<span>BaCl2 + Na2SO4 --> BaSO4 + 2NaCl
In this reaction, 1.0 g of BaCl2 and 1.0 g of Na2SO4 are present. We need to identify the limiting reactant.
"First, convert grams to moles"
1.0 g BaCl2 * (1 mol BaCl2 / 208.2 g BaCl2) = 4.8 x 10^-3 mol BaCl2
1.0 g Na2SO4 * (1 mol Na2SO4 / 142.04 g Na2SO4) = 7.0 x 10^-3 mol Na2SO4
(7.0 x 10^-3 mol Na2SO4 / 4.8 x 10^-3 mol BaCl2) = 1.5 mol Na2SO4 per mol BaCl2
"Using this ratio to compare with the balanced equation, BaCl2 + Na2SO4 --> BaSO4 + 2NaCl"
The balanced equation indicates that 1 mol of BaCl2 reacts with 1 mol of Na2SO4. However, we found that 1.5 mol of Na2SO4 is available for each mol of BaCl2. Therefore, BaCl2 is the limiting reagent.</span>
Answer:

Explanation:
Charge of one electron = 
The formula for calculating charge is:

Given that: Charge = 


Total electrons, n = 
Response:
Hydropower generates energy at a quicker rate because water is perpetually recycled in the hydrogeological cycle.
Clarification:
Hydropower primarily derives from water that cycles through the hydrogeological framework. This resource is replenished quickly within the climate system sporadically. We can predict and estimate an area's capacity for hydroelectricity generation effectively. Water is indeed a renewable resource.
In contrast, nuclear energy sources are geological. Not all substances exhibit radioactivity. Specific conditions must exist for an isotope to display spontaneous radioactivity. Minerals containing useful radioactive materials, which serve as fuel in nuclear plants, are mined. Geological processes evolve over extended periods, leading to the classification of nuclear energy sources as non-renewable resources.
