Answer:
Isotopes, protons, netrons
Explanation:
Solute is something that is being dissolved { ex : sugar , salt}
Solvent is something that has ability to dissolve things { ex : water}
False because the solvent is present in larger amounts...
Answer: The values can be converted from one unit to other unit still keeping the meaning same. We use the number 273 (273.15 exactly) to convert from Celsius to Kelvin and vice versa. . ... Kelvin temperature scale: In Kelvin temperature scale, the zero point is shifted from freezing point of water to the absolute zero point.
Explanation:
Basically the answer
Hey there !
Answer BChemical properties are
characteristic behaviors of a substance when it is found in the presence of
another substance. To investigate chemical properties we will have to carry out
chemical transformations (performing chemical tests) and it is generally not
possible to recover the sample used (because it suffers changes giving rise to
other substances).

Answer:700 nm corresponded to light in the red range and 450 nm corresponded to light in the blue range.
Explanation:The wavelengths of the visible spectrum are usually between 400 nm and 700 nmn with the the rays of red light having a longer wavelength, and blue light rays having shorter wavelengths. The red light has a low frequency of about 405–480 THz and , blue light has a higher frequency in the range of 620–680 THz. This is due to the inverse relationship between wavelength and frequency which also occurs betwwn wavelength and energy of light rays with the red light having less photon energy of about 1.65–2.00 eV and the blue light with high energy photons of about 2.64–2.75 eV.
Red light can be employed in the photosynthesis in plants as it helps in formation of flowers and the production of fruits. Blue light also is important in the production of chlorophyll and can cause a healthy and strong stem and leaves in excess exposure.
