The correct answer is <span>Antoine-Laurent de Lavoisier. Hope this helps!</span>
energy can't be created or destroyed, but mass particles can decay or tranform into others as long as the total mass/energy (remeber E=MC2) is conserved, in nuclear reactions one type of sub-atomic particle change into another, this destabilizes the nucleus forcing it to split and release a certain amount of energy in the form of massless particles
Answer:
Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.Apr 4, 2017
Explanation:
Answer:
Ecel =0,04 V
Explanation:
Apply the Nerst equation,
Ecel= Ecelº - (RT/nF)*lnQ
where R=8,314 J/molK, T=25ºC=298K and F =96 485 Coulombs/mol e- and n=number of moles of electrons transferred in the balanced equation. Q is cocient of products and reactives power to respective coefficients, if is a gas apply partial pressure
Write the semiequation redox and verify the numbers of electron for balance. In this case you don't need to change nothing
2Cl−(aq)→Cl2(g) + 2e-
<u>2CO3+(aq) + 2e-→2CO2+(aq)</u>
2Cl−(aq) + <u>2CO3+(aq) </u>→<u>2CO2+(aq) + </u>Cl2(g)
Hence
Ecel= 0.483 V - 0.013Ln ([CO2+]^2*PCl2] / [CO3+]^2*[Cl-]^2)
Ecel= 0.483 V - 0.013Ln ([0.205]^2 * 7.3] / [0.19]^2*[0.144]^2)
Ecel =0,04 V
