Because they believed that heavenly bodies’ circular motions where caused by their being attached to unseen resolving solid spheres
Yes, that is all correct!
The atomic number is the same as the number of protons (12).
Magnesium = Mg
Atomic mass is 24. 305.
Strong acids provide more H+ in the aqueous solution than the weak acids. This excess amount of H+ conducts more electricity in the solution.
Explanation:
The strong acid provides more H+ ion whereas the weak acids produce less H+ in the aqueous solution resulting in less amount of electricity conduction in the solution.
Weak acid- lesser amount of H+ produced
Strong acid- greater amount of H+ ( proton) produced.
A reagent us a chemical substance applied in a chemical reaction to bring about a change in the chemical reaction process. The reagent that is appropriate to carry out the conversion is Ethanol (CH3CH2OH).
Organic Reactions are reactions taking place in organic compounds and they can take various forms such as electrophilic addition reaction or nucleophilic substitution reactions.
From the assumed diagram below, the reaction takes place in an unimolecular nucleophilic reaction SN1 mechanism in which a racemic mixture produce an organic compound and an enantiomer.
For the reaction to take place, the best organic reagent to us is known as ethanol (CH3CH2OH). This is because the organic reagent is a solvent that acts as a Nucleophile.
In the reaction, bromine (Br) is the leaving group, after it detaches from the racemic compound, it forms a carbonation in which the Ethanol CH3CH2OH attacks at the carbonation site.
Therefore, we can conclude that the Reagent necessary to carry out the conversion is Ethanol (CH3CH2OH)

Dalton's atomic theory taught that all matter composed of atoms (inseparable and cannot be destroyed).
<u>Explanation:</u>
Dalton's atomic theory, the initiative comprehensive approach to explain all matter based on atoms and its properties. He proposed this theory based on the law of mass conservation and constant composition law. The importance of Dalton's atomic theory are:
Everything consists of atoms, which are inseparable elements of matter and cannot be impaired. All element's atoms are identical. Atoms of different elements differ in their sizes and masses. Compounds are created by simply bonding atoms and creating complex atoms (molecules).
