Answer:
256 K
Explanation:
Given data
- Ideal gas constant (R): 0.0821 atm.L/mol.K
We can determine the temperature of the gas using the ideal gas equation.
P × V = n × R × T
T = P × V / n × R
T = 4.20 atm × 20.0 L / 4.00 mol × 0.0821 atm.L/mol.K
T = 256 K
The type of charge an electron carries is B negative
The correct answer is (D)
All the above are reasons the carbon , oxygen, and nitrogen cycles are vital to life on earth.
The explanation:
because :
1) Carbon, oxygen, and nitrogen are vital components of life on Earth.
2) The carbon, oxygen, and nitrogen cycles allow vital elements to return to usable form by organisms.
3)The carbon, oxygen, and nitrogen cycles are an important interface between biotic and abiotic factors
4) They are all biogeochemical cycles.
5) They all involve an interaction between living and nonliving elements.
6)They are all part of the Earth system.
Answer:
6 moles of electrons are transfered
Explanation:
The actual redox is
S4+ +6e- long arrow S2- + 3O2
From the reaction, addition of 6 electrons on the LHS is needed to balance the electron number, hence 6 moles of electrons are transfered
