There are 3.75 moles of oxygen in a 1.25 mol sample of CaCO₃.
Limestone is primarily a crystal form of CaCO₃ (calcium carbonate). According to its chemical formula, the molar ratio of CaCO₃ to O is 1:3. The moles of oxygen in 1.25 moles of CaCO₃ are:
There are 3.75 moles of oxygen in a 1.25 mol sample of CaCO₃.

As the molecular formula of CaCO₃ suggested, that there are 3 moles of oxygen are there in 1 mole of CaCO₃.
So in 1.25 mol of CaCO₃ contains=1.25 ×3 moles of oxygen
=3.75 moles of oxygen
So there are 3.75 moles of oxygen are there in 1.25 mol of CaCO₃.
Answer:
Applied science is generally engineering, which develops technology, although there might be dialogue between basic science and applied science (research and development). Medical sciences such as medical microbiology are examples of applied sciences.
Explanation:
'Heavy' hydrogen (the isotope deuterium) , 2/1H is involved ,
[2= mass number, 1= atomic (proton) number]
2/1H + 2/1H → 3/2He + 1/0n
b. 2
c. 3
d. 4
Cold liquids have more electrons.
Particles in hot liquids move faster than particles in cold liquids
Particles in cold liquids move faster than particles in hot liquids.
Particles in hot liquids move faster than particles in cold liquids. The faster a particle moves, the greater its kinetic energy.
The number of electrons in a particle has nothing to do with its kinetic energy.
Particles in cold liquids move more slowly than particles in hot liquids.
