What elements make up Acetic Acid (vinegar) C₂H₄O₂?

Carbon, Acetic, oxygen, hydrogen

Are new elements created when a chemical reaction happens?

Sometimes, if Oxygen is involved

Most times, due to the use of heat

Are new substances created when a chemical reaction happens?

Most times, due to the reaction

Sometimes, if Oxygen is involved

What elements make up Sodium Bicarbonate (Baking Soda) NaHCO₃?

Sodium, Hydrogen, Carbon, Oxygen

Sodium, Hydrogen, Bicarbonon, Oxygenate

The Law of Conservation of Mass states that: Matter...

Constantly created and then destroyed

The number of components will ----- than the number of products.

All above are possible outcomes

In a reaction, what do you do with the mass of the container that the substances are in?

Count it in the before an after

At the beginning of a chemical reaction, you have 235 oxygen atoms. At the end of the experiment, you should have…

The same amount of oxygen atoms

No oxygen atoms, they were used up

While making popsicles, you use 10 grams of strawberries, and 50 grams of yogurt, stick a popsicle stick in it, and then let it freeze. When you weigh it, you notice the popsicle weighs 61.3 grams, when it should weigh 60 grams. What happened?

You did not account for the mass of the popsicle stick

Gravity pulls more on a solid, increasing the weight

The strawberries condensed, creating more mass.

Yogurt adds mass when it is frozen

A cat with the mass of 4,000 grams gets a haircut and rinse. When measuring its mass after, it weighs 4,200 grams. How is this possible?

The water left on it adds 200 grams

It was laying down, so it increased the mass by 200 grams

They took a collar off of the cat that weighed 200 grams

It was later in the day, so gravity increased its mass

While conducting an experiment, 40 grams of ice is melted into water. The end result is 38 grams of water. Which explanation is illogical?

When water is condensed the mass is greater resulting in a loss of mass when it turns into liquid form

Some of the water could have sweated through the cup, being lost in the final measurement

The lost two grams were gasses trapped in the ice and was released into the atmosphere

The water could have been spilled or lost when transferring to measure the mass

The following equation is balanced: 2HCl + 2Na → 2NaCl + H₂ Why isn’t there a “2” coefficient by the Hydrogen product?

The subscript means there are two Hydrogen atoms

You do not need two Hydrogens to make the equations balanced

You have to account for the other Hydrogens in the product

Hydrogen is exempt from the Law of Conservation

When looking at the products of a chemical reaction…

The number of atoms must be equal on each side of the equation

The number of products must be equal (2 reactants, 2 products)

The must be Hydrogen in the answer since it is the basic element

Must experience heat to create new products

Why is it important for a chemical equation to be balanced?

To ensure the same amount of atoms are present before and after the reaction

To keep explosions from happening, which could cause unaccounted atom loss

So that nothing iodized incorrectly

So that the subscripts add up to the total of the coefficients

When balancing a chemical reaction…

You can add coefficients to molecules

You can add to the subscripts to molecules

You can subtract the subscripts to molecules

You can add coefficients and subscripts to molecules
