A glow stick contains two chemicals and a suitable dye (sensitizer, or fluorophor). This creates an exothermic reaction. The chemicals inside the plastic tube are a mixture of the dye and diphenyl oxalate. The chemical in the glass vial is hydrogen peroxide.
Answer:
ions; when atom lose or gain electron
Explanation:
when an atom lose electron it becomes positive ion (cation) when an atom gain electron it becomes negative ion(anion)
isotope has same number of atomic number (proton) but different neutron number which affects mass number
Pounds of gold ore : 11,02311
<h3>Further explanation</h3>
Given
5 g of gold
0.1% gold by mass
Required
Pounds of gold ore
Solution
![\tt \%mass~gold=\dfrac{mass~gold}{mass~ore}\times 100\%](https://tex.z-dn.net/?f=%5Ctt%20%5C%25mass~gold%3D%5Cdfrac%7Bmass~gold%7D%7Bmass~ore%7D%5Ctimes%20100%5C%25)
For percent mass = 0.1%, than mass of gold ore :
![\tt 0.1\%=\dfrac{5~g}{mass~ore}\times 100\%\\\\mass~ore=\dfrac{5\times 100}{0.1}\\\\mass~ore=5000~g](https://tex.z-dn.net/?f=%5Ctt%200.1%5C%25%3D%5Cdfrac%7B5~g%7D%7Bmass~ore%7D%5Ctimes%20100%5C%25%5C%5C%5C%5Cmass~ore%3D%5Cdfrac%7B5%5Ctimes%20100%7D%7B0.1%7D%5C%5C%5C%5Cmass~ore%3D5000~g)
Conversion factor :
1 g = 0,00220462 pound, than for 5000 g = 11,02311 pounds
