Protons are positively charged particles found within the atoms nucleus. Protons were discovered by Ernest Rutherford in experiments conducted between the years of 1911 and 1919.

Neutrons are uncharged particles found within atomic nuclei. Neutrons were discovered by James Chadwick in 1932.

If 28.4 g of HgO decomposes and produces 2.0 g of oxygen, then 26 grams of Hg is produced.

<h3>What is decomposition reaction?</h3>

Decomposition reactions occur when complex chemical entities split apart into smaller components. Decomposition reactions often demand energy input.

There are three different kinds of breakdown reactions: thermal, photolytic, and electrolytic.

Mass_{reactant = Mass_{product}

Mass_{mercury oxide = Mass_{mercury} + mass_{oxygen}

28g =        mass_{mercury} + 2g

   mass_{mercury} = 26g

Thus, 28.4 g of HgO decomposes and produces 2.0 g of oxygen, then 26 grams of Hg is produced.

percentage mass_{mercury} = \frac{mass_{mercury}}{mass_{mercury}oxide}  X 100%

= 26g/28g

= 93%

thus  93% is the percent by mass of Hg present in HgO.

How much Sr(OH)2 • 8 H2O (M = 265.76) is needed to prepare 250.0 ML of solution in which [OH]= 0.100M?
SVEN [57.7K]
Use the formula 
first step: 
Use the formula 
molarity= mole/liter
change ml to l
plug in data
 to get .1=mole/.25 or .1M*.25liter
which =.025 moles
then divide .025 moles by two because there are two OH in Sr(OH)2 
then multiply that by 265.76 (the molar mass of water) 
.0125*265.76
which is 3.32grams this is your answer
