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.

What is the difference between the reactions of concentrated hydrochloric acid and dilute hydrochloric acid with magnesium?
Concentrated hydrochloric acid is more reactive than dilute hydrochloric acid. When concentrated hydrochloric acid reacts with magnesium, it produces magnesium chloride and hydrogen gas more quickly and vigorously compared to when dilute hydrochloric acid reacts with magnesium. This is due to the higher concentration of hydrogen ions in concentrated hydrochloric acid, leading to a faster and more intense reaction.
What is the function of dilute hydrochloric acid on zinc metal and sodium carbonate?
zinc reacts with dilute HCl to form H2. This works to reduce (add Hydrogens to ) a compound
What would happen if hydrochloric acid reacts with magnesium oxide?
Magnesium Chloride and water would be formed. MgO + 2HCl ------> MgCl2 +H2O
Is reaction between magnesium and Hydrochloric acid is evolution reaction?
Yes, the reaction between magnesium and hydrochloric acid is an evolution reaction. When magnesium reacts with hydrochloric acid, it produces magnesium chloride and hydrogen gas. The release of hydrogen gas is indicative of an evolution reaction, as it signifies the transformation of reactants into products with the formation of a gas as a byproduct.
What does hydrochloric acid and magnesium produce?
When hydrochloric acid reacts with magnesium, it produces magnesium chloride and hydrogen gas as the products. This is a single replacement reaction where the more reactive magnesium displaces hydrogen in the acid to form the products.
When magnesium reacts with dilute hydrochloric acid what gas does it give off?
When magnesium reacts with dilute hydrochloric acid, it gives off hydrogen gas.
When magnesium carbonate is added to dilute hydrochloric acid what salt does it form?
Magnesium Chloride. MgCO3 +2HCl -----> MgCl2 + CO2 + H2O
What is the difference between the reactions of concentrated hydrochloric acid and dilute hydrochloric acid with magnesium?
Concentrated hydrochloric acid is more reactive than dilute hydrochloric acid. When concentrated hydrochloric acid reacts with magnesium, it produces magnesium chloride and hydrogen gas more quickly and vigorously compared to when dilute hydrochloric acid reacts with magnesium. This is due to the higher concentration of hydrogen ions in concentrated hydrochloric acid, leading to a faster and more intense reaction.
When zinc reacts with dilute hydrochloric acid does the temperature of the acid increase or decrease?
The temperature of the acid increases when zinc reacts with dilute hydrochloric acid because the reaction is exothermic, meaning it releases heat.
Which gas is produced when dilute hydrochloric acid poured on magnesite?
When dilute hydrochloric acid is poured on magnesite, carbon dioxide gas is produced. Magnesite is a mineral composed of magnesium carbonate, and when it reacts with hydrochloric acid, it forms magnesium chloride, water, and carbon dioxide gas.
What metal reacts steadily with dilute hydrochloride acid?
Copper reacts steadily with dilute hydrochloric acid to form copper chloride and hydrogen gas. The reaction is not as vigorous as with more reactive metals like magnesium or zinc.
What is the name of the new substance formed when Ammonia reacts with dilute hydrochloric acid?
Ammonium chloride is formed when ammonia reacts with dilute hydrochloric acid.
What reaction would happen with magnesium and dilute hydrochloric acid?
Mg + 2HCl --> MgCl2 + H2 A reaction producing a salt, magnesium chloride, and hydrogen gas.
What mineral that reacts to dilute hydrochloric acid?
Calcite is a mineral that reacts to dilute hydrochloric acid by fizzing or effervescing due to the release of carbon dioxide gas.
Which metals react with dilute hydrochloric acid?
Metals such as magnesium, zinc, iron, and aluminum can react with dilute hydrochloric acid to produce hydrogen gas and metal chloride salts. Copper, silver, and gold do not react with hydrochloric acid under normal conditions.
What is the enthalpy change when hydrochloric acid reacts with magnesium?
The enthalpy change when hydrochloric acid reacts with magnesium is exothermic, meaning it releases heat energy.
What is the enthalpy change when magnesium reacts with hydrochloric acid?
The enthalpy change when magnesium reacts with hydrochloric acid is exothermic, meaning it releases heat energy.
