The magnesium dissolves to form magnesium chloride and hydrogen gas is released.
Mg + 2HCl -----> MgCl2 + H2(g).
Answer:
0.5133805136 moles.
Explanation:
1 gram of Al2(Co3)3 equals 0.0017112683785004 moles, we need the amount of moles produced in 300 grams of Al2(CO3)3, so we have to multiply 1 gram of Al2(CO3)3 times 300: 0.0017112683785004 x 300, in conclusion,
300 grams of Al2(Co3)3 equals 0.5133805136.
There are 41.1984 grams of silver in 2.3x 10^23 atoms of silver
Answer:
12 L of O₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
CS₂ + 3O₂ —> CO₂ + 2SO₂
From the balanced equation above,
3 L of O₂ reacted to produce 1 L of CO₂.
Finally, we shall determine the volume of O₂ required to produce 4 L of CO₂. This can be obtained as follow:
From the balanced equation above,
3 L of O₂ reacted to produce 1 L of CO₂.
Therefore, xL of O₂ will react to produce 4 L of CO₂ i.e
xL of O₂ = 3 × 4
xL of O₂ = 12 L
Thus, 12 L of O₂ is needed for the reaction.
