Are there any compounds on the periodic table?

no because only elements are on the periodic table

Suppose a reaction were to happen in an open container in a lab. During the reaction, the scientist observes the chemicals bubble, and produce a gas. During the analysis the scientist notices that the reactants weighed 20 g when he started, and the product weighed 18 g. Explain what happened.

The gas that was produced was not able to be weighed since the container was open.

His chemical reaction defied the law of conservation of mass

The product destroyed mass during the reaction

The reactants created matter during the reaction

Why does this picture demonstrate the Law of Conservation of Mass?

the number of atoms of each element are the same on both sides

they start out separate and end up combined

it doesn't demonstrate the Law of Conservation of Mass

In a closed system, a chemical reaction takes place. The mass of the reactants in the beginning of the reaction is 25g. What does the mass have to be in the end of the reaction in order to follow the law of conservation of mass?

You can't tell with the given information.

When CaCO 3 is heated, it forms CaO and CO 2 . Which of these statements best describes the mass of the products if 100 g of CaCO 3 is heated?

The sum of the products’ masses equals the mass of the CaCO 3

The difference in the products’ masses is equal to the mass of the CaCO 3

The sum of the products’ masses is less than the mass of the CaCO 3

The mass of each product is equal to the mass of the CaCO 3

10 g of a solid chemical reacts with a 10 g of a liquid chemical, the reaction bubbles and changes the color of the liquid. The colored liquid weighs 13 g, what can be concluded?

The gas produced from the bubbles weighed 5 g

The bubbles were evidence of 7 g of matter being destroyed

The formula below represents the most common carbohydrate known as glucose. Which information can be determined from the chemical formula? C 6 H 12 O 6

The number of atoms of each element in a glucose molecule

The structural arrangement of the atoms in a glucose molecule

The color of a glucose molecule
