I'm pretty sure the answer would be that the metal is conductive, which travels through the copper wires.
Answer:
Nitrogen is an inert gas — meaning it doesn't chemically react with other gases — and it isn't toxic. But breathing pure nitrogen is deadly. That's because the gas displaces oxygen in the lungs. Unconsciousness can occur within one or two breaths, according to the U.S. Chemical Safety and Hazard Investigation Board.
Answer:
1.38*10^4 L or 0.138*10^2 m^3
Explanation:
The balanced equation for the reaction is:
⇒
In the chemical equation above, 3 moles of hydrogen gas react with 1 mole of nitrogen gas to produce 2 moles of ammonia gas. A STP, 1 mole of gas is equivalent to 22.4 L. Therefore,
6.9 m^3 of nitrogen gas will be equivalent to 6900 L. In addition, 6900L will be equivalent to 6900/22.4 = 308.036 moles
1 mole of nitrogen produced 2 moles of ammonia gas, therefore, 308.04 moles of nitrogen gas would produce 2*308.036 moles = 616.07 moles of ammonia gas
At STP, 1 mole of gas is equivalent to 22.4 L, thus 616.07 moles will be equivalent to 22.4*616.07 = 13800 L or 13.8 m^3
Answer:
1.175 M
Explanation:
Mass = 32.9 g
Volume = 700.0 mL = 0.7 L
Molarity = ?
The relationship between the quantities is given by;
Molarity = Number of moles / Volume
Number pf moles = Mass /Molar mass
Number of moles = 32.9 / 40 = 0.8225 mol
Molarity = 0.8225 / 0.7 = 1.175 M
The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized
