Answer : The correct option is, Light absorption
Explanation :
Microspectrophotometer : It is a type of instrument that measures the spectra of the microscopic sample by using the different wavelengths of an electromagnetic radiation.
It is designed to measure the the spectrum of the microscopic sample. It is also measure the transmittance, absorbance, polarization and fluorescence of the microscopic sample.
From the given options, the option light absorption is the correct option.
Hence, a microspectrophotometer measures the light absorption.
Au (Gold) is an atomic element
Answer:
addition of aqueous hydrochloric acid
Explanation:
The solubility of copper (ll) hydroxide in water is negligible. This implies that the substance is only slightly soluble in water.
However, the addition of aqueous hydrochloric acid leads to the following reaction;
Cu(OH)2 + 2HCl ---------> CuCl2 + 2H2O
Copper II chloride is soluble in water hence the crystals dissolve when stirred. and the molar solubility increases.
The answer is C. 4.6 billion years. Hoped I helped. :)
150 grams of water because if 225 grams of propane are burned with 125 grams of oxyegen then there will be 150 grams of water
