Answer:

b) 2H+(aq) + 2C1-(aq) + Zn(s) → H2(g) + Zn2+(aq) + 2Cl-(aq)

Explanation:

The equation is given as;

2HCl(aq) + Zn(s) + H2(g) + ZnCl2(aq)

In writing an ionic equation, only the aqueous compounds dissociates into ions. This means HCl and ZnCl2 would dissociate to form ions.

This is given as;

2H+ + 2Cl- + Zn(s) --> H2(g) + Zn2+ + 2Cl-

The correct option is;

b) 2H+(aq) + 2C1-(aq) + Zn(s) → H2(g) + Zn2+(aq) + 2Cl-(aq)

Two gas-containers, A and B, are connected with a valve. The first container, A, has a volume of 135 mL, and the second containe

stiv31 [10]

Answer:

85.5 mmHg is the pressure of the gas sample when the valve is opened.

Explanation:

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas in container A = 165 mmHg

$P_2$ = final pressure of gas = ?

$V_1$ = initial volume of gas in container A= $135 mL$

$V_2$ = final volume of gas = 135 mL + 117 mL = 252 mL

$T_1$ = initial temperature of gas in container A = $22.5^oC=273+22.5=295.5 K$

$T_2$ = final temperature of gas = $12.7^oC=273+12.7=285.7K$

Now put all the given values in the above equation, we get:

$P_2=\frac{P_1V_1\times T_2}{T_1\times V_2}$

$=\frac{165 mmHg\times 135 mL\times 285.7 K}{295.5 K\times 252 mL}$

$P_2=85.5 mmHg$

85.5 mmHg is the pressure of the gas sample when the valve is opened.

3AgNO₃ + Na₃PO₄ → Ag₃PO₄ + 3NaNO₃

Explanation:

AgNO₃+Na₃(PO₄) → Ag₃(PO₄) + NaNO₃

To balance this chemical equation, we can adopt a simple mathematical approach through which we can establish simple and solvable algebraic equations.

aAgNO₃ + bNa₃PO₄ → cAg₃PO₄ + dNaNO₃

a, b, c and d are the coefficients needed to balance the equation.

Conserving Ag: a = 3c

N: a = d

O: 2a + 4b = 4c + 2d

Na: 3b = d

P: b = c

let a = 1; d = 1

b = $\frac{1}{3}$

c = $\frac{1}{3}$

Multiplying through by 3:

a = 3, b = 1, c = 1 and d = 3

3AgNO₃ + Na₃PO₄ → Ag₃PO₄ + 3NaNO₃
