What else can I help you with?
What are the materials you have at the beginning of a chemical reation?
products
What is the original substances before a chemical reation occurs are the?
Reactants --> Chemical reaction --> Products
The acidbase numbering sytem?
1-14
What is an endothermic reation?
A reaction that absorbs energy making the products feel cooler (the temperature decreases over time)
Does an exothermic reation release energy into its surroundings and its products have more energy to the reactant?
Two different answers:Yes, an exothermic reaction releases energy into its surroundings No, its products do NOT have more energy than the reactant(s)
When this reation occurs in a lab the room gets warmer and light is given off. is the reation exothermic or endothermic?
122
Is frying an egg a chemical reation?
no
What will speed up a chemical reation?
Catalyst
What is the product of sodiums reation with water?
water
What are the new substances that are formed during a chemical reation?
New substances formed during a chemical reaction are called products. These products are different from the original reactants and may have different physical and chemical properties. The formation of products results from the rearrangement of atoms and the breaking and forming of chemical bonds during the reaction.
Which term is defined as new substances formed from chemical reation?
The term defined as new substances formed from a chemical reaction is "products." During a chemical reaction, reactants undergo transformation to create these products, which have distinct properties and compositions compared to the original substances.
Examples of primary standards used in acidbase titrations?
Oxalic acid,sodium oxalate or ammonium iron (II) sulfate.
