259 is the mass number of the isotope with the longest half life. This system is a convention from IUPAC for elements having very unstable and artificial isotopes.
Polar molecule charges are often written with parentheses to indicate the partial positive and partial negative charges associated with different atoms in the molecule. This notation helps clarify that these charges are not full ionic charges but rather represent a distribution of electron density. Using parentheses also visually distinguishes these partial charges from full ionic charges, aiding in the understanding of molecular polarity and interactions.
The charge it's written in parentheses with Roman numerals: Fe(II).
It is simply 101.000
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.
One thousandth of a meter is written as 0.001 meters in decimal form.
P(s) = s/t where success = s and total outcomes = t instead of a fraction it can be written as a decimal.
Parentheses are these marks ( )If you put something - like a plural noun - in parentheses, it just means you have written the word in between the marks. For example: (dogs)
If there are parentheses around the numbers (two parentheses for each number) multiply them.
1/10 is written, in decimal, as 0.11/10 is written, in decimal, as 0.11/10 is written, in decimal, as 0.11/10 is written, in decimal, as 0.1
No - they are identical numbers - 0.80 is just written to two decimal places instead of one.
It is already written as a decimal
