What is matter defined as?
Matter is anything that takes up space.
100
What do balanced chemical equations demonstrate?
It demonstrates the law of conservation.
100
Chemical formulas for an acid start with hydrogen or chloride?
They start with hydrogen.
100
Are molecular compounds made of non-metals or metals?
They are made out of non-metals.
100
The transfer of an element from sodium to chloride can be depicated by a lewis dot diagram. True or False?
It is true.
200
What is a mixture? Give an example
A mixture contains more than one kind of particle. Example: air
200
What are three forms in which chemical equations can be written?
Chemical equations can be written as a word equation, skeloton equation and balanced equations.
200
What four bases are ionic compounds, that have similar properties when dissolved in water?
1. Conduct electricity 2. Taste bitter 3. Feels slippery 4. Realeases hydroxide ions
200
What is combining capacity?
Combining Capacity is the number of bonds that can form a stable molecule.
200
What atoms gain and lose electrons?
Metals tend to lose electrons and non-metals tend to gain electrons.
300
What is a physical property?
A physical property is a characteristic of a substance that you can observe and measure without changing the substance.
300
What is the law of conservation of mass?
The law of conservation of mass is when the number of atoms of products are equal to the number of reactants.
300
Acids are?
They are a group of molecular compounds that have similar properties when it is dissolved in water.
300
What are the eight molecular compounds that use numerical prefixes when being named?
1. Mono equals one 6. Hexa equals six 2. Do equals two 7. Hepta equals seven 3. Tri equals three 8. Octa equals eight 4. Tetra equals four 5. Penta equals five
300
An ion is?
A ion is a charged atom in which the number of electrons is different from the number of protons.
400
What is a chemical property?
A chemical property describes the ability of a substance to react within another substance and form one or more new substances.
400
What are coefficients?
Coefficients are the numbers placed infront of a chemical formula to show how many units are involved in the reaction.
400
What different purposes are used for bases? Give an example.
Some acids are used to make cleaning products. An example would be sodium hydroxide, it is used to make hand soap.
400
What do you do whena prefix ending with a vowel is written with an element, that starts with a vowel. Give an Example.
When a prefix ends with a vowel and is written with an element that starts with a vowel you have to drop the vowel on the prefix. An example would be, tetroxide not tetraoxide.
400
When does ionic bonding occur?
Ionic bonding occurs when a metal transfers one or more electrons to a non-metal in an effort to attain a stable orbet of electrons.
