Phillip watches a burning log in the fireplace. He makes these observations:
I. .The fire gives off heat.
II. There is a strong smell of smoke
III. Light is emitted where there are flames
IV. Ashes form from the logs.
V. Heat waves appear in the air above the log
Which of Phillip’s observations are conclusive evidence that the burning log undergoes chemical changes and not just a physical change?
observations I, II, and V only
observations II , III, and V only
observations II, III, and IV only
observations I, III, and V only
Type any one of the standard possible endings of a for polyatomic ions
(a)
When a Bunsen burner is lit; why is the presence of a flame considered to be an indication of a chemical reaction?
A flame indicates a change of energy.
A flame indicates a change in chemical energy and phase change.
A flame indicates new physical energy is forming.
A flame indicates a change in chemical energy.
The reaction represents a chemical change because the rust is just a mixture of water and iron.
The reaction represents a chemical change because the iron oxide is a new substance and has a different melting point than iron.
The reaction represents a chemical change because both the original cannonball and the rusted cannonball are solids.
The reaction represents a chemical change because iron oxide is a new substance formed on the cannonball.
Parts of the atom include positive particles called (a) , neutrons which have a (b) charge and electrons that have a (c) charge. The protons and neutrons are located in the (d) . The (e) are not allowed in the nucleus so they stay in the energy levels.

Which element can combine with K to form a neutral ionic compound? (Type the symbol of one of the possible correct answers)
(a)
The Name of this element is (a) . It is in period (b) and group (c) . It has a mass of (d) and will have a charge of (e) because it is a metal and metals lose electrons
