indicate if the following statements are true or false for a standard galvanic cell. oxidation occurs at the anode reduction occ

Masja [62]

An anode is an electrode, it can be a metal or another conductor. in an electrochemical cell that is polarized if an electric current flows into it. Electric current flows opposite to the direction of movement of electrons. In electrochemical processes, both galvanic cells (batteries) and electrolysis cells, anodes undergo oxidation.

In contrast to an Anode, a Cathode is an electrode pole in an electrochemical cell that is polarized if this pole is positively charged (so that an electric current will flow out of it, or the movement of electrons will enter this pole).

In galvanic cells or power plants (batteries), the anode is the negative pole. The electrode will release electrons towards the circuit and hence an electric current flows into this electrode and makes it an anode and negative.

Wood has a density of 0.531 g/cm3. What is the volume of 44 grams of wood?

Sunny_sXe [5.5K]

Answer:

<h3>The answer is 82.86 cm³</h3>

Explanation:

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

$volume = \frac{mass}{density} \\$

From the question

mass of wood = 44 g

density = 0.531 g/cm³

It's volume is

$volume = \frac{44}{0.531} \\ = 82.86252354...$

We have the final answer as

Hope this helps you

Answer:

2.09 atm

Explanation:

We can solve this problem by using the equation of state for an ideal gas, which relates the pressure, the volume and the temperature of an ideal gas:

$pV=nRT$
