Explanation:
The grey powder of silver ( I ) oxide i.e. Ag₂O breaks down to give a metal called the silver metal and an odorless , colorless gas , which is the oxygen gas .
The balanced chemical reaction is as follows -
Silver oxide -----> Silver + oxygen
Ag₂O ------> Ag (s) + O₂ (g)
The balanced reaction is -
2 Ag₂O (s) ------> 4 Ag (s) + O₂ (g)
Answer:
Explanation:
Compared to the process of extracting lithium from mineral deposits, the process of extracting lithium from evaporation ponds requires __less____ water, __less____ money, and ___less________ time.
Lithium extraction from salar brines are more economical to extract compared to extraction from their natural ore deposits. Salar brines occurs as liquid underground brine reservoirs. Once pumped to the surface in ponds, they are left to evaporate and the lithium is concentrated from them. Extraction from brines in ponds do not require water that much, less cost and if the evaporation rate is fast, a lot of time can be saved.
Extraction from mineral deposits require a lot of energy and time to achieve.
Answer:
4.415 g of FeSO₄
Explanation:
The balance chemical equation for given single replacement reaction is as follow;
Fe + H₂SO₄ → FeSO₄ + H₂
Data Given;
Volume = 650 mL = 0.65 L
Density at STP = 0.08988 g/L
Mass = Density × Volume = 0.08988 g/L × 0.65 L = 0.0584 g
Step 1: <u>Calculate Moles of H₂ as; </u>
Moles = Mass / M.Mass
Moles = 0.0584 g / 2.01 g/mol
Moles = 0.0290 mol of H₂
Step 2: <u>Find out moles of FeSO₄ as;</u>
According to balance chemical equation,
1 mole of H₂ is produced along with = 1 mole of FeSO₄
So,
0.0290 moles of H₂ will be produced along with = X moles of FeSO₄
Solving for X,
X = 0.0290 × 1 mol / 1 mol
X = 0.0290 moles of FeSO₄
Step 3: <u>Calculate mass of FeSO₄ as;</u>
Mass = Moles × M.Mass
Mass = 0.0290 mol × 151.90 g/mol
Mass = 4.415 g of FeSO₄
