the prefix of the second word indicates that a molecule of carbon dioxide indicates that the compound contains two oxygen atoms
Explanation:
Simple cell has liquid chemicals and it is difficult to carry from one place to another. Dry cell has no solution. So, it is easier to carry it from one place to another and there is no risk of spilling acid from the dry cell.
Answer:
51.17g of Cl2O7
Explanation:
The equation for the reaction is given below:
Cl2O7 + H2O → 2HClO4
First, let us calculate the masses of Cl2O7 and HClO4 from the balanced equation. This is illustrated below:
Molar Mass of Cl2O7 = (2x35.5) + (16x7) = 71 + 112 = 183g/mol
Molar Mass of HClO4 = 1 + 35.5 + (16x4) = 1 + 35.5 + 64 = 100.5g/mol
Mass of HClO4 from the balanced equation = 2 x 100.5 = 201g
Now, we can obtain the mass of Cl2O7 that must react to form 56.2g HClO4. This is illustrated below:
From the equation above,
183g of Cl2O7 reacted to produced 201g of HClO4.
Therefore, Xg of Cl2O7 will react to produce 56.2g of HClO4 i.e
Xg of Cl2O7 = (183 x 56.2)/201
Xg of Cl2O7 = 51.17g
From the calculations made above, 51.17g of Cl2O7 is required to produce 56.2g of HClO4
