Tag the questions with any skills you have. Your dashboard will track each student's mastery of each skill.
Which statement about the molecules in ice and the molecules in liquid water is correct?
A hot air balloon rises because
The solid, liquid, and gaseous states of water differ from each other in
Based on the melting points shown in the table which material would still be a solid at 400oC?
A(n) _______________ is a bond formed when many metal atoms share their pooled valence electrons.
A chemical bond that occurs when atoms share electrons is a(n) ______ bond.
What is the name of a binary compound made up of lithium and chlorine?
What kind of chemical bond is formed when electrons are transferred from atom to atom?
During science lab, some students added small pieces of magnesium (Mg) to hydrochloric acid (HCl). They noticed that bubbles formed, the test tube got hot, and the magnesium disappeared. Which of the following is a sign that a chemical reaction has taken place in this experiment?
Two or more atoms joined covalently, that act as a unit are called a(n)
A group of students were asked to identify three white powders. The students used physical and chemical properties to identify the powders. They computed the density of each powder. They checked to see if any dissolved in water. One of the powders did not dissolve in water and they thought it was cornstarch. They knew that cornstarch felt slippery and reacted with iodine. The students put a few drops of iodine on each white powder. One powder turned black; it was definitely cornstarch. Another powder, baking soda reacted with vinegar. It fizzed and the test tube got hot.
Which of these is an observed chemical property?
As you move across the periodic table from right to left within a period, the elements
Using the Law of Conservation of Matter, determine the number of grams of iron sulfide (FeS) that will be produced in this reaction.
The bulb of a thermometer is placed in your mouth. Which of the following explains why the level of the liquid rises in the thermometer?
The element nickel has five naturally occurring isotopes. Which of the following describes the relationship of these isotopes?
Wood and oxygen are commonly burnt at campfires and all that's leftover is ash and char. What is the BEST conclusion about this chemical reaction?
A solubility curve for potassium nitrate (KNO3) is shown.  According to the graph, what is the maximum approximate mass of KNO3 that would dissolve in 60oC and what is the relationship between temperature and solubility?
The elements neon and argon are not reactive. Which hypothesis BEST explains this?
Using the Periodic Table, what is the correct model of chlorine (Cl)?
A student is modeling the units in the formula for aluminum sulfide using the spheres shown below to represent aluminum (Al) and sulfur (S) atoms. Â
Which model correctly shows a stable ionic compound for aluminum sulfide?
