Answer:

multiple voltaic cells that have spontaneous half reactions

Explanation:

A battery is an electrochemical device that stores energy. This is connected to an electrical circuit, and chemical energy is transformed into electrical energy. All are similar in construction, each of these cells is composed of a positive and a negative electrode in addition to a separator. When the battery is discharged, an electrochemical change occurs between the different materials in the two electrodes. The electrons are transported between the positive and negative electrodes through an external circuit (light bulbs, starter motors, etc.)

Answer:

<h3>The answer is option C</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of liquid = 15 mL

density = 2.5 g/mL

We have

mass = 15 × 2.5

We have the final answer as

<h3>37.5 g</h3>

Hope this helps you

At a temperature of -25 °C, a sample of gas in a rigid container exerts a pressure of 55.8 kPa. At what temperature will the pre

never [62]

<h3>Given:</h3>

$P_{1} = \text{55.8 kPa}$

$T_{1} = -25^{\circ}\text{C + 273 = 248 K}$

$P_{2} = \text{145 kPa}$

<h3>Unknown:</h3>

$T_{2}$

<h3>Solution:</h3>

$\dfrac{P_{1}}{T_{1}} = \dfrac{P_{2}}{T_{2}}$

$T_{2} = T_{1} \times \dfrac{P_{2}}{P_{1}}$

$T_{2} = \text{248 K} \times \dfrac{\text{145 kPa}}{\text{55.8 kPa}}$

$\boxed{T_{2} = \text{644 K}}$
