It's harmful to humans; especially Children and Infants. Because it affects the development of the brain and nervous system
Answer:
The reaction that takes place in an electro-chemical cell is the Redox reaction, a type of reversible reaction combining both oxidation and reduction reactions.
To find the volume occupied by 2.0 g of CS₂ gas we can use the ideal gas law equation
PV = nRT
where P - pressure - 726 mmHg x 133 Pa/mmHg = 96 558 Pa
V - volume
n - number of moles = mass / molar mass
number of CS₂ moles = 2.0 g / 76.15 g/mol = 0.026 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature in kelvin - 70 °C + 273 = 343 K
substituting these values in the equation
96 558 Pa x V = 0.026 mol x 8.314 Jmol⁻¹K⁻¹ x 343 K
V = 0.768 L
the volume occupied is 0.768 L
C. 2
2H_2O + <u>2e</u>^(-) → H_2 + 2OH^(-)
2Cl^(-) → Cl_2 + <u>2e</u>^(-)
2H_2O +Cl^(-) + <u>2e</u>^(-) → H_2 + Cl_2 + 2OH^(-) + 2e^(-)
2H_2O +2Cl^(-) → H_2 + Cl_2 + 2OH^(-)
This is a <em>redox reaction</em> in which two chloride ions transfer two electrons to two molecules of water.
