Answer:
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
Explanation:
Word equation - calcium + oxygen -> calcium oxide
Chemical equation - Ca + O2 -> CaO2

At STP condition 1 mol of any ideal gas will have a volume of 22.4L
1.75 mol of F2 x 22.4 L / 1 mol = 39.2 L
12 moles of oxygen gas are needed to react with 24 moles of carbon monoxide.
<u>Explanation:</u>
The molar ratio of carbon monoxide to oxygen 2:1
Which means 2 moles of carbon monoxide is reacting with 1 mole of oxygen.
to produce 2 moles of carbon dioxide.
Therefore, from the molar ratio, we get that 12 moles of oxygen are required to react with 24 moles 0f carbon monoxide.
Molar ratio:
The molar ratio gives the moles of product that are formed from a certain amount of reactant, and also the number of moles of a reactant needed to react with another reactant.
In order to balance this, you have to count each
element where the elements in the reactants side and the product side should
have equal number of molecules. The balanced reaction is as follows:
2HCl + Ca(OH)2 = CaCl2 + 2H2O
