Would it be OH2 or parentheses OH parentheses 2 for two hydroxides?
Two hydroxide ions would best be written as 2 OH-1 in an ionic equation, rather than either of the alternatives given in the question. If the two hydroxide ions occur together with a divalent cation such as magnesium in a compound, then the hydroxide ions would be written as (OH)2. Two ions should never be written as OH2, because that is the formula for water, with the ions in an unconventional order, rather than the formula of ions at all.
How many DM are in 400 MM?
400 millimeters = 4 decimeters Edit: Remember that the units for decimeters and millimeters are written in all lower case letters (dm and mm). A capital M mean mega- instead of milli- which means the decimal point can be 12 places too far to the left or the right.
When do you use a parentheses for a formula?
When there is more than one polyatomic ion. Calcium Hydroxide is an example. Ca has a charge of 2+ and OH has a charge of 1-. To make this neutral, 2 hydroxides are required. So it would be written: Ca(OH)2. If we didn't use the parentheses, it would look like there was 1 calcium, 1 oxygen, and 2 hydrogens. Obviously this isn't right. That's why the parentheses are necessary.
