the total is 100, since there is 85 the gas must be 15 g
You basically got it. They're called molecular compounds.
Salt dissolved in water forms a solution. A solution is a homogeneous mixture where the solute (salt) is evenly distributed in the solvent (water) at a molecular level. Each component retains its properties and can be separated through physical means.
Spaghetti and meatballs is a mixture, not a compound. A mixture is a combination of two or more substances that are physically combined without a chemical reaction taking place. In this case, spaghetti and meatballs are separate components that can be easily distinguished.
An example of a chemical reaction that absorbs heat is the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) to produce carbon dioxide gas. This reaction is endothermic, meaning it absorbs heat from its surroundings, causing the mixture to feel cold to the touch.
It is a solution. A solution is a type of mixture in which a solute is dissolved in a solvent. A solution is a homogeneous mixture. In the case of an aqueous solution of sodium nitrate, the sodium nitrate is the solute and the water is the solvent.
A mixture that produces a chemical reaction, scientifically speaking, is a chemical change.
Salt water is an example of a mixture. It is a solution made up of salt dissolved in water, without undergoing a chemical reaction. The components of salt and water can be separated by physical means such as evaporation.
These compounds doesn't react.
no.
Yes when you carry out any chemical reaction you will have some product at the end of the reaction. The things with which you start your chemical reaction is called reactants and the things which you get at the end are the products. For every chemical reation there is a product obtained and often catalyst are also used in it.
Yes, It is a mixture of water, and tealeaves. A chemical reaction does not occur.
Juice is not a reaction; it is a liquid mixture.
Chocolate milk is a mixture, as it is made by mixing chocolate syrup or powder with milk. It is not a chemical, compound, or a reaction.
a mixture is by definition not a chemical reactionA mixture is two or more substances which have been combined such that each substance retains its own chemical identity.So a mixture cannot be a chemical reaction, signs of a chemical reaction include:colour changeprecipitation (formation of a solid)effervescence (giving off gas)And every single chemical reaction involves gives of some heat.
These substances are called products in English.
When NaCl (sodium chloride) and KNO3 (potassium nitrate) are mixed together, no chemical reaction occurs as each compound remains as separate ions in solution. This is known as a physical mixture or a non-reactive mixture.
No. A slushy is a physical reaction. The mixture is frozen, therefore it is a physical reaction.
