Heat is always released in exothermic reactions.
Sodium Hydroxide and Sulphuric Acid!
magnesium
Usually by reacting with an alkali.
Yes because make the chalk into a powder increases its surface area so it is more likely to react, so rate of reaction is increased
it is a neutralization reaction.
Neutralization occurs when an acid reacts with an alkali to make a neutral substance pH 7.
acid + alkali = salt + water.Acids are proton donors, they donate a H+ (aq) ion (a hydrogen ion). Acids have pH values of less than 7.Alkalis are proton acceptors, they donate a -OH (aq) ion (a hydroxide ion). Alkalis have a pH value of above 7.They react together to make a neutralisation reaction.The pH scale is a numerical scale from approximately 0 to 14 which measures how strong an acid or an alkali is.If you use hydrochloric acid you will form a chloride salt.If you use sulphuric acid you will form a sulphate salt.If you use nitric acid you will form a nitrate salt.For example:hydrochloric acid + sodium hydroxide = sodium chloride + waterIf you react an acid and an alkali you always get a salt + water.An alkali is NOT THE OPPOSITE OF AN ACID!!! The opposite of an acid is called a BASE. An alkali is a base that is soluble in water (e.g. sodium hydroxide, lithium hydroxide, ammonia)Neutralization.
Salts are the products of a reaction between an acid and a base; a common example: NaOH + HCl = NaCl + H2O
When an acid and an alkali is combined, salt and water is formed, because the acid and the alkali neutralises each other to leave salt and water only.
When KOH reacts with HCl, these products are formed. This is a neutralization reaction. KOH is a base while HCl is an acid.
Heat is always released in exothermic reactions.
Sodium Hydroxide and Sulphuric Acid!
1. Generally salts are the products of a neutralization reaction - between a base and an acid. 2. Sodium chloride can be obtained also from the reaction between sodium and chlorine.
because your body naturally produces acids which can burn your thought so the alkali neutralises the acid to make it not a strong acid
hydrochloric acid and sodium hydroxide
Water and sulfur
