When applying heat to (Aluminum hydroxide) it will decompose producing an aluminum compound.
Write the formula of this compound.________
Correct Answer
Al2O3
Explanation
When heat is applied to Aluminum hydroxide (Al(OH)3), it undergoes decomposition and produces aluminum oxide (Al2O3). This is because the heat causes the water molecules in the compound to evaporate, leaving behind the aluminum and oxygen atoms to combine and form aluminum oxide. Therefore, the formula of the compound produced is Al2O3.
45.
When reacting Nitric acid with Ca a compound and a gas produce.
Write the formula of the compound produced.________
Correct Answer
Ca(NO3)2
Explanation
When nitric acid (HNO3) reacts with calcium (Ca), it forms calcium nitrate (Ca(NO3)2) as the compound produced. This is because nitric acid is a strong acid that can donate hydrogen ions (H+) while calcium is a metal that can accept these ions. The resulting compound, calcium nitrate, is formed by the combination of one calcium ion (Ca2+) and two nitrate ions (NO3-) from the nitric acid.
46.
When reacting Magnesium Carbonate with HCl a compound, water and a gas produce.
Write the formula of the compound produced.________
Correct Answer
MgCl2
Explanation
When Magnesium Carbonate reacts with HCl, it undergoes a double displacement reaction. The Carbonate ion (CO3^2-) from Magnesium Carbonate combines with the Hydrogen ion (H+) from HCl to form water (H2O). The remaining Magnesium ion (Mg^2+) combines with the Chloride ion (Cl-) from HCl to form Magnesium Chloride (MgCl2). Therefore, the formula of the compound produced is MgCl2.
47.
When reacting Zinc with Steam a compound and a gas produce.
Write the formula of the compound produced.________
Correct Answer
ZnO
Explanation
When zinc reacts with steam, it forms zinc oxide (ZnO).
48.
When reacting Mg with Cold Water a compound and a gas produce.
Write the formula of the compound produced.________
Correct Answer
Mg(OH)2
Explanation
When magnesium reacts with cold water, it forms magnesium hydroxide (Mg(OH)2) as the compound produced. This is because magnesium reacts with water to produce magnesium hydroxide, which is a compound consisting of one magnesium ion (Mg2+) and two hydroxide ions (OH-).
49.
When reacting Ammonium Nitrate with Ca(OH)2 a compound, water and a gas produce.
Write the formula of the compound produced.________
Correct Answer
Ca(NO3)2
Explanation
When ammonium nitrate (NH4NO3) reacts with calcium hydroxide (Ca(OH)2), the products formed are calcium nitrate (Ca(NO3)2), water (H2O), and ammonia gas (NH3). Therefore, the formula of the compound produced is Ca(NO3)2.
