Answer:
You make each side equal to the other by muktiplying it by a number and yiu keep that number on each side. Hope this helps. :]
Explanation:
Answer:
39.998
Explanation:
Hello, have a periodic table handy!
Molar mass is the molecular weight of a compound; sum of all of the mass in grams (from the periodic table) from each and specific atom.
In the periodic table, the molecular weight of an atom is usually shown on the bottom of the element.
In NaOH, there are three atoms in that compound. Na (sodium), O (oxygen), and H (hydrogen).
For Na, the molecular weight is 22.99
For O, the molecular weight is 16.00
For H, the molecular weight is 1.008.
Add all of those values up together to get the molar mass of NaOH being 39.998
The answer is A mutualism
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For C and N,
E.N of Nitrogen = 3.04
E.N of Carbon = 2.55
________
E.N Difference 0.49 (Weakly Polar Covalent)
For N and S,
