The purpose of an universal indicator is to test wether a solution is acid or if its a base. It changes colors according to the PH's. It helps a lot in the indication of a chemical reaction because it can say if <span>each component loses or gains protons depending upon the acidity or basicity of the solution being tested.An universal indicator can say if a determined solution proves to be endothermic or exothermic. If the solution is not tested as acid or base then we cannot knwo if there will be an endothermic reaction or an exhotermic one</span>
Answer:
the ratio of the universe's helium to hydrogen by mass is 2:5 approximately.
Explanation:
To solve this question, we assign arbitrary values to these elements in tandem to the data given in the question.
nH, Number of Hydrogen atoms = X = 100
nHe, Number of Helium atoms = 0.1X = Y = 10
From the data given, by mass:
if the mass of Hydrogen atom = 1g = 100g
therefore, the mass of a Helium atom = 4g (1*4) = 40g
Mass ratio of Helium to Hydrogen = 40:100 = 4:10 = 2:5 approximately
