Answer:

Solids have the lowest kinetic energy so vibrate very little. Liquids have more kinetic energy so particles slide past each other. Gases have the most kinetic energy so fly around in the air

Choose the correct net ionic equation for the reaction (if a reaction occurs) between CaCl2 and AgNO3: Group of answer choices
Levart [38]

Answer:

2Ag⁺(aq) + 2Cl⁻(aq) -> 2AgCl(s)

Explanation:

Silver nitrate and calcium chloride will react in a double displacement reaction (which has to produce a precipitate, a gas, or water to have a reaction).

This reaction will produce a silver chloride precipitate and a solution of calcium nitrate.

The reaction will be 2AgNO3(aq) + CaCl2(aq) -> 2AgCl(s) + Ca(NO3)2(aq)

To write a net ionic equation:

1. Write the balanced molecular equation.

   2AgNO3 + CaCl2 -> 2AgCl(ppt) + Ca(NO3)2

2. Write the balanced complete ionic equation.

To write the complete ionic equation:

- Start with a balanced molecular equation.

2AgNO3(aq) + CaCl2(aq) -> 2AgCl(s) + Ca(NO3)2(aq)

- Break all soluble strong electrolytes (compounds with (aq) beside them) into their ions

       indicate the correct formula and charge of each ion

       indicate the correct number of each ion

       write (aq) after each ion

- Bring down all compounds with (s), (l), or (g) unchanged.

2Ag⁺(aq) + 2NO³⁻(aq) + Ca²⁺(aq) + 2Cl⁻(aq) -> 2AgCl(s) + Ca²⁺(aq) + 2NO³⁻(aq)

3. Cross out the spectator ions that are present. Spectator ions are ions that are present in the reaction mixture but do not participate in it. You can recognize spectator ions by looking for ions that are present on both sides of the equation.

4. Write the "leftovers" as the net ionic equation.

2Ag⁺(aq) + 2Cl⁻(aq) -> 2AgCl(s)

En una planta de energía, se produce CO2 gracias a la reacción de combustión del material orgánico con oxígeno para producir CO2
Mamont248 [21]

Answer:

a. Gases ideales: relación entre todas las variables que influyen sobre los gases

Explanation:

La ecuación del gas ideal da la relación entre las variables; presión, volumen, temperatura y número de moles.

Según la ecuación del gas ideal; PV = nRT

P = presión del gas

V = volumen del gas

n = Número de moles del gas

R = constante de gas

T = temperatura del gas

El número de moles de SO2 se obtiene de;

n = PV / RT

n = 0,5 * 25 / 0,082 * 373

n = 12,5 / 30,586

n = 0,41 moles
