"A" is the answer. The chemical reaction is when the batter becomes brown.
B is mixing C is mass becoming a liquid and D. is dissolving no chemical reaction happened there.
Hope that helps!
because iodine is an atom and it can permeate the pores of the plastic bag.
Hello!
Graphs are used to understand an object's motion because they can show the exact location of the object at any given moment.
This is done with the help of a reference system. The most common reference system is the Cartesian coordinate system, which describes the location of an object through a set of 2 or 3 coordinates (depending if the system is in 2D or 3D).
Studying graphs of movement, we can know if the movement is cyclical, or the direction of the movement, determine tendencies and overall getting an unambiguous and precise understanding of the motion.
Have a good day!
False: I believe if two atoms are in the same group it would not mean they have the same number of electron shells BUT it would mean that if the two atoms are in the same group they would have the same number of valence electrons.
Hoped this helped :)
The electrons move<span> around the protons, which are at the center of the atom. </span>How does the energy of an electron change when the electron moves closer to the nucleus<span>? ... When an </span>electron moves<span> from a lower to a higher </span>energy<span> level, the</span>electron<span>...</span>
