A chemist mixed two substances together: a blue powder with no smell
and a colorless liquid with a strong
smell. Their repeating groups of atoms
are shown above on the left. After they
were mixed, the chemist analyzed the
results and found two substances. One
ending substance had the repeating
group of atoms shown above on the
right.
Is the ending substance the same
substance as the blue powder? What
happened to the atoms of the starting
substances when the ending
substances formed? Be sure to explain
your answers to both of these

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
