What is a change that has the same substances as reactants and products?
It is a change in state. For instance, water may undergo boiling to form water vapour. The reactants and products are chemically the same, which is H2O. Another example would be the sublimation of ammonium chloride, where it changes directly from a solid to a gas.The change from reactants to products is called as a chemical reaction. According to the key reaction involved there are several types of reactions. For example, an acid and a base undergo a neutralization reaction to produce a salt and water as products.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
A chemical reaction has not occurred if the products have?
The same chemical properties as the reactants.
What is the purpose for the arrow between the reactants and products in a chemical reaction?
it acts as an equal sign --> is the same thing as = in a chemical reaction. Or perhaps better is interpreted as 'becomes' and indicates the direction of the reaction.
According to the law of conservation of mass how many atoms of calcium can react to produce more calcium?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction, only rearranged. This means that the number of calcium atoms present before the reaction must be the same as the number of calcium atoms present after the reaction. Therefore, if a certain number of calcium atoms react to produce more calcium, the total number of calcium atoms will remain the same.
How do you write e the balanced chemical equation for reaction of aqueous hydrobromic acid reacts with aqueous sodium hydroxide to form liquid water and aqueous sodium bromide?
The balanced chemical equation for this reaction is 2HBr (aq) + 2NaOH (aq) → 2H2O (l) + 2NaBr (aq). This balanced equation represents the reaction between hydrobromic acid and sodium hydroxide to produce water and sodium bromide. Each side of the equation has the same number of atoms for each element.
If you used hydrochloric acid and metal would the reaction have been the same if you had used sulfuric?
Given the general equation:acid + metal ---> salt + waterSo, the only difference between a reaction with a metal and hydrochloric acid or sulfuric acid is the salt formed, a chloride and a sulfate respectively.
When limestone fizzes when acid is added is physical or chemical change?
The fizzing of limestone when acid is added is a chemical change. This is because a chemical reaction occurs between the acid and the calcium carbonate in the limestone, resulting in the production of carbon dioxide gas.
When a chemical reaction occurs the compounds remain the same as before the reaction?
During a chemical reaction, the atoms are rearranged to form new compounds. The original compounds are broken apart and recombined in different ways to produce new substances with different properties.
What is the gaseous substance produced in the chemical reaction of baking soda and acetic acid?
Carbon dioxide, the same gas you breath out in respiration.
Chemical reaction for potassium nitride?
It reacts with water to produce toxic Ammonia
If you start with 20 grams of hydrochloric acid how many grams of sulfuric acid will be produced?
Non!!!! They are two different substances/acids. The formulas for sulphuric acid is H2SO4 and for hydrochloric acid (HCl). With the exception of the hydrogens all the other elements present in the two difference acids are different.
What does an acid produce in water?
Simply a dilution of the same acid.
What is a substance that gives up hydrogen in a chemical reaction an alkali or a base oran acid or a metal?
A substance that gives up hydrogen in a chemical reaction is typically an acid. Acids are compounds that release positively charged hydrogen ions (H+) when dissolved in water. Alkalis, bases, and metals do not necessarily give up hydrogen ions in the same way.
Is acetic acid and acetic acid ester same thing?
No, acetic acid and acetic acid ester are not the same thing. Acetic acid is a simple organic compound with the chemical formula CH3COOH, while acetic acid ester is a compound formed by the reaction of acetic acid with an alcohol. Esterification of acetic acid forms esters, which are often used as fragrances or flavorings.
How do chemical reaction change substances?
After a chemical reaction, some of the bonds have been broken, and some new bonds have been formed. So, that's how a substance is changed after the reaction.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
