The Equation of reaction
C + O2 === CO2
First Blank spot would be
---- 3.5moles of O2
2nd spot
Up.... 1mole of CO2
Down ---- 2moles of Oxygen atoms
3rd spot
Up... --- 22.4L of CO2(1mole of any gas at STP contains 22.4L)
Down---- 1mole of CO2
Final answer --- 3.5 x 1/2 x 22.4
=39.2L of CO2
Molar mass of CeCl3 = 246.475 g/mol
This compound is also known as Cerium(III) Chloride.
Convert grams CeCl3 to moles or moles CeCl3 to grams
Molecular weight calculation:
140.116 + 35.453*3
Answer:
Explanation:
Hello.
In this case, we can solve this problem by applying the Boyle's law which allows us to understand the pressure-volume behavior as a directly proportional relationship:
In such away, knowing the both the initial pressure and volume and the final volume, we can compute the final pressure as shown below:
Consider that the given initial pressure is also equal to Pa:
Which stands for a pressure increase when volume decreases.
Regards.

Explanation:
Big Bang: During the big bang, elements were formed by the squeezing together of light nuclei. Hydrogen atoms were fused together to make helium, lithium and other light weight elements.
Stellar Nucleosynthesis: Stellar nucleosynthesis is the process by which elements are created within stars by combining the protons and neutrons together from the nuclei of lighter elements(Thoughtco). In the stars, hydrogen may be fused to give helium, lithium and other elements lighter than iron.
Supernova Nucleosynthesis: A supernova is a process in which a star releases a large amount of energy together with neutrons, hence elements that are heavier than iron, like uranium and gold, can be produced in the process.
Answer:
Electrons are the smallest of the particles that make up an atom, and they carry a negative charge. The number of protons and electrons is equal in a neutral atom. The hydrogen atom, for example, has just one electron and one proton. The uranium atom, on the other hand, has 92 protons, and therefore, 92 electrons.
