Hi!

We make sure data is reliable by repeating it over and over and over and over and over again! 

Repetition and replication <span>are </span>key, as the most constant consistent results we get - the more reliable the data is!

Hopefully, this helps! =)

What is the dot-and-cross diagram for magnesium chloride (MgCl2)??​
Andrei [34K]

Answer: Lewis dot structures aren't drawn for ionic compounds, such as MgCl2. Because there aren't any shared electron pairs in an ionic compound. Lewis structure are only drawn for molecular compounds, atoms, or some individual ions. If we want to visualize a chloride ion (Cl -), it's Lewis structure will show Cl with complete octet.

Explanation: Hope this helps you

How many moles of H2O2 are needed to react with 1.07 moles of N2H4?
I am Lyosha [343]

Answer:

2.14 moles of H₂O₂ are required

Explanation:

Given data:

Number of moles of H₂O₂ required = ?

Number of moles of N₂H₄ available = 1.07 mol

Solution:

Chemical equation:

N₂H₄  +   2H₂O₂       →   N₂ +  4H₂O

now we will compare the moles of H₂O₂ and N₂H₄

                          N₂H₄     :      H₂O₂  

                            1           :        2

                            1.07      :         2×1.07 = 2.14 mol
