Answer:
Heterogeneous
Explanation:
The catalyst, Pt, is not in the same phase as the reactants, i.e. it is solid, whilst the hydrogen peroxide is aqueous.
Answer:
v2 = 100 Ml OR 0.1 Liters
Explanation:
(400 Ml) (10 atm) = (v2) (40 atm)
4000 = 40v2
100 Ml = v2
Liters = ml / 1000
Liters = 100 / 1000
Liters = 0.1
Answer:
A = Molarity = 0.22 M
B = Molarity = 0.36 M
Explanation:
Given data:
For first solution:
number of moles = 0.550 mol
Volume of solution = 2.50 L
Molarity = ?
Molarity:
Formula:
Molarity = number of moles of solute / volume of solution in L.
Molarity = 0.550 mol / 2.50 L
Molarity = 0.22 M
For second solution:
Mass of NaCl = 15.7 g
Volume of solution = 709 mL or 709/1000 = 0.709 L
Molarity = ?
Solution:
Number of moles = mass / molar mass
Number of moles = 14.7 g/ 58.44 g/mol
Number of moles = 0.252 mol
Molarity:
Molarity = number of moles of solute / volume of solution in L.
Molarity = 0.252 mol / 0.709 L
Molarity = 0.36 M
