Answer:lanthanides is the answer and here is a picture for proof
Explanation:
Golgi apparatus because it packs vesicles and transports them to the parts of cell where they are needed.
Hey there!
Atomic mass Bromine ( Br ) = 79.9 u
Therefore:
79.9 g Br --------------- 22.4 L ( at STP )
18.0 g Br --------------- volume ??
Volume Br = 18.0 * 22.4 / 79.9
Volume Br = 403.2 / 79.9
Volume Br = 5.046 L
hope this helps!
At the end of the reaction, the catalyst is UNCHANGED.
