Explanation:Mg(s)+Zn(NO3)2(aq) → Mg(NO3)2(aq)+Zn(s)
Answer: Option (D) 30N
Detailed Solution:
According to Newton's second law:
F = ma --- (A)
Given:
mass = 5kg
acceleration = 6 m/s^2
F = ?
Plug all the value in equation (A)
F = (5)(6)
Ans: F = 30N
<span> Because it is diprotic acid, we can write like R(COOH)2 ( it can be written as H2A also)
</span>R(COOH)2+2NaOH ----> R(COONa)2+2H2O
<span>25.0 ml of a 0.100 m NaOH solution
25.0 ml=0.0250 L solution Of NaOH
</span> 0.100 m NaOH=0.100 mol/L
0.0250 L *0.100 mol/L=0.00250 mol NaOH
0.00250 mol NaOH*1mol R(COOH)2/2 mol NaOH=0.00125 mol acid
0.00125 mol R(COOH)2*118g R(COOH)2/1mol R(COOH)2 = 0.148 g acid
Answer is 0.148 g <span>Succinic acid</span>
With time, it dissolves in water.
