The temperature is the same, so the amount of kinetic energy will also be the same.
Answer:
All soil is made up of inorganic mineral particles, organic matter (including living things), air and water. Inorganic mineral particles make up more than half the volume of soil. These particles come from rocks – the parent material that formed the soil.
Hope this helps!
Answer:
C = 0.5621J/g°C
Explanation:
Heat lost by metal = Heat gained by water
Heat gained by water;
H = MC ΔT
ΔT = 28 -25 = 3.0°C
M = 130.0g
C = 4.18 J/g°C
H = 130 * 4.18 * 3 = 1639J
Heat lost my metal;
H = MCΔT
ΔT = 100 - 28 = 72°C
M = 40.5g
C = ?
C = H / MΔT
C = 1639 / (40.5 * 72)
C = 0.5621J/g°C
Answer:
Substrate D
Explanation:
In substitution reactions the tertiary substrates cannot undergo substitution via neighboring group participation (NGP) due to the steric impediment, this means that the volume occupied by the substituents is very large and makes it impossible to attack the nucleophile to the substrate carbon.
Answer:
The atomic mass of lead is: 207.216 u
Explanation:
data Isotopes mass percent
1 203.97302 1.4
2 205.974444 24.1
3 206.97587 22.1
4 207.97663 52.4
atomic mass = (203.97302x 0.014) + (205.974444 x 0.241) +
(206.97587 x 0.221) + (207.97663 x 0.524)
atomic mass = 2.856 +49.639 + 45.742 + 108.979
atomic mass = 207.216 u
