Answer:
0.113 M
Explanation:
Since B and D are on opposite sides of the reaction, the concentration of D increases when the concentration of B decreases. The amount by which D increases is determined by the coefficients of B and D in the balanced chemical equation:
[D]=(0.045 M)=0.113 M.
Answer:
<u>2.13</u> moles of AlCl3 are produced from 3.2 moles of Cl2
Explanation:
Moles : The amount of substance that contain as many particles as present in 12 grams of C-12.
The balanced equation for the reaction is :
This reaction shows the following :
2 mole Al = 3 mole Cl2 = 2 mole AlCl3
In question we are asked to calculate the moles of AlCl3 produced from Cl2
So, we will use only Cl2 andAlCl3 moles
3 mole Cl2 = 2 mole AlCl3
1 moles of Cl2 will give =
of AlCl3
3.2 moles of Cl2 will give =
of AlCl3
= 2.133 moles
Answer:
3.8 cm
Explanation:
Given data
Volume of a sphere: V = 4/3 × π × r³ = 4/3 × π × (2.5 cm)³ = 65 cm³
We can find the final volume using the combined gas law.
The final radius of the bubble is:
V = 4/3 × π × r³
223 cm³ = 4/3 × π × r³
r = 3.8 cm
