Am i right?
8. I disagree since you have one reactant breaking into two products which is decomposition
9. I agree
10. I agree
Yes, you are correct.
The reaction in question 8, NaCl > Na + Cl2, is a synthesis reaction.
The reaction in question 9, KOH + HNO3 > HOH + KNO3, is a double replacement reaction.
The reaction in question 10, Ca + S > CaS, is also a synthesis reaction.
Yes, you are correct in your answers. Let me explain how to determine the types of reactions for each question:
8. The reaction equation given is NaCl > Na + Cl2. This is an example of a synthesis reaction, where two or more substances combine to form a new compound. In this case, sodium chloride (NaCl) is decomposing into sodium (Na) and chlorine gas (Cl2).
9. The reaction equation given is KOH + HNO3 > HOH + KNO3. This is an example of a double replacement reaction, where the positive ions of two compounds switch places. In this case, potassium hydroxide (KOH) and nitric acid (HNO3) react to form water (HOH) and potassium nitrate (KNO3).
10. The reaction equation given is Ca + S > CaS. This is an example of a synthesis reaction, where calcium (Ca) and sulfur (S) combine to form calcium sulfide (CaS).
Great job! Keep up the good work!
