When magnesium ribbon reacts with dilute hydrochloric acid what is the temperature?
When magnesium ribbon reacts with dilute hydrochloric acid, it produces magnesium chloride and hydrogen gas. This exothermic reaction typically results in a noticeable increase in temperature, although the exact temperature can vary based on the concentration of the acid and the amount of magnesium used. Generally, the temperature can rise significantly above room temperature, often reaching around 40-50°C, depending on specific conditions.
A neutralization reaction was carried out in a calorimeter The temperature of the solution rose from 20.0 C to 25.6 C Is this reaction endothermic or exothermic?
This reaction is exothermic because the temperature of the solution rose. In an exothermic reaction, heat is released to the surroundings, causing an increase in temperature.
Is temperature getting warmer a exothermic?
No, temperature getting warmer is not an exothermic process. An exothermic reaction refers to a process that releases heat to its surroundings, resulting in an increase in temperature of the surroundings. Conversely, a rise in temperature in a system can indicate an endothermic process, where heat is absorbed from the surroundings, or simply an increase in thermal energy without a chemical reaction occurring.
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
How are exothermic and endothermic reactions different?
Exothermic reactions release heat to the surroundings, causing the surroundings to increase in temperature. Endothermic reactions absorb heat from the surroundings, causing the surroundings to decrease in temperature.
Why does magnesium ribbon increase the temperature of hydrochloric acid?
When magnesium ribbon is added to hydrochloric acid, a chemical reaction occurs that releases energy in the form of heat. This reaction produces magnesium chloride and hydrogen gas, which results in an increase in temperature of the solution.
How does the temperature change when magnesium is added to an acid?
When magnesium is added to an acid, a chemical reaction occurs, producing magnesium ions and hydrogen gas. This reaction is exothermic, meaning it releases heat, which causes the temperature of the solution to increase. The extent of the temperature change depends on factors such as the concentration of the acid and the amount of magnesium added. Overall, the addition of magnesium to an acid typically results in a noticeable rise in temperature.
Why was the highest rise in temperature obtained with magnesium and copper sulphate?
because magnezium is more reactive

What do exothermic reactions achieve in terms of energy release and temperature change?
Exothermic reactions release energy in the form of heat, causing an increase in temperature.

When hydrochloric acid neutralizes sodium hydroxide the temperature increases is this exothermic or endothermic?
When the temperature increases as a result of reaction, as specified here, the reaction is exothermic.
How is exothermic reaction identified?
An exothermic reaction is identified by a release of heat energy. This can be observed by a temperature increase in the surroundings, production of light or sound, or feeling warmth. Additionally, exothermic reactions often result in a negative change in enthalpy (ΔH).
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
Which indicates an exothermic reaction?
A+B —> C+D+ HEAT (Apex)
Is Calcium chloride in water is endothermic or exothermic?
The dissolution of calcium chloride in water is exothermic, meaning it releases heat. This reaction results in an increase in temperature of the solution.
