Answer: Electrovalent or Ionic Compounds
Explanation:
Electrovalent Compounds Form bonds that are characterised by transfer of electrons from metallic atoms to non-metal licenses atoms during a chemical reaction.
The metallic atom after donating their valence electrons, become positively charged, while the non-metal license atoms becomes negatively charged after acquiring extra electrons.
A typical example of electrovalent compounds can be found between the association of Group 1(Alkali Metals) elements and the Group 7(Halogen Family) elements.
c. 1.5 moles of Cu will contain a total of 9.0 * 10 ^ 23 atoms.
Explanation:
To convert moles into atoms, the molar amount and number of atom is multiplied by Avagadro's number.
Avagadro's number is 6.022×
So applying the formula in the given sample:
A) 0.5×6.022×
3.01× atoms.
B) 0.75 mole of H20
O.75×6.022×
= 4.5166× atoms.
C) 1.5 moles of Cu
1.5×6.022×
= 9.033×
D). 1.5 moles of H2
1.5 × 2 × 6.022 ×
= 18.066 × atoms because H2 is 2 moles of hydrogen.
Atom is the smallest entity of matter having property of the element to which it is a part.
The scientific method is defined as a method of research in which a problem is identified, relevant data is gathered, a hypothesis is formulated from this data, and the hypothesis is empirically tested.
Answer:
The answers to your question are given below
Explanation:
The equation for the reaction is given below:
2KClO₃ —> 2KCl + 3O₂
The total number of each atoms present in the reactants and products can be obtained by doing a head count as illustrated below:
Reactants >>>>>> Number of atoms
Potassium (K) >>> 2 × 1 = 2
Chlorine (Cl) >>>> 2 × 1 = 2
Oxygen (O) >>>>> 2 × 3 = 6
Products >>>>>>> Number of atoms
Potassium (K) >>> 2 × 1 = 2
Chlorine (Cl) >>>> 2 × 1 = 2
Oxygen (O) >>>>> 3 × 2 = 6
