What else can I help you with?
Why shouldn't you mix toilet cleaners together?
because they are two different chemicals and if you mix them together you can make a chemical reaction
Is melting salt a chemical reaction or physical reaction?
simply yes, because if you put them together, then the chemicals collide and therefore makes a chemical change.
What happens to temperature as volume decreases?
As volume decreases, the temperature of a gas tends to increase (assuming constant pressure) according to Boyle's law. This is because the gas molecules are more closely packed together, resulting in more frequent collisions that increase kinetic energy and thus temperature.
As you walk into the cold locker room the temperature of the helium inside your balloon decreases What happens to its volume?
The volume of the balloon decreases as the temperature decreases because the particles inside the balloon move more slowly and become more closely packed together, causing the balloon to shrink. This is because gases contract when they are cooled.
How can variables speed up or slow down a reaction?
Chemical reactions depend on the interaction of atoms and molecules with each other. Any change which will alter the frequency of such interactions occurring will alter the speed of the reaction. Temperature will affect the speed of a reaction, as will stirring or agitating the reagents together. The chemicals must also have enough energy available to reach the activation energy of the desired reaction in order to form the product. Catalysts are chemicals that speed up reaction time by lowering the activation energy without being consumed in the reaction themselves.
Is mixing chemicals a chemical reaction?
The act of mixing chemicals is a physical process, not a chemical reaction. Mixing chemicals together may, or may not, allow a chemical reaction to proceed, depending on the nature of the chemicals being mixed.
What is the result when you mix two different chemicals together?
- a chemical reaction with some chemicals as products - formation of a mixture
Hannah does an experiment. She has two colorless chemicals that she mixes together in a beaker. indicates that a chemical change occurs when she mixes the two chemicals together?
The formation of a colored solution when the two colorless chemicals are mixed together can indicate a chemical change. This change could result from a reaction between the two chemicals, leading to the formation of a new colored compound.
Why shouldn't you mix toilet cleaners together?
because they are two different chemicals and if you mix them together you can make a chemical reaction
What chemicals can be added to Coca-Cola to cause a chemical reaction?
Carbohydrates are added to the coca cola and mentos which react together to cause a reaction.
When the volume of an object decreases when the temperature decreases?
When the temperature of an object decreases, the particles have less kinetic energy, causing them to move closer together. This results in a decrease in the volume of the object, as the particles are occupying less space. This phenomenon is known as thermal contraction.
Is melting salt a chemical reaction or physical reaction?
simply yes, because if you put them together, then the chemicals collide and therefore makes a chemical change.
Is a mixture ever evidence of a chemical reaction?
Just because one has mixed chemicals together doesn't mean one will get a chemical reaction. The two chemicals could stay neutral when mixed. So, no just because a chemical is mixed it doesn't have to have a reaction.
What happens to temperature as volume decreases?
As volume decreases, the temperature of a gas tends to increase (assuming constant pressure) according to Boyle's law. This is because the gas molecules are more closely packed together, resulting in more frequent collisions that increase kinetic energy and thus temperature.
What are the chemicals called when they are mixed?
a solution is two substance mixed together
What statement is true about the temperature and desity of air?
As air temperature increases, its density decreases because the air molecules have more energy and move farther apart. Conversely, as air temperature decreases, its density increases because the molecules have less energy and come closer together.
What is the role of the bond in a chemical reaction?
For a reaction to occur between two chemicals, by definition a bond has to grow between them. They become bonded together and form a new product.
