What information does the chemical formula for a compound provide about the submicroscopic structure of the compound?
You can find out the elements in it, and the number of each ions of each element. Example : Na2SO4 (Sodium Sulfate) You can find out from this formula that this compound contains : 2 Sodium ions (Na2) 1 Sulfide ion (S) 4 Oxide ion (O4)
Is discharging a battery a chemical change?
When you use a battery the electric current is produced by a chemical change within the battery. In rechargeable batteries the chemical reaction is reversed by the recharging current, and it's then ready to supply more current
What information does a chemical formula provide about a molecule?
A molecular formula indicates the number and kinds of atoms in a molecule of the substance. For example, the molecular formula for water, H2O, indicates that each molecule of water contains two hydrogen atoms and one oxygen atom.
The chemical formula for an ionic compound represents the?
The smallest numbers of ions of the proper kind that provide a correct elemental composition for the compound with electrical charges balanced. For example, magnesium cations have a charge of +2 and chloride anions have a charge of -1, so that two chloride anions and one magnesium cation are required to provide electrical neutrality, resulting in a formula of MgCl2.
Is Mercury a pure compound?
Mercury is an element that is also a liquid. It is in the Periodic Table and is #80.
What evidence do fossils provide of the environments past and present?
changes in the environment e.g. the place, temperature, climate.
Why does archaeological evidence often fail to provide a complete picture about culture?
Archaeological evidence is limited by what has survived over time, which may not accurately represent the full diversity of practices within a culture. Additionally, biases in the preservation of certain materials can skew the archaeological record. Interpretations of evidence can also be influenced by the biases and perspectives of the archaeologists themselves.
Is skulls of human ancestors provide evidence of the anatomical changes that have occurred in hominids over time true?
Skull can provide an amazing amount of evidence of the anatomical changes that have occurred in hominids over time. Observations of the size of the skull can give us clues on how much the brain has evolved.
The magnetic particles in seafloor ridges are aligned differently in a repeating pattern How does this provide evidence for tectonic movement Why does it provide evidence?
Earth's magnetic field reverses over time; the changes show that seafloor has taken place over time.
Describe two other ways that rocks provide evidence of changes in th earth?
rocks provide changes in the earth by telling us that dinasours were alive before humans and we can tell this because the skeletons of dinasours are buried deeper than human skeletons.

Do chemical equations have no real structure?
Chemical equations provide the formulas of reactants and products in a chemical reaction. They usually do not provide structure unless supplemented with chemical structures.
What does provide evidence for continental drift?
Is there a list? Continental drift is real, so religious fanatics don't provide evidence for continental drift.
