Answer:
So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.
The number of moles of H₂ that are needed to react with 2.0 moles of N₂ is 6.0 moles
<u><em>calculation</em></u>
N₂ +3H₂→ 2NH₃
The moles of H₂ is calculated using the mole ratio
That is from equation above N₂:H₂ is 1 :3
therefore the moles of H₂ = 2.0 moles x (3/1) = 6.0 moles
Deforestation....trees release water vapour..with the trees being cut down less water vapour is being released..
consuming the water.... we use up water for drinking and for our homes etc...
hope this helps!
True
Explanation:
Ionic compounds are chemical compounds that dissociates into positive and negative ions and are globally neutral due to the charge balance. They are made up of metals and non-metals.
- Ionic bonds are formed between two kinds of atoms having a large electronegativity difference.
- It is usually between metals and non-metals.
- The formation of this bond type involves the transfer of electrons from the less electronegative atom such that the two kinds of atoms now have completely filled outer shell like the noble gases.
- This transfer makes the metal positively charged while the non-metal becomes negatively charged.
- The atoms forms ions that are oppositely charged.
- The charges are balanced out leaving a net neutral compound.
- The electrostatic force of attraction between these ions is the ionic or electrovalent bond.
