A conductor allows heat, light, sound, or an electric charge to run through it.
Answer:
43.75 ml
Explanation:
Given that the equation of the reaction is;
2HNO3(aq) + Ca(OH)2(aq) ---> Ca(NO3)2(aq) + 2 H20(l)
Concentration of acid CA= 0.05 M
Concentration of base CB = 0.02 M
Volume of acid VA = 35.00ml
Volume of base VB= ???
Number of moles of acid NA= 2
Number of moles of base NB=1
From
CAVA/CBVB= NA/NB
Making VB the subject of the formula;
VB= CAVANB/CBNA
VB= 0.05 × 35 × 1/ 0.02 × 2
VB=1.75 /0.04
VB= 43.75 ml
A platinum wire is dipped into a strontium nitrate solution. Then inserted into a burner flame, then the strontium atoms emit a characteristic red color. this is an example of how an element can be identified by its unique atomic emission spectrum.
<h3>What is atomic emission spectrum?</h3>
The goal of an atom's electron arrangement is to keep the energy of the atom as low as feasible. An atom's ground state has the lowest energy level of all the atoms. When the energy is applied to those atoms, the electrons take it in and go to a higher energy level. The electrons in atoms have quantized energy levels, which again means that they must transition from one level to another in discrete increments rather than constantly. An atom is said to be in an excited state when its potential energy exceeds that of the ground state. An excited atom is not a stable atom.
