Answer:
Your cation is Pb2+
Explanation:
This is the explanation by chemical reactions
HCl (l) ----> H+(aq) + Cl-(aq)
Pb2+(aq) + 2Cl-(aq) ---> PbCl2 (s) ↓
H2SO4 (l) ----> 2H+ (aq) + SO4-2(aq)
Pb2+(aq) + SO4-2(aq) ---> PbSO4 (s) ↓
NaOH (l) ---> Na+(aq) + OH-(aq)
Pb2+(aq) + 2OH-(aq) ---> Pb(OH)2 (s) ↓
If the reaction takes place in a strong alkaline medium, lead hydroxide dissolves in excess of base
Answer:
<u>The new pressure is 1.0533 atm</u>
<u></u>
Explanation:
According to<u> Boyle's Law :</u> The Pressure of fixed amount of gas is inversely proportional to Volume at constant temperature.
PV = Constant
P1V1 = P2V2
.....(1)
P1 = 3.16 atm
Accprding to question ,
V1 = V
V2 = 3 V
Insert the value of V1 , V2 and P1 in the equation(1)


V and V cancel each other



Answer:
12
Explanation:
If GT bisects BN at point G, then point G would be in the middle of BN. So, since Bg and NG have to be equal and add up to 24, then the answer is 12.
Your correct answer is C. 97%
