Balancing equations
Why should equations be balanced?
To keep from breaking the law of conservation of mass
What are the things called that make the products?
What is Reactants?
How many types of chemical reactions are there?
5
What is energy made of?
The capacity to preform a task
how to slow down the reaction rate
by doing any or the variables
what is the first step of balancing a chemical equation?
What is counting the atoms on each side of the equation.
What is a chemical reaction?
What is a chemical reaction is a process that occurs when two or more molecules interact to form new products?
What is decomposition?
When 1 reactant breaks down into 2 or more products.
Do all chemical reactions use energy?
Yes
How does raising the temperature effect the reaction rate
By heating up the substance it causes the particle to move faster, causing more collision and makes them react more
What steps do you repeat when balancing equations?
Steps 2 & 3
The number of each substance needed?
what is a coefficient?
What are the 5 types of chemical reactions?
Synthesis, Decomposition, Combustion, Single- replacement, & Double-replacement
What are the two ways that chemical reactions use energy?
Absorbing and Reliquishing
What dissolves faster flaky salt of normal table salt and why
normal table salt as it has more surface area
How many steps are there for balancing equations?
4
When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an _________ as new products are generated.
What is an energy change
What type of chemical reaction the Elephant Toothpaste
Decomposition
What are the four types of energy mostly used?
What is light, heat, electricity, and gas?
What is the unofficial 6th way off changing a reaction rate
trick question there is none tehe
Balance the equation
C4H10+O2→CO2+H2O
What is 2C4H10+13O2→8CO2+10H2O
Carbon (C): 8 on both sides
Hydrogen (H): 20 on both sides
Oxygen (O): 26 on both sides
Name 4 examples of chemical reactions
what is photosynthesis ,combustion ,decomposition ,oxidation,digestion,rust,respiration,precipitation etc.
What type of chemical reaction is occurring here
H2CO3(aq)→H2O+CO2(g)
Decomposition
What are the 4 types of chemical reactions that use energy?
What is exergonic, exothermic, endogenic, and endothermic?
what are the 5 factors that affect the rate of a chemical reactions?
What is Temperature, Concentration, Surface Area , Catalysts and Pressure
