Answer:
D.
Explanation:
D is the correct answer because, in aqueous solution, solvent is water and solute (in this example carbon dioxide CO₂) is a substance dissolved in water. The amount of solute that can be dissolved in a solvent depends of chemical composition, temperature and pressure
Fuel cells work by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. On the anode site, hydrogen molecules are split into electrons and protons. They have a high efficiency therefore these fuel cells are also considered to be very clean plus a fuel cells only by-products are electricity, excess heat, and water.
1)sodium chloride/common salt
2)sodium hydroxide
3)sodium carbonate/washing soda
4)sodium bi-carbonate/baking soda
5)calcium hypochlorite/bleaching power
6)hemihydrate calcium sulphate/plaster of Paris
7)calcium sulfate
8)copper sulfate
9)bororn trifluoride
10)potassium nitrate
I could only find ten examples
The answer is: the rate of reaction is 850 g/min.
n(P₄O₁₀) = 1.5 mol; amount of product.
M(P₄O₁₀) = 283.9 g/mol; molar mass of phosphorus(V) oxide.
m(P₄O₁₀) = n(P₄O₁₀) · M(P₄O₁₀).
m(P₄O₁₀) = 1.5 mol · 283.9 g/mol.
m(P₄O₁₀) = 425.85 g in 30 seconds.
Make proportion: 425 g : 30 s = m(P₄O₁₀) : 60 s.
m(P₄O₁₀) = 850 g in 60 s.
I think the correct answer from the choices listed above is option A. It is the salt bridge that balances charges that may build up as reduction and oxidation occur in a voltaic cell. The salt bridge is to <span>maintain charge balance because the electrons are moving from one half cell to the other.</span>
