'cause alphe-particle which was +ve charge, get repulsion from the atom, so he deducted that.......
The number of moles that are 1.50 x10^23 molecules of NH3 are
=0.249 moles
<u><em> calculation</em></u>
The number of moles is calculated using Avogadro's law constant
that is According to Avogadro's law
1 moles of a substance = 6.02 x10^23 molecules
? moles = 1.50 x10^23 molecules
by cross multiplication
= [( 1.50 x 10^23 molecules x 1 moles) / (6.02 x10^23)] = 0.249 moles
Two animals that are omnivores are:
Bears and Badgers
Bears eat clover and other plants, and they eat salmon and other animals.
Badgers eat plants such as different fruits like pears and plums, and Badgers eat earthworms, insects, amphibians (such as frogs) reptiles and birds.
Answer:
NH₃ and H⁺
Explanation:
The dissociation of NH₄Cl will lead to two ions , i.e. , NH⁴⁺ and Cl⁻ .
Hence , the reaction is -
NH₄Cl → NH⁴⁺ + Cl⁻
We can conclude that NH₄Cl can be formed from the ions , NH⁴⁺ and Cl⁻
Hence ,
According to the reaction ,
NH⁴⁺ + H₂O ⇆ NH₃ + H₃O⁺
Therefore ,
The reactant that will lead to the formation of NH₄Cl are - NH₃ and H⁺
Answer:
Opposite pairs e.g. negative and positive. Because ions are charges atoms.
Explanation:
Ionic bond is a type of chemical bond where two atoms or molecules are connected to each other by electrostatic attraction.
A practical example is
Li+ and Br- pair. This so because they are unlike charges .
