Answer:vv

Explanation:
The expression for the deBroglie wavelength is:
Where,
is the deBroglie wavelength
h is Plank's constant having value
m is the mass of =
v is the speed.
Wavelength = 5400 Å = 
Applying in the equation as:-


Answer:
Volume in L = 0.50 L
Explanation:
Given data:
Molarity of solution = 0.1850 M
Mass of BaCl₂ = 19.30 g
Volume of solution = ?
Solution:
First of all we will calculate the number of moles of solute:
Number of moles = mass/molar mass
Molar mass of BaCl₂ = 208.23 g/mol
Number of moles = 19.30 g / 208.23 g/mol
Number of moles = 0.093 mol
Volume of solution:
Molarity = number of moles of solute / volume of solution in L
0.1850 M = 0.093 mol / Volume in L
Volume in L = 0.093 mol / 0.1850 M (M= mol/L)
Volume in L = 0.50 L
Answer:
Sulfur
Explanation:
I'm sorry I was too late!
If there is an excess of a substance in a reaction, then there is more than enough to complete the reaction. This means that, because we have a specific amount of sulfur, it has to be the limiting reagent.
