Answer:
A
Explanation:
Chemical compound
Lead(II) chloride is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water. Lead(II) chloride is one of the most important lead-based reagents. It also occurs naturally in the form of the mineral cotunnite.
I think it might be a refracting telescope, but I do know it is between refracting telescope and reflecting telescope
Answer:
Fe + CuSO4 → Cu + Fe2(SO4)
2. Combine lead (II) nitrate and potassium iodide solutions.
Pb(NO3)2+ Kl → KNO3 + PbI2
3. Combine magnesium metal and hydrochloric acid solution.
Mg + HCl → MgCl 2(aq) + H 2(g)
4. Electrolysis (splitting) of water.
H2O → Im not sure sorry
5. Burning magnesium.
Mg + O2 → MgO
Explanation:
9)
balanced equation: CuSO₄ + Zn(s) ---> ZnSO₄ + Cu(s)
reaction type: single replacement
10)
balanced equation: H₂O₂ ----> H₂O + O₂ catalyst MnO2 under the arrow.
reaction type: decomposition
Oxygen and carbon because carbon dioxide is made of that
