Making a pancake from batter is an example of blank change
lesantik [10]

Answer is: chemical.

Making a pancake from batter is chemical change (chemical reaction), because new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.

Batter is thin dough that is poured into a pan to make pancakes.

In physical change, the same substance is present before and after the psysical change, just with different form or state of matter.

Copper has a density of 8.96 g/cm3. If a thin sheet of copper measures 5.5 cm by 5.5 cm and has a mass of 12.96 g, what is its t
balandron [24]

Thickness of cooper sheet is 0.048 cm (Approx.)

Given that;

Density of copper = 8.96 g/cm³

Measures of copper sheet = 5.5 cm × 5.5 cm

Mass of of copper sheet = 12.96 gram

Find:

Thickness of cooper sheet

Computation:

Volume = Mass / Density

Volume of cooper = 12.96 / 8.96

Volume of cooper = 1.4464

Volume of cooper = 1.45 cm³ (Approx.)

Volume of cooper sheet = 5.5 cm × 5.5 cm x Thickness

5.5 cm × 5.5 cm x Thickness = 1.45

Thickness of cooper sheet = 0.04793

Thickness of cooper sheet = 0.048 cm (Approx.)

What is a chemical formula?
krek1111 [17]

Answer:

A. An identification of the atoms in a molecule

Explanation:

The chemical formula of a compound is a representation which shows all the elements therein and the mole relationship between them expressed as subscripts.

Therefore, a chemical formula allows us to identify atoms that are within a molecule.

A molecule is a covalent compound that has discrete or separate units.

For example;

         HCl represents 1 mole of hydrogen chloride molecules consisting of 1 mole of hydrogen atoms and 1 mole of chlorine atoms.
