What is the net ionic equation
2 H^+ + SO4^2- + Ca^2+ + 2 i^- = CaSo4 + 2H^+ +2i ^-
cancel the spectator ion that is the ions which does not take place nin the reaction
for this case is 2 H^+ and 2 i^-
the net ionic equation is therefore
=Ca^2+ + SO4^2- = CaSO4
The correct answer is False
It's B. by identifying the elements.
Reasons:
prefixes are only used for covalent compounds.
You don't include the number of atoms when you write the chemical name of a compound.
Subscripts are basically numbers that tell how many atoms of each element is in a compound. It does not identify the name of an element.
Answer:
It indicates phase changes:<em> melting then later boiling.</em>
Explanation:
On the heating curve of water, the plateau marks phase change transitions.The temperature remains constant during this period.The first phase change is melting of water.The second phase change is boiling of water to gas.
