Answer:
The correct answer is the third statement, that is, when the heated substance gets near to the surface, it starts to cool.
Explanation:
A current that arises within a fluid due to convection is termed as the convection current. In comparison to the surface, the core is extremely hot, thus, both core and the surface exhibit very distinct temperatures. The mantle rises towards the surface when it gets heated as it moves close to the core. However, when it moves towards the surface, the mantle starts to turn cool and denser.
Afterward, the magma, which is cool, again then begins to move close to the core, and gets heated and rises again, this phenomenon results in the emergence of convection currents.
Answer:
Au3+(aq) + 3Cu+(aq) → Au(s) + 3Cu2+(aq)
1.35 V
Explanation:
Given that the reduction potential of
Cu^2+(aq) + e- -----> Cu^+(aq) is +0.15 V
While the reduction potential of
Au3+(aq) + 3 e- -----> Au(s) is + 1.50V
It is clear that the Cu^+(aq)/Cu^2+(aq) system is the anode while Au^3+(aq)/Au(s) system is the cathode based on the reduction potentials shown above. The number of electrons transferred (n) =3
E°cell = E°cathode - E°anode
E°cell= 1.50-0.15
E°cell= 1.35 V
Answer:C. Hydrogen Bonds with themselves and entropy decreases.
Explanation:Limonene is a chiral aliphatic Hydrocarbon liquid that is relatively stable as MONOTERPENE which cracks at high temperature to produce ISOPRENE. D-limonene is produced from CITRUS FRUIT through CENTRIFUGAL SEPARATION AND STEAM DISTILLATION. The most widely used conversion of limonene is to CARVONE.
The water molecules around LIMONENE forms Hydrogen Bonds with themselves and entropy of the reaction decreases,the name Limonene was obtained from the PEEL OF LEMON.
Answer:
The energy should be high.
Explanation:
Bonds do store energy and release it depending if it's endothermic or exothermic. The energy should be low because when a bond forms (endothermic) it releases heat, which helps form bonds. Having a high energy means the bond is absorbing energy, which helps break bonds (endothermic). How this helps!
Polar liquids have both negative and positive ends.
