1) For example, sodium oxide (Na₂O).

One one molecule of sodium oxide has one sodium atome (Na) and two oxygen atoms (O).

The subscript after element shows the number of elements in a molecule.

2) Yes, it possible for two different compounds to be made from the exact same two elements.

This are isomers, same molecular formula, but different arrangements of atoms.

For example, n-butane (C₄H₁₀) and 2-methylpropane (C₄H₁₀).

3) There are large number of compounds in this world, around 40 millions.

The reaction between calcium carbonate (CaCO3) and HCl produces calcium chloride (CaCl2), carbon dioxide (CO2), and water (H2O).

Aleks [24]

The given chemical reaction is between calcium carbonate and hydrochloric acid to produce calcium chloride, carbon dioxide and water. This reaction can be represented as,

$CaCO_{3}(s) + 2HCl(aq)-->CaCl_{2}(aq)+H_{2}O(l)+CO_{2}(g)$

When the concentration of the reactants is increased, the number of collisions that take place between the reactant molecules increases. This speeds up the reaction. Therefore, when the concentration of HCl is doubled as long as there is enough calcium carbonate to react with HCl, the number of effective collisions giving products increases, this causes the rate of forward reaction to increase.

which idea did john dalton include in his atomic theory? a. all atoms are the same size. b. atoms of the same element are identi

lapo4ka [179]

It might be c, because he came up with the plum pudding model. or it might be that atoms of the same element are identical, but that's not true cuz ions are different and isotopes are different.
