Front

What is the arrangement of elements in the modern periodic table?

Back

The elements are arranged by atomic number.

Front

How do you calculate specific heat capacity?

Back

Front

What line segment represents only the solid state in a phase diagram?

Back

The line segment A-B represents only the solid state.

Front

What type of compounds are made from only nonmetals?

Back

Compounds made from only nonmetals are called covalent compounds.

Front

In an exothermic reaction, what happens to energy?

Back

In an exothermic reaction, energy is released to the surroundings.

Front

What is the definition of atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed by the transfer of electrons between metals and nonmetals, while covalent compounds are formed by the sharing of electrons between nonmetals.

Front

What does a phase diagram illustrate?

Back

A phase diagram illustrates the states of matter (solid, liquid, gas) of a substance at different temperatures and pressures.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat.
