Geologic time begins with a very long span called Precambrian Time. Precambrian Time ended about 544 million years ago. Scientists have organized geologic time into chunks. The chunks of time span different lengths. Using the model, organize the basic units of geologic time in order from longest to shortest.

When balancing a chemical equation:

Which of the following is a conclusion that resulted from ernest rutherford’s scattering experiment? (will mark brainliest) a. the nucleus is negatively charged b. the atom is a dense solid and is indivisible c. the mass is conserved when atoms react chemically d. the nucleus is very small and the atom is mostly empty space

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )
