Option A
Explanation:
They are portable resources that convert chemical energy to electrical energy
Answer:
179.2g of O2
Explanation:
Fir, we must obtain a balanced equation for the reaction.
The equation for the reaction is:
2H2 + 02 —> 2H2O
Next, we find the molar mass of H2 and O2 as shown below:
Molar Mass of H2 = 2x1 = 2g/mol
Mass conc. of H2 from the balanced equation = 2 x 2 = 4g
Molar Mass of O2 =16x2 = 32g/mol
From the equation,
4g of H2 required 32g of O2,
Therefore 22.4g of H2 will require = (22.4x32)/4 = 179.2g of O2
62.3018 g/mol is the molar mass
Will refreact through the lens and diverge, never intersecting
Answer:
When ionic compounds are formed, energy is released which is exothermic energy. If the energy released during bond formation is reabsorbed, the ionic bond holding the positive ions and negative ions together will break apart which is endothermic energy.
