Chemical Change
Physical Change
Which of the following IS a chemical change
using chalk
water freezing
slicing cheese
digestion
The process by which one or more substances change to produce one or more different substances
Chemical Process
Reactant
Chemical Reaction
Some reactions require an input of energy in order to occur. Photosynthesis, the process in which plants use light energy to make sugars, requires an energy input. This reaction would be classified as .
endergonic
exergonic
synthetic
exothermic
When a wood fire burns, it releases heat into the environment. This type of
endothermic
exothermic
catalytic
endergonic
What are the reactants in the chemical equation pictured?
CH4 and CO2
CH4 and O2
CO2 and H2O
O2 and H2O
The Law of Conservation of Mass states
that matter exists in all states and reacts the same
that matter can only be changed into new substances by introducing a catalyst
that matter exists in the same state throughout any chemical change
that matter cannot be created or destroyed and that the mass of the products must equal the mass of the reactants
Why does this picture demonstrate the Law of Conservation of Mass?
the number of atoms of each element are the same on both sides
they start out separate and end up combined
the same elements are used
it doesn't demonstrate the Law of Conservation of Mass
At the end of chemical reactions, what is the total mass of the reactants compared to the total mass of the products?
the product is doubled
the product is half the mass of the reactants
the mass is the same
the mass changes depending on the reaction
10g of white powder reacts with 10g of clear liquid. The reaction bubbles and changes color producing a black liquid that has a mass of 13g. What can be concluded?
5g of gas was produced
This experiment violates the conservation of mass
7g of gas was produced
The excess reactant is destroyed & disappears during the reaction
A molecule made of 2 atoms is called a ____________________.
Diatomic Molecule
Chemical Bond
Product
Reactant
What type of reaction involves the breaking down of a substance into simpler substances?
Single Displacement Reaction
Double Displacement Reaction
Synthesis Reaction
Decomposition Reaction

A) Energy production
B) DNA replication
C) Protein synthesis
D) Cell signaling
In an experiment, Ms Ps1 6 is observed to interact with a specific enzyme. What is the likely outcome of this interaction?
A) Inhibition of the enzyme
B) Activation of the enzyme
C) No effect on the enzyme
D) Degradation of the enzyme
Ms Ps1 6 is found to be crucial in a particular signaling pathway. Which of the following best describes the role of signaling pathways in cells?
A) They provide structural support to the cell
B) They facilitate the transport of molecules across the cell membrane
C) They transmit information from the cell surface to the interior
D) They are involved in the synthesis of cellular components
