Answer:

La pregunta no es clara, asi que voy a dar una breve descripicion de la termodinamica y alguno de los fenomenos que estudia

La termodinámica es la rama de la física que estudia los sistemas en equilibrio termodinámico (es decir, aquellos sistemas que no pueden sufrir un cambio espontáneo). Particularmente, la termodinámica estudia los procesos de flujo de calor (lo podemos ver en su nombre, dinámica del calor) y se relacionan estos cambios de energía con el trabajo que es posible obtener.

Entonces, por ejemplo, la termodinámica estudia como el hielo puede cambiar de fase (a medida que aumenta su temperatura) y convertirse en agua líquida.

La termodinámica también estudia como funcionan máquinas de calor, como motores de pistones, y el trabajo que estos son capaces de realizar.

Como ejemplo final, con la termodinámica podemos estudiar cosas tan complejas como equilibrio entre distintas fases (por ejemplo, el porqué podemos tener agua y hielo en equilibrio termodinámico, un ejemplo de esto son las superficies de ríos que se congelan mientras la parte inferior sigue siendo líquida)

Esos son, entre muchísimos otros, 3 posibles efectos que suceden a nuestro alrededor, y son estudiados por la termodinámica.

What is the SI base unit for length?
sp2606 [1]

The SI base unit for length is meter.

In order to make smaller measurements, you can use the centi-, milli-, micro-, etc. prefixes.

When you want to reference larger measurements, you can use the kilo-, mega-, giga- and prefixes such as those.

What is the molarity of a solution in which 7.1 g of sodium sulfate is dissolved in enough water to make 100. mL of solution?
Sidana [21]

Answer:

0.50 M

Explanation:

Given data

  • Mass of sodium sulfate (solute): 7.1 g
  • Volume of solution: 100 mL

Step 1: Calculate the moles of the solute

The molar mass of sodium sulfate is 142.04 g/mol. The moles corresponding to 7.1 grams of sodium sulfate are:

7.1g \times \frac{1mol}{142.02g} = 0.050mol

Step 2: Convert the volume of solution to liters

We will use the relation 1 L = 1000 mL.

100mL \times \frac{1L}{1000mL} =0.100L

Step 3: Calculate the molarity of the solution

M = \frac{moles\ of\ solute }{liters\ of\ solution} = \frac{0.050mol}{0.100L} =0.50 M

Part V Write the (a) half reaction of oxidation, (b) half reaction of reduction, & (c) the balanced redox reaction for all o
Eduardwww [97]

Answer:

Explanation:

a. Oxidation : 2O + 4e^- ------> 2O^2-

b. Reduction: 2Sr - 4e- -------> Sr^2+

c. Balanced redox reaction

2Sr + O2 ------------> 2Sr O

Oxidation and reduction can be defined by various means, addition of oxygen, removal of hydrogen, removal of electrons. For this reaction, this definition is used, oxidation is the loss of electrons while reduction is the gaining of electrons.

In (a) oxidation half reaction, the valency of oxygen is zero and then moves into lossing two electrons resulting into -2 valency.

In (b) reduction half reaction, the valency of Sr is zero and gains electrons resulting into valency of 2.

In the overall redox reaction, Sr and O2 with valency of 0 each reacts together and form SrO with valency of 2 and -2 respectively, which gives 0 and then balances the equation.

On a summer day, you take a road trip through Death Valley, California, in an antique car. You start out at a temperature of 21°
MrRissso [65]
<span>There is only one formula to use and we should assume ideal gas. This equation is: PV=nRT. For the following questions manipulate this equation to get the answer.
 1. n = PV/RT = (249*1000 Pa)(15.6 L)(1 m^3/1000 L)/(8.314 Pa-m^3/mol-K))(21+273) = 1.59 mol
 2. P = nRT/V = (1.59)(8.314)(51+273)/(15.6/1000)(1000) = 274.55 kPa
 3. Since the answer in #2 is more than 269 kPa, then the tires will likely burst. 4. Reduce pressure way below the limit 269 kPa.</span>
