Question 4 (2 points) Potassium chlorate decomposes into potassium chloride and oxygen gas according to
the following equation:
2 KClO3 --> 2 KCl + 3 O2
Use the equation above to answer the questions that follow:
How many grams of potassium chloride will be produced from the decomposition of
4.00 moles of oxygen?
Do not put the answer in scientific notation. Do not include the substance as part of
your unit. Units should be all lowercase letters and singular (not plural) and no
spaces among units. You will choose from the following units:
В
g/mol
mol

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
