A collision hypothesis that claims a chemical reaction can only happen when reactants collide at the right angle and with enough kinetic energy.
<h3>What in chemistry is a reactant?</h3>
A material that's also present at the outset of such a chemical reaction is known as a reactant. Products are the substrate(s) to the side of the arrow. A component that remains after a chemical reaction is finished is known as a product.
<h3>Which side are the products and reactants?</h3>
The chemicals (what you started with) be transformed into byproducts in a chemical process (what you end with). An arrow separates the reaction mixture, which are indicated on the left side of a solution, from the products, who are depicted on the right.

It is aluminium as it’s in the 13th group, which mean it has 3 valence electrons
Answer:
3.56x10^24 molecules
Explanation:
The following data were obtained from the question:
Mass of Na2SO4 = 840g
Molar Mass of Na2SO4 = (23 x2) + 32 + (16x4) =46 + 12 + 64 = 142g/mol
From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 molecules. This also gives that 1mole of Na2SO4 contains 6.02x10^23 molecules.
If 1 mole (i.e 142g) contains 6.02x10^23 molecules,
Therefore, 840g of Na2SO4 will contain = (840 x 6.02x10^23)/142 = 3.56x10^24 molecules
The protons contribute significantly more to an atom's mass because sodium has an atomic number of 11, where the number of protons in a neutral sodium atom is equal to the number of electrons. In the first group or column of the periodic table, sodium is an alkali metal.
The sodium atom mass has 11 protons and electrons, and its outermost shell has one valence electron. Pure sodium has a high level of reactivity. Since it is such a soft metal, a knife may be used to cut it with ease. The chemical element sodium has the atomic number 11 and the symbol Na.
