What else can I help you with?
Are all liquids able to be mixed to create solutions?
Not all liquids can be mixed to create solutions. Some liquids may not be soluble in each other due to their chemical structure and properties. Solubility depends on factors such as polarity, temperature, and pressure.
What is the diffrencence between exothermic reaction and chemical reaction?
A chemical reaction is a process that involves the breaking and forming of chemical bonds to create new substances. An exothermic reaction is a type of chemical reaction that releases heat energy to the surroundings. In other words, all exothermic reactions are chemical reactions, but not all chemical reactions are exothermic.
What identifies that a chemical reaction has occurred?
The most common indicators of a chemical reaction are: 1. A color change. 2. A temperature change. 3. Bubbles (indicating a gas) 4. A precipitate (a solid that settles out of liquids) A chemical change can feature all, none, or any combination of these.
Is melting of lead a chemical reaction?
No, melting of lead is a physical change, not a chemical reaction. A chemical reaction involves the breaking and forming of chemical bonds to create new substances, while melting only involves a change in state from solid to liquid with no change in chemical composition.
Dose a chemical reaction create molecules and compounds?
Yes, during a chemical reaction, existing chemical bonds are broken and new bonds are formed, resulting in the creation of new molecules and compounds. This process involves the rearrangement of atoms to form different substances with unique chemical properties.
Are all liquids the same?
No, all liquids are not the same. Liquids can have different properties such as density, viscosity, and surface tension which make them unique from one another. Additionally, liquids can have varying chemical compositions and phase states which further distinguish them.
What type of matter can exist in all three states?
Any chemical has that capacity, if you create the necessary conditions of temperature and pressure. All elements and all compounds can exist as solids, liquids, or gases.
Why does salt have to be added in a chemistry mixture?
That depends entirely on the chemical reaction that you may be trying to create. Not all mixtures require salt.
Are all liquids are able to be mixed to create solutions?
Not all liquids are able to be mixed to create solutions. Some liquids may not be soluble in each other and will separate into layers rather than forming a homogeneous mixture.
Is water a chemical reaction or a physical reaction?
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
What happens during every chemical reaction?
During every chemical reaction, chemical bonds between atoms are broken and new bonds are formed to create new substances. The total number of atoms of each element remains the same before and after the reaction, following the law of conservation of mass. Energy may also be absorbed or released during the reaction.
