Answer:
Explanation:
Hello!
In this case, since the applied current for the 50.0 mins provides the following charge to the system:
As 1 mole of electrons carries a charge of 1 faraday, or 96,485 coulombs, we can compute the moles of electrons involved during the reduction:
Then the reduction of Ga³⁺ to Ga involves the transference of three electrons, we are able to compute the moles and therefore the mass of deposited gallium:
Best regards!
Answer:
1.83 atm
Explanation:
Total pressure is the sum of partial pressures, so the pressure of hydrogen and pressure of oxygen add to equal 4.53 atm
4.53 = 2.7 + Po
Po = 4.53 - 2.7 = 1.83 atm
Answer:
CO₂ + 4 H₂S + O₂ ---> CH₂O + 4 S + 3 H₂O
Explanation:
The unbalanced equation looks like this:
CO₂ + H₂S + O₂ ---> CH₂O + S + H₂O
Below is the amount of each element on each side of the reaction.
Reactants:
> 1 carbon, 2 hydrogens, 1 sulfur, 4 oxygens
Products:
> 1 carbon, 4 hydrogens, 1 sulfur, 2 oxygens
As you can see, there is a differing amount of hydrogens and oxygens on both sides. The balanced equation looks like this:
1 CO₂ + 4 H₂S + 1 O₂ ---> 1 CH₂O + 4 S + 3 H₂O
Below is the amount of each element on each side of the reaction.
Reactants:
> 1 carbon, 8 hydrogens, 4 sulfurs, 4 oxygens
Products:
> 1 carbon, 8 hydrogens, 4 sulfurs, 4 oxygens
debris from the volcanic ash has covered the sun which makes the temperature cold.
The answer is A for sure hit thanks !
