Describe the nature of electrochemical process.

Answers

Answer:

electrochemical process is a chemical reaction caused by the applied electrical current.

Explanation:

Electrochemical processes involve the transfer of electrons between chemical species, resulting in the conversion of chemical energy into electrical energy or vice versa.

Through redox reactions, chemical energy can be transformed into electrical energy or vice versa in electrochemical processes. They happen where an electrode and an electrolyte solution meet. In these procedures, electrons are moved from the electrode to the electrolyte, causing an electric current to flow.

While reduction takes place at the cathode, where electrons are obtained, oxidation happens at the anode, where electrons are expelled. Numerous applications, such as batteries, fuel cells, corrosion, electroplating, and electrolysis, depend on electrochemical processes.

Jim needs to conduct his experiment at STP .Which condition must he use?

Answers

Answer:

273 K, 101.3 kPa

Explanation: I just did the quiz

To acquires STP condition, Jim must apply a temperature 298 K and 1 atm pressure. At STP condition one mole of all gases occupies a volume of 22.4 liters.

What is STP condition ?

The standard temperature and pressure is called STP condition. A temperature  of 298 K and pressure of 1 atm is called standard temperature and pressure.

At STP condition, the volume of one mole of any substance is 22.4 liters. One mole corresponds to 6.02 × 10²³ molecules. By satisfying the STP condition, we can determine the volume, and other mole parameters of a compound.

Experiments can be conducted at STP condition by applying a temperature of 298 K which is equal to 25°C and a pressure of  1 atm. He can use a thermometer and barometer to measure and set the values of temperature and pressure.

How many moles in 67.8 g of F2 ( Fluorine compound)?

Answers

Answer:

1.78 moles

Explanation:

to find moles, use the formula moles=mass/rfm

the rfm is the mass number (the bigger number) on the element's square thingy on the periodic table

the mass number of fluorine is 19

19*2 (because it's diatomic you multiply it by 2) =38

so 67.8/38=1.78421052632

round it to 2 sf= 1.78 moles

How does nickel make stainless steel not magnetic?.

Answers

The nickel, itself ferromagnetic, reduces the magnetism in stainless steel but not to zero. Austenitic stainless steel is defined as the steel crystal structure that is face centered cubic which is the same structure hot iron has as one of the allotropes of iron. Nickel above a certain percentage (18) stabilizes austenite structure just as if you took carbon steel and heated it above 730–770 C. Above this temperature the structure is FCC and above the Currie temperature where magnetism is killed due to the isotopic symmetry of the structure. However, you can still get a small magnetic attraction from austenitic stainless steel if it is cold worked, heat treated a certain way or welded. So it is not a guarantee that austenitic stainless is totally non magnetic.

If further increases in substrate concentration do not result in further increases in reaction rate, then an enzyme is likely

Answers

Given what we know, we can confirm that if further increases in substrate concentration do not result in further increases in reaction rate, then an enzyme is likely saturated.

What does it mean for an enzyme to be saturated?

Enzymes work by binding to the substrate in specific zones of the enzyme. The zones are known as the active sites on enzymes. Since enzymes have a limited amount of these zones, once they are all bonded to a substrate, we can say that it is saturated.

Therefore, the saturation of enzymes allows us to explain how further increases in substrate concentration do not result in further increases in reaction rate.
