What three ways would let you know that a reaction of a metal had taken place?
Observation of a change in the appearance of the metal, such as discoloration or formation of a patina. Production of bubbles or gas, indicating a chemical reaction is occurring. Increase in temperature or release of heat during the reaction.
What three ways would let you know that a reaction had taken place?
Changes in color: If the color of the reactants or products changes during the reaction, it is a sign that a chemical reaction has occurred. Formation of a gas: Production of gas bubbles or fizzing indicates a chemical reaction, such as in the reaction between an acid and a carbonate. Changes in temperature: If the reaction absorbs or releases heat, causing a change in temperature in the surroundings, it signals a chemical reaction has taken place.
Why does increase in temperature increase the rate of a reaction?
Increasing the temperature increases the kinetic energy of the reactant molecules, leading to more frequent and energetic collisions. This results in a higher probability of successful collisions with enough energy to overcome the activation energy barrier, ultimately increasing the rate of the reaction.
What is catalysis give example?
Catalysis is the use of a catalyst in a reaction.Certain substances, called catalysts, can increase the rate of a reaction without being consumed by it.An example is the decomposition of H2O2: 2222(aq)22Catalysts can be described as being homogeneousor heterogeneous.Homogeneous: reaction takes place within a single phase, as in the example above with the H2O2.Heterogeneous: reaction involves two different phases, as in the example that follows. 2N2O ----> 2N2 + O2 - this reaction is usually slow, but if the reactants are bought into contact with a metal such as gold, the reaction speeds up considerably.A catalyst lowers the activation energy required for the reaction. Let me know if this helped or if there is a certain thing that you need me to cover about it.
When things burn they do what?
When things burn, they undergo a chemical reaction that releases heat and light. This process is known as combustion.

How do odyssesus and his men escape from the cave?
They first gave Polyphemus (the cyclopes) wine, so he became drunk and fell asleep. Then they took the stake and stabbed him in the eye, blinding him. Then they clung onto the bellies of the sheep and rams, so Polyphemus wouldn't feel them as he let them through. Then they took some of the herd and left

How did Odyssesus and his men escape from Plyphemus?
They first gave Polyphemus wine, so he became drunk and fell asleep. Then they took the stake and stabbed him in the eye, blinding him. Then they clung onto the bellies of the sheep and rams, so Polyphemus wouldn't feel them as he let them through. but as Poseidon was Polythemus's farther he cursed the rest of the voyage.
Does itching skin after sun burn mean something bad Since I got bad sunburn 5 weeks ago after it all healed one area on my shoulder has not stopped itching Horribly What does this mean?
You may be having a bad reaction to too much sun. I would go see your family physician or dermatologist. Don't let this go, for you may be having an allergic reaction to too much sun.

Fuel tends to explode or let the fire spread when it is lit.
How does Calypso feel about having to let Odysseus go?
sad
Why let say if the forward reaction is exothermic does this mean that the backward reaction gives out or take in heat and why?
If the forward reaction is exothermic then the back reaction would be endothermic. This happens because it upholds the law of conservation of energy, which says that energy cannot be created or destroyed.
What is the purpose of an invitation?
To let people know that you are having a party/ celebration when and where the party is, and how to let you know that they are coming to celebrate with you.
