Two solutions are mixed and react to produce AgCl. The chemical reaction is shown below by the balanced equation. AgNO₃ + LiCl → AgCl + LiNO₃ What happens to the total mass as the reaction takes place?

A pool was tested using a pH strip as seen below. What is the current pH of the pool and what does this tell us?

What elements are involved in this chemical reaction? CaCO₃ → CaO + CO₂ There are more than one answer.

In the chemical reaction, HCl (acid) + NaOH (base) → H₂O + NaCl, what elements are involved and what is produced by the reaction?

As noted in the book, chlorine tablets are used in swimming pools to maintain the health of the water and the pH levels. The main reaction is: Cl₂ + H₂O → HOCl + HCl Which components are reacting as elements, compounds or mixtures? Click all that apply.

Droplets of water remain on the lower side of this leaf, even though gravity pulls the water downward. What property of water keeps the drops of water from falling to the ground?

Adhesion, cohesion, and surface tension are properties that are observed in water. What unique property of water molecules makes adhesion, cohesion, and surface tension possible, AND why are adhesion, cohesion, and surface tension observed in liquid water but not in ice?

A student used pH test strips to determine the pH of some common household items. She recorded them in the table below. Which items in the table are classified as acids?

In a lab demonstration, a teacher burned a strip of magnesium ribbon in a crucible that was inside a fume hood. The chemical equation for the reaction that occurred is: Mg(s) + O₂(g) → 2MgO(s) The masses of the reactants and products of the combustion reaction are shown in the table. Assuming that the combustion reaction was complete, what mass of oxygen reacted with the magnesium ribbon?

The chemical equation for photosynthesis shows that the products are sugar and oxygen gas. 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ The sugar that is a product of this reaction has a total number of ______ Carbon, ______ Hydrogen, and ______ Oxygen atoms per each molecule. This is classified as a/an ______?

A student measured a vinegar solution into a beaker and then added 8.4 g of baking soda to the solution. The reaction between vinegar and baking soda formed water and sodium acetate, which remained in the solution. The reaction also formed carbon dioxide, which was released into the atmosphere as a gas. The measurements of the reactants and remaining products of the reaction are shown in the table. Assuming a complete reaction occurred, and based on these measurements above, what mass of carbon dioxide was released into the atmosphere?

A student was given an unknown material and performed experiments to determine the nature of the material. The material was identified as being either an acid or base solution. The student recorded these observations about the solution. I. The solution conducts an electric current. II. When a drop of the solution is placed on a zinc strip, bubbles form. III. The solution is a clear, colorless liquid. Which observations provide evidence that could be used to determine whether the material is an acid or a base?

The pictures below were taken of Reginald the Robot before and after he got stuck outside in the rain. What has the rain most likely done to Reginald?

The model below shows the composition and arrangement of atoms in a beaker. What is the classification of the material in the image of the model above?

Which type of change must occur to form a compound?

The mass of the new product is ______ grams.
