 The  specific  heat  of silver   is calculated as  below

Q(heat)  =  M(mass) xC(specific heat capacity)  

Q= 42.8 j/c

M=181 g
C=?
by  making  C  the subject of the formula

C= Q/M

C= 42.8 j/c/181 g  =0.236j/g/c

En una determinación cuantitativa se utilizan 17.1 mL de Na2S2O3 0.1N para que reaccione todo el yodo que se encuentra en una mu
lozanna [386]

Answer:

La cantidad de yodo en la muestra es 0.217 g

Explanation:

Los parámetros dados son;

Normalidad de la solución de Na₂S₂O₃ = 0.1 N

Volumen de la solución de Na₂S₂O₃ = 17.1 mL

Masa de muestra = 0.376 g

La ecuación de reacción química se da de la siguiente manera;

I₂ + 2Na₂S₂O₃ → 2 · NaI + Na₂S₄O₆

Por lo tanto, el número de moles de sodio por 1 mol de Na₂S₂O₃ en la reacción = 1 mol

Por lo tanto, la normalidad por mol = 1 M × 1 átomo de Na = 1 N

Por lo tanto, 0.1 N = 0.1 M

El número de moles de Na₂S₂O₃ en 17,1 ml de solución 0,1 M de Na₂S₂O₃ se da de la siguiente manera;

Número de moles de Na₂S₂O₃ = 17.1 / 1000 × 0.1 = 0.00171 moles

Lo que da;

Un mol de yodo, I₂, reacciona con dos moles de Na₂S₂O₃

Por lo tanto;

0,000855 moles de yodo, I₂, reaccionan con 0,00171 moles de Na₂S₂O₃

La masa molar de yodo = 253.8089 g / mol

La masa de yodo en la muestra = 253.8089 × 0.000855 = 0.217 g.

Which of the following is not the same as 0.032 liters?
sineoko [7]
This question needs the answer choices.

I found these choices for you:
<span>0.00032hL
320cL
32mL

Then  you need to make the conversion of 0.032 liters to hectoliters, centiliters and milimilters to check which is not equivalent.

1) 0.032 liters to hectoliters:

    0.032 liter *  1 hectoliter / 100 liter = 0.00032 hecoliter

2) 0.032 liter to centiliters:

    0.032 liter * 100 centiliters / 1 liter = 3.2 centiliter

3) 0.032 liter to mililiter:

    0.032 liter * 1000 mililiter / liter = 32 mililiter

Then, the answer is 320 cL: 320 cL is not the same as 0.032 liters
