Answer:
C. AgNO3 + LICI - AgCl + LINO3
Explanation:
Here the chemical equation for double displacement reaction is
AgNO3 + LICI - AgCl + LINO3
The reaction in which two compounds react together to form two other compounds by mutual exchange of their ions is called double displacement reaction.
Hope it will help :)
Answer:
Magnesium oxide
Explanation:
The substance which undergoes combustion is said to be combustible.It is called fuel. If a magnesium ribbon is heated,it starts burning. When a magnesium ribbon burns,it combines with the oxygen of air to form magnesium oxide,and liberates heat and light.

heptyne = 7
Answer:
39.2 g
Explanation:
- 2Ni₂O₃(s) ⟶ 4Ni(s) + 3O₂(g)
First we <u>convert 55.3 grams of Ni₂O₃ into moles of Ni₂O₃</u>, using its<em> molar mass</em>:
- 55.3 g ÷ 165.39 g/mol = 0.334 mol Ni₂O₃
Then we <u>convert 0.334 moles of Ni₂O₃ into moles of Ni</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:
- 0.334 mol Ni₂O₃ *
= 0.668 mol Ni
Finally we <u>calculate how much do 0.668 Ni moles weigh</u>, using the<em> molar mass of Ni </em>:
- 0.668 mol Ni * 58.69 g/mol = 39.2 g
last one? don't take my word though
