Answer:
For the second to last problem the coefficients is 1, 5, 3, and 4 and the last problem all the coefficients are 1's
Explanation:
For the second to last problem you put 3 next to CO₂ so C is 3 on both sides. Then you put 4 next to H₂O because H will then be 8 on both sides. Lastly you put 5 next to O₂ which will make 10 on the reactant side. On the product side the 3 next to CO₂ will make O on the product side 6 and the 4 next to H₂O will make O on the product side 4. You will then add both together and it will make 10, which will make 10 on both sides. Hope this helps!
The property of ionic compounds is <u>Option B. they react with water and oxygen.</u>
Ionic compounds are very strong and require a lot of energy to break down so they have high boiling and melting points. Ions are formed due to electrostatic attraction between oppositely charged ions. All ionic compounds form crystals. Ionic compounds tend to have high melting and boiling points. Ionic compounds are very hard and very brittle.
Ionic compounds conduct electricity when dissolved in water. A property that is not characteristic of ionic compounds is that they are good conductors of electricity as solid crystals. Description To form a neutral ionic compound the cation and anion charges must be balanced. Some of the physical properties of ionic compounds are Physical State Ionic compounds are solid and relatively rigid due to the strong attraction between cations and anions.
