The correct answer is 92. <span> uranium atom has 92 protons and 92 electrons. hope this helped, have an amazing day :)</span>
Explanation:
conduction involves the transfer of molecules due to the movement of particles
Explanation:
the stationary phase in TLC is a <u>silica gel coated metal plate or paper</u>.
The<u> individual</u> component of the mixure will travel a greater distance up the plate, resulting in a <u>Rf</u> value for the component.
the <u>p-Xylene spot </u> will travel a greater distance as it is the <u>lighter</u> component
Bromobenzene will travel least as it is the <u>heavier</u> component.
thin layer chromatography (TLC) is a type of chromatographic seperation technique that is based on the molecular size of components. the Rf value is the distance covered by the component relative to that travelled by the solvent which is the mobile phase
Answer:
All the amounts of reactants and products are:
KBr
11.0g (given)
0.0924 mol
Cl₂
0.0462 mol
3.28g
KCl
0.0924 mol
6.89 g
Br₂
0.0462 mol
7.39 g
Explanation:
<u>1. Balanced chemical equation (given)</u>

<u>2. Mole ratios</u>



<u />
<u>3. Molar masses</u>
- Molar mass Cl₂: 70.906g/mol
- Molar mass KBr: 119.002 g/mol
- Molar mass KCl: 74.5513 g/mol
- Molar mass KBr: 159.808 g/mol
<u>4. Convert 11 grams of potassium bromide to moles:</u>
- #moles = mass in grams / molar mass
- #mol KBr = 11g / 119.002g/mol = 0.092435mol KBr
<u>5. Use the mole ratios to find the amounts of Cl₂, KCl, and Br₂</u>
a) Cl₂


b) KCl


c) Br₂


The final calculations are rounded to 3 sginificant figures.
