Answer:

Symbols: Each capitol letter means that there is a new element

Li2

Cl3

is made of lithium and chlorine

Na2

SO4 is made of sodium, sulfur and oxygen

Chemical Formulas are used to describe a chemical compound, when two or more atoms

combine to form a new substance.

A combination of chemical symbols shows the elements that make up a chemical compound.

The chemical formula for water is H2O

H stands for HYDROGEN.

O stands for OXYGEN.

Subscripts are numbers that come after a symbol and below. Subscripts tell you the number of

atoms of that element. If an element does not have a subscript, then it is understood that the

subscript is 1.

Li2Cl3 has two lithium atoms and three chlorine atoms

Na2SO4 has two atoms of sodium, one atom of sulfur, and four atoms of oxygen

A subscript outside a parenthesis affects all the elements inside the parenthesis. Multiply the

subscript on the outside by the subscript of the atoms on the inside.

Al (SO4)3 has 1 atom of aluminum, 3 atoms of sulfur, and 12 atoms of oxygen.

Coefficients are full size numbers in front of chemical formula. The coefficient multiplies everything

in the formula. It also represents the number of molecules of that compound.

2Na2

SO4 has 4 sodium atoms, 2 sulphur atoms, and 8 oxygen atoms.

2Al (SO4)

3 has 2 aluminum atoms, 6 sulfur atoms, and 24 oxygen atoms

When you count atoms, remember to multiply the coefficient number and the subscript number to find

the number of atoms of that element.

We gain energy from eating plants. Plants create energy. This statement is _____ according to the _____ law of thermodynamics.
aliya0001 [1]

Answer:

false, first

Explanation:

The first law of thermodynamics states that energy cannot be created or destroyed. Plants do not create energy, but rather they harness it from the sun. They convert the light energy in the photons of sunlight into chemical energy in the bonds of carbohydrates they make. We get energy from consuming plants when we acquire and break down these chemical bonds in carbohydrates of plants for our cellular processes.
