It is typically formed by the evaporation of salty water (such as sea water) which contains dissolved Na+ and Cl- ions. One finds rock salt deposits ringing dry lake beds, inland marginal seas, and enclosed bays and estuaries in arid regions of the world
The mass of one Au atom is 196.97 amu from periodic table and the mass of Avogadro's number of Au atoms is 196.97 g due to this is the mass of one mole of gold
There are 55 carbon 72 hydrogens 1 magnesium 4 nitrogen and 5 oxygen
so that would be 55+72+1+4+5
and that is 137
Answer:
The Kuiper Belt is a region beyond Neptune that is 55 astronomical units (AU) from the Sun. It contains smaller bodies that scientists think are pieces left over from the formation of the Solar System. Which of the following best states how scientists know that the Kuiper Belt is part of our solar system?
Answer:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
Explanation:
Sodium hydroxide (NaOH) is a <u>strong base</u> and hydrochloric acid (HCl) is a <u>strong acid</u>. That means that they are totally dissociated into ions in aqueous solution.
When a solution of NaOH is mixed with a solution of HCl, a neutralization reaction occurs, in which a salt (NaCl) and water (H₂O) are formed.
The <em>balanced molecular equation</em> for this reaction is:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
