When a person goes with their first reaction?
A term with a positive spin is a gut reaction. A term with a negative spin is a knee-jerk reaction.
What is a pethergy test?
A pathergy test is a skin-prick test to see if a red bump will form at the injection site. If there is a reaction, the test is positive. This test may be given to patients suspected of BD, but it is not an indicator for the disease.
How can you use a potato to light a light bulb?
Simple Potato Battery Select two different metal strips and one potato. Use a copper and a zinc coated metal strip. We need galvanized metal so the zinc can react. Carefully place the metal strips into the potato. Congratulations! You have just made a battery! Simple, yes? Now you will learn about your battery. Now, you may be wonder, what is causing a chemical reaction? Here is the explanation: 1. the potato has a mild phosphoric acid content H3PO4 2. reduction at Cu (copper) electrode: 2H+ + 2e- -> H2 gas 3. oxidation at Zn (zinc) electrode: Zn -> Zn++ + 2e- The H3PO4 acid puts the hydrogen ions in solution.
What is your reaction in the movie Make A difference?
my reaction is jayron and eldrich
What is the duration of The Chain Reaction?
The duration of The Chain Reaction is 1.53 hours.
What is the function of the positive electrode and negative electrode in a battery?
The positive electrode in a battery is where the electrons are released during the chemical reaction, while the negative electrode is where the electrons are received. This flow of electrons creates an electric current that powers the device connected to the battery.
How does a wet cell battery produce electrons to flow as electricity?
In a wet cell battery, a chemical reaction occurs between the electrolyte and the electrodes, creating an excess of electrons at the negative electrode (anode) and a deficit at the positive electrode (cathode). This imbalance causes the electrons to flow from the negative electrode to the positive electrode through the external circuit, generating electricity.
What happens when sodium ions come in contact with the negative electrode in a cell used for electrolysis?
When sodium ions come in contact with the negative electrode in a cell used for electrolysis, they accept electrons and get reduced to form sodium metal. This process occurs as part of the overall electrolysis reaction, where positive ions are reduced at the negative electrode while negative ions are oxidized at the positive electrode.
Why electric potential of hydrogen is written as plus -0.00?
The electric potential of hydrogen, often represented as +0.00 volts, refers to the standard electrode potential of the hydrogen electrode, which is defined as the reference point for measuring other electrode potentials. This value is assigned to the hydrogen half-reaction under standard conditions (1 M concentration, 1 atm pressure, and 25°C). The positive sign indicates that hydrogen is a reducing agent, meaning it can donate electrons in electrochemical reactions. The convention helps standardize measurements in electrochemistry.
When the electrode held by the esthetician is in the positive mode the reaction on the skin will be?
When the electrode held by the esthetician is in the positive mode, the reaction on the skin typically involves a mild desquamation effect and a decrease in oiliness due to the positive charge attracting negatively charged particles. This can promote a sense of tightening and may enhance the absorption of skincare products. Additionally, it can stimulate circulation and contribute to a brighter complexion by promoting blood flow.
How a carbon-zinc dry cell supplies electric current for a CD player?
A carbon-zinc dry cell supplies electric current by converting chemical energy into electrical energy through a chemical reaction between the carbon rod (negative electrode) and the zinc can (positive electrode). When connected in a circuit, electrons flow from the anode (zinc) to the cathode (carbon), generating a flow of electric current. This current can power a CD player by providing the necessary energy to operate its electronic components.
What is the relationship between the working electrode and counter electrode in electrochemical reactions?
In electrochemical reactions, the working electrode and counter electrode are two essential components that work together. The working electrode is where the chemical reaction takes place, while the counter electrode completes the circuit and balances the charge. They are connected through an electrolyte solution, allowing the flow of ions to facilitate the reaction. The working electrode drives the reaction, while the counter electrode ensures that the overall charge remains balanced.
What is the half reaction of a saturated calomel electrode?
The half reaction of a saturated calomel electrode is Hg2Cl2(s) 2e- - 2Hg(l) 2Cl-
What is a nagtive protein and what is a positive protein?
During an incidence of inflammation, the body will respond with an acute-phase reaction. The acute -phase proteins whose plasma concentrates increase , positive proteins or decrease, negative proteins in response.
Is the electrode the metal or graphite rod in an electric cell?
Tt depends on the metal which is the cathode and which is the anode. However, in most cases, graphite is the cathode and the metal is the anode. the strictly correct answer is that BOTH the metal and the graphite rod are electrodes. You must have two electrodes minimum to create a cell.
Why chlorine gas forms at the positive electrode?
At the positive electrode electrons are removed from the solution. If chloride ions (Cl-) are present the will each lose and electron to form chlorine atoms, which then bond together to from Cl2 molecules, which is chlorine gas. Chlorine is extremely toxic, which is why you shouldn't use table salt (sodium chloride) as an electrolyte.
What is an oxidising electrode?
according to me anode should be oxidizing electrode as oxidation reaction takes place on anode
