The equation is H2SO4 + 2NaOH = 2H2O + Na2SO4, Also, what is the theoretical yield of Na2SO4 in grams?
To answer this question, you need to know the Avogadro number. To find the amount of sugar molecule from mol unit you need to multiply it by the Avogadro number.
The calculation should be like this: <span>0.734 mol * 6.02*10^23 molecule/ mol= 4.41 * 10^23 molecule</span>
Answer: Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction.
Explanation:
Dalton's Atomic Theory was proposed in the 20th century by an English Scientist named John Dalton. His theory is postulated as follows:
1) All elements are composed of tiny indivisible particles called atoms.
2) The atoms of any one element are identical to those of any other element. 3) Atoms of different elements can physically mix together or can chemically combine in simple whole-number ratios to form compounds.
However, the final option is NOT one of Dalton's Theory
Answer:
The critical chemical difference is that CO2 contains one atom of carbon and two atoms of oxygen, whilst CO has one carbon and one oxygen atom.
Answer:
The correct answer is - nuclear fission.
Explanation:
In the given diagram, the reaction is a graphical representation of the nuclear fission of one nucleus of Uranium 235 into two nuclei of Kr with three neutrons that leads to a chain reaction and releases a huge amount of energy and grow out of control.
With every fission, there are two neutrons emitted which results in splitting more nucleus into two nuclei and keep on growing and never die out. The amount of energy also keeps on growing with an increase in the reactions and fission. This reaction is used to generate electricity and nuclear weapons.
