1 mole is equal to 6.0220 x 1023 atoms of any element.
1. Both evaporation and condensation are steps in the water cycle.
2. Both are affected by atmospheric conditions.
Let me know how you did, good luck! :D
Answer what are you asking
Explanation:
Keq= (products)/ (reactants)
Keq= ( [NO]^2 x [Cl2]) / ( [NOCl]^2)
Keq= ( (0.02)^2 x (0.01) ) / (0.5)^2= 1.6 x 10-5
Answer:
295 mL
Explanation:
Given data:
Volume needed = ?
Molarity of solution = 0.193 M
Mass of salt = 7.90 g
Solution:
Molarity = number of moles of solute / volume in L
Number of moles of salt = mass/molar mass
Number of moles of salt = 7.90 g/ 138.205 g/mol
Number of moles = 0.057 mol
Volume needed:
Molarity = number of moles / volume in L
0.193 M = 0.057 mol / volume in L
Volume in L = 0.057 mol / 0.193 M
Volume in L = 0.295 L
L into mL
0.295 L × 1000 mL/1L
295 mL
