The answer is C, Pb 2+(aq) + CO3(aq) PBCO3(s)
Answer:
water
Explanation:
because it's capable of dissolving more substances
Answer:
V = 42.6 L
Explanation:
Given data:
Number of moles of Cl₂ = 1.9 mol
Temperature and pressure = standard
Volume occupy = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
By putting values,
1 atm × V = 1.9 mol ×0.0821 atm.L /mol.K × 273.15 k
V = 42.6 atm.L / 1 atm
V = 42.6 L
Answer:
0.43 M
Explanation:
Use the dilution equation: M1V1 = M2V2
M1 = 13 M
V1 = 10 mL
M2 = ?
V2 = 300 mL
Solve for M2 --> M2 = M1V1/V2
M2 = (13 M)(10 mL) / (300 mL) = 0.43 M
