Answer:
A
Explanation:
temperature increase because burning causes heat therefore the planet heats up from all the fossil fuels burned aka "global warming"
The reduction reaction is the gain of electrons while oxidation reaction is the loss of electrons. For potassium ion(K+), the reaction should be K+ + e- ==> K. So the answer is (1).
Answer:
The filter that water went through faster is Filter paper
Data Given; T = 306 K
M.mass of CO = 28 g/mol = 0.028 Kg/mol
M.mass of CO₂ = 44 g/mol = 0.044 Kg/mol
M.mass of SO₃ = 80 g/mol = 0.080 Kg/mol
Gas Constant = R = 8.314 J/mol.K
Formula used; Vrms =
Putting values for CO; Vrms =
Vrms = 477 m.s⁻¹
Putting values for CO₂; Vrms =
Vrms = 380 m.s⁻¹
Putting values for SO₃; Vrms =
Vrms = 282 m.s⁻¹
Kinetic Energy;
K.E = 1/2 mv²
Putting values,
For CO,
K.E = 1/2 (0.028 Kg/mol) (477 m/s)²
K.E = 1/2 (0.028 Kg) (227529 m²/s²)
K.E = 3185 Kg.m².s⁻²For CO₂
,
K.E = 1/2 (0.044 Kg/mol) (380 m/s)²
K.E = 1/2 (0.044Kg) (144400 m²/s²)
K.E = 3176 Kg.m².s⁻²For SO₃
,
K.E = 1/2 (0.080 Kg/mol) (282 m/s)²
K.E = 1/2 (0.080 Kg) (79524 m²/s²)
K.E = 3180 Kg.m².s⁻²
