Answer:

15 electrones: 1S²2S²2P⁶3S²3P³. Fósforo

27 electrones: 1S²2S²2P⁶3S²3P⁶4S²3d⁷ - Cobalto.

56 electrones: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s² - Bario

49 electrones: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p¹ - Indio

Explanation:

Para llenar los orbitales electrónicos de los distintos átomos debemos hacer uso de la regla de llenado electrónico de Aufbau. Por ejemplo, para el átomo con 15 electrones, la configuración electrónica es:

1S²2S²2P⁶3S²3P³. 2+2+6+2+3 = 15 electrones

Si elemento es neutro, tiene 15 protones. Es decir, es el fósforo, P.

27 electrones:

1S²2S²2P⁶3S²3P⁶4S²3d⁷ - Cobalto.

56 electrones:

1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s² - Bario

49 electrones:

1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p¹ - Indio

Imagine that you have a 6.50 L gas tank and a 4.50 L gas tank. You need to fill one tank with oxygen and the other with acetylen
Burka [1]

Answer:

We have to fill the acetylene tank with a pressure of 60.67 atm to ensure that you run out of each gas at the same time

Explanation:

Step 1: Data given

Volume of  tank 1 = 6.50 L = oxygen

Volume of tank 2 = 4.50 L = acetylene

Pressure in the oxygen tank = 105 atm

Step 2: The balanced equation

2 C2H2 + 5 O2 → 4 CO2 + 2 H2O

For 2 mol C2H2 we need 5 moles O2 to produce 4 moles CO2 and 2 moles H2O

 Step 3: Calculate the pressure of the acetylene tank

For 2 mol C2H2 we need 5 moles O2 to produce 4 moles CO2 and 2 moles H2O

This means for each 5 moles O2 we have 2 moles acetylene

Pressure (105 atm) * (2/5) * (6.50 / 4.50) = 60.67 atm

We have to fill the acetylene tank with a pressure of 60.67 atm to ensure that you run out of each gas at the same time

A student is monitoring the pressure of a gas in a rigid container. The amount of gas particles and the volume of the container
GenaCL600 [577]

a.The gas pressure will decrease.

Explanation:

If in a rigid container, the amount of gas particles and volume of the container is held constant, the pressure will decrease if the temperature is reduced.

  • Gases are highly random particles and they require a high amount of kinetic energy to be in their state of matter.
  • In a condition where volume of container is fixed, the amount of gas particles is fixed and the temperature reduced, the kinetic energy of the gas particles will directly reduce.
  • The kinetic energy of gases is directly related to temperature.
