1.5 = 1500g/Volume
Rearrange the equation:
Volume = 1500/1.5 = 1000
So your answer is 3. 1000 cm3
Given the mass (in grams) of a reactant A, first divide this by the molar mass of A to get the number of moles of A. Then balance the chemical reaction, and divide the number of moles of A by the coefficient of A in the balanced reaction. Next, find the coefficient of the product (B) in the reaction, and multiply this by the result from the previous operation. Finally, multiply by the molar mass of B to get the final answer in grams of the product B.
Answer:
Na2O
explanation.
Ionic bonds refers to complete transfer of electrons from one atom to another
Atomic mass cadmium = 112.41 amu
1 mole Cd ------------ 112.41 g
?? moles Cd --------- 18.2 g
18.2 x 1 / 112.41 => 0.161 moles of Cd
hope this helps!
Reaction on positive electrode (cathode):
PbSO₄₍s₎ + 2H₂O₍l₎ → 2e⁻ + PbO₂₍s₎ + 4H⁺₍aq₎ + SO₄²⁻₍aq₎.
s - solid.
l - liquid.
aq - dissolve in water.
PbSO4 is converted to Pb at one electrode (anode) and to PbO₂ at the other (cathode). Lead battery can be recharged, during recharging, an external source of energy is used.
