a. warm and rainy
Answer:
1.68 M
Explanation:
Molar mass (KNO3)= 101.1 g/mol
89g KNO3* 1mol/101.1 g = 89/101.1 mol
(89/101.1 mol)/0.525 L= 1.68 mol/L = 1.68 M
Answer:
3.04 atoms
Explanation:
because of the switzer theory
Answer is: <span>b) 9,042 L.
Ideal gas law: p</span>·V = n·R·T.
p is the pressure of the gas.
V is the volume of the gas.
n is amount of substance.
R is universal gas constant.
T is temperature.
T₁ = 15°C = 288 K.
V₁ = 10,5 L.
T₂ = -25°C = 248 K.
V₂ = ?
V₁/T₁ = V₂/T₂
V₂ = 10,5 L · 248 K ÷ 288 K
V₂ = 9,042 L.
<span>Answer:
Here is a more complex redox reaction involving the permanganate ion in acidic solution:
5Fe2+ + 8H+ + MnO4 --> 5Fe3+ +Mn2+ + 4H2O
Classify each reactant as the reducing agent, oxidizing agent, or neither.</span>
