En un experimento hacemos reaccionar 12 g de carbono con 32 g de oxígeno para formar dióxido de carbono. Razona si podemos saber
max2010maxim [7]

Answer:

La masa de óxido de carbono iv formado es 44 g.

Explanation:

En esta pregunta, se nos pide calcular la masa de óxido de carbono iv formado a partir de la reacción de masas dadas de carbono y oxígeno.

En primer lugar, necesitamos escribir una ecuación química equilibrada.

C + O2 → CO2

De la ecuación, 1 mol de carbono reaccionó con 1 mol de oxígeno para dar 1 mol de óxido de carbono iv.

Ahora, si marca las masas en la pregunta, verá que corresponde a la masa atómica y la masa molar de la molécula de carbono y oxígeno, respectivamente. ¿Qué indica esto?

Como tenemos una relación molar de 1: 1 en todo momento, lo que esto significa es que la masa de óxido de carbono iv producida también es la misma que la masa molar de óxido de carbono iv.

Por lo tanto, procedemos a calcular la masa molar de óxido de carbono iv Esto es igual a 12 + 2 (16) = 12 + 32 = 44 g Por lo tanto, la masa de óxido de carbono iv formado es 44 g

Lelechka [254]

gas to liquid

Explanation:

The change of state indicated by this analogy is from gas to liquid.

Cylinder to the left is filled with gases

Cylinder to the right is made up of liquid.

  • Gases occupy the volumes of containers they are introduced into.
  • They are random and possess a high kinetic energy.
  • Liquids have definite volume and flow with one another.
  • The gases in A are dispersed and in random motion.
  • This phase change is called condensation

The following solutions are prepared by dissolving the requisite amount of solute in water to obtain the desired concentrations.
daser333 [38]

Answer:

C₆H₁₂O₆ < NaCl ≈ CH₃OH < MgCl₂

Step-by-step explanation:

The formula for <em>osmotic pressure</em> (Π) is

Π = icRT

If T is constant,

Π = kic

<em>C₆H₁₂O₆: </em>

Π = k × 1 × 1 = k

<em>MgCl₂: </em>

Π = k × 3 × 1 = 3k

<em>CH₃OH: </em>

Π = k × 1 × 2 = 2k

<em>NaCl: </em>

Π = k  × 2 × 1 = 2k

The order of osmotic pressures is  

C₆H₁₂O₆ < NaCl ≈ CH₃OH < MgCl₂
