Hello!
When finding the chemical formula of a compound, we will need to find the charges of each element/bond.
Looking at our period table, sodium has a +1 charge, written as Na 1+, and sulfate has a charge of -2, and it is written as SO4 2-.
Now, we need to make the charges equivalent. To do this, we need to "criss-cross" the charges. This means that sodium will need to additional atoms to make the charges equal, and sulfate will need one.
Therefore, the chemical formula for sodium sulfate is: Na2SO4.
27*9=243 if one mole is equal to 27 grams times that by 9
Answer:
hydrochloric acid reacts with sodium hydroxide to form sodium chloride (the salt) and water.
Explanation:
Sodium chloride is made up of Na+ cations from the base (NaOH) and CI-anions from the acid (HCI).
Hope this helped!
Answer:
In diagram you have to show the electrons(dots) near to the more electronegative element by this you can show that this is an ionic bond.
Explanation:
