Law of conservation of mass
What does it mean when something keeps its mass
Conservation of mass
What is the Ph of a neutral substance
7
A bug is walking in a deep puddle of water and isn't falling in
Matter that consists of only one type of particle with a fixed composition is known as this.
pure substance
Is the mass being conserved? There are more hydrogen atoms on the product side than the reactant side
If the Ph is 8 what is its classification
Base
This term describes the to different surfaces, such as water sticking to glass. What is it?
adhesion
A physical combination of two or more substances that can be separated by physical means is called this.
Mixture
According to this law, matter cannot be created or ____ in a chemical reaction.
True or False? A substance with a Ph of 3 is a Base
False
Water forming rounded beads on a freshly waxed car surface is caused by this property.
Cohesion
Saltwater is an example of this type of mixture, where the components are evenly distributed throughout.
Homogeneous Mixture
Is the mass being conserved?
C2H4 + H2O --> CH3CH2OH
yes
This type of substance turns blue litmus paper red and has a pH value lower than 7.
An acid
Water droplets clinging to a window after a rainstorm demonstrate this property.
Adhesion
Trail mix and salad dressing are examples of this type of mixture, where distinct parts are clearly visible.
Heterogeneous Mixture
These starting substances in a chemical reaction must equal the mass of the final products.
Reactants
This scale ranges from 0 to 14 and measures how acidic or basic a substance is.
The pH scale
ements and compounds are the two specific types that make up this classification
pure substance
