Does magnesium give off heat when it burns?
Yes, when magnesium burns, it reacts with oxygen to form magnesium oxide and releases heat in the process. The heat generated during this exothermic reaction is what causes the bright white light observed when magnesium burns.
What term is used for the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
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.
What color does phenolpthalein turn in the presenc of an acid?
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.
When a chemical reaction takes in more energy than it gives off it becomes what?
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
Which element gives dazzling light when it burns in air?
Magnesium is the element that gives dazzling light when it burns in air. This is due to the intense white light produced as a result of the combustion reaction with oxygen.
When a candle burns it gives off carbon dioxide and?
WATER! H2O it is a combustion reaction and every combustion reaction produces carbon dioxide and water
What happens when aluminium metal is added to dilute hcl?
When aluminum metal is added to dilute hydrochloric acid (HCl), hydrogen gas is produced as a result of the reaction. The aluminum metal reacts with the hydrochloric acid to form aluminum chloride and hydrogen gas. This reaction is a single displacement reaction where aluminum displaces hydrogen from the hydrochloric acid.
Does magnesium give off heat when it burns?
Yes, when magnesium burns, it reacts with oxygen to form magnesium oxide and releases heat in the process. The heat generated during this exothermic reaction is what causes the bright white light observed when magnesium burns.
What is the balanced equation for the reaction of action of dilute acid on a metal?
The balanced equation for the reaction of a metal with a dilute acid is typically represented as: Metal + Acid → Salt + Hydrogen gas. For example, the reaction of zinc (Zn) with hydrochloric acid (HCl) forms zinc chloride (ZnCl2) and hydrogen gas (H2).
What burns and gives off water and carbon dioxide?
A hydrocarbon like methane, propane, or gasoline burns in the presence of oxygen to give off water vapor and carbon dioxide. This is a common chemical reaction that occurs during combustion.
What will happen if lead is allowed to react with dilute acid?
Reactions of Lead (Pb) with cold, dilute acids are very slow. Some examples are as follows:- 1) Reaction with dil. HCl and gives PbCl2 and H2 gas. Pb + 2HCl ---> PbCl2 + H2 Solid Aqs. Aqs. Gas 2) Reaction with dil. H2SO4 and gives PbSO4 and H2 gas. Pb + H2SO4 ----> PbSO4 + H2 Solid Aqs. Aqs. Gas 3) Reaction with dil. HNO3 and gives Pb(NO3)2 and H2 gas. Pb + 2HNO3 ------> Pb(NO3)2 + H2 Solid Aqs. Aqs. Gas Regards- Ashutosh talktomehiya@gmail.com
A small amount of solute versus the amount of solvent?
This gives you a dilute solution.
What is xenon's characteristic color?
Xenon is generally colourless, however when electricity is passed, it gives out a lovely pale violet colour.
What term is used for the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
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.
Is Zinc and dilute Sulphuric acid gives Hydrogen gas for filling balloon?
No, because it is ignite.
