Does nickel react with silver nitrate?

Does nickel react with silver nitrate?

Nickel replaces silver from silver nitrate in solution according to the following equation: 2AgNO3+Ni→2Ag+Ni(NO3)2.

Does a reaction occur when aqueous solutions of nickel II chloride and silver I nitrate are combined?

Answer : YES, the reaction will occur.

Why do single replacement reactions occur?

A replacement reaction occurs when elements switch places in compounds. This type of reaction involves ions. Generally, more reactive elements replace less reactive elements. A single replacement reaction occurs when one element replaces another element in one compound.

What Law does a balanced equation satisfy?

Conservation of matter or mass is the law that satisfies when we balance an equation , we determine the ratio of reactants to products which allows for the total number of atoms of reactants to match the number of atoms of the products.

Why is Bond making exothermic?

BREAKING AND FORMING BONDS Bond breaking is an endothermic process, because it requires energy. Bond forming is an exothermic process, because it releases energy.

Why does K decrease when temperature increases?

le Châtelier’s principle allows us to predict that if the temperature increases, then the reaction will shift to the left – in other words, the concentration of R will increase, while P will decrease. This means that K will decrease.

What is the enthalpy change for an exothermic reaction?

Exothermic reaction: In an exothermic reaction, the total energy of the products is less than the total energy of the reactants. Therefore, the change in enthalpy is negative, and heat is released to the surroundings.

Is enthalpy defined only at constant pressure?

Is change in enthalpy defined only at constant pressure? No. The definition of ΔH is ΔH=ΔU+Δ(PV) Simple as that. Only if the applied pressure is held constant during the change.

Is breaking bonds exothermic?

Breaking bonds between atoms requires energy. Creating new bonds releases it. For this reaction, the energy released is larger than the energy absorbed. This means combustion has an overall negative enthalpy and is an exothermic reaction.

Is evaporating exothermic?

Evaporation is endothermic. For condensation the molecules are giving up their heat energy. When molecules give up heat energy, it is called exothermic.

Is Melting ice exothermic?

Basically, melting ice is an endothermic reaction because the ice absorbs (heat) energy, which causes a change to occur.

Is water freezing exothermic?

When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction.

Is evaporating alcohol endothermic or exothermic?

What kind of process (endothermic or exothermic) is evaporation? Endothermic because it draws heat from the surrounding, rather than giving it off. Explain how evaporation is part of phase change. Evaporation is the phase of change because it is the changing of liquid to gas.

Is a hot cup of coffee cooling on a countertop endothermic?

Is a hot cup of coffee (system) cools on a countertop endothermic or exothermic? The system lost heat and did work on the surroundings.

Is baking a potato exothermic or endothermic?

Endo. Potato (system) is absorbing heat from the oven (surrounding) causing it to cook.

Is steam condensing endothermic or exothermic?

The same amount of heat will be released when the steam condenses to liquid water, at 100 deg. C. So, it is an exothermic process, and releases the caloric amount of Latent Heat of Vaporization for the mass of steam that condenses.

Is digestion of food endothermic or exothermic?

Digestion is an Exothermic reaction as it breaks down the complex particles into simpler particles which is then further broken down , from here the process of absorption takes places which is essentially an endothermic reaction. Also,Exothermic reaction takes place when you run or perform a physical task.

How is digestion an exothermic reaction?

Digestion is an exothermic reaction. During the process of digestion complex substances such as starch carbohydrates and proteins are broken down into simpler form such as simple sugar and amino acids respectively. Since energy is produced in the process of digestion ,it is an exothermic reaction.

Is metabolizing food exothermic?

A typical exothermic reaction would be the metabolism of glucose. The glucose molecule is highly energetic and our body has learned to break it down through a series of reactions that turn glucose into carbon dioxide and water.
