long toes
Explanation:
the other traits are personality related, not a biological factor. they can be learned, but not inherited
The answer is b
Explanation:
<span>During cooling, the kinetic energy of the molecules falls, be</span>cause, when cooling a substace, the particles (molecules) slow down.
The kinetic energy is related to the speed, such that the lower speed the lower kinetic energy.
Particles can translate and vibrate, in the case of gases and liquids, and only vibrate (in the case of solids).
As a substance is cooled the particles get closer and the motion (translation and vibration), slows down. You can see by the equation of the kinetic energy (KE):
KE = [1/2]mass×(speed)² that as the speed is lower the KE will also be lower.
Additionally, when the cooling does not drive a change of phase (gas to liquid, liquid to solid, or solid to gas), it drives a decrease on temperature. In this case you should know that the temperature is a measure of the kinetic energy: the lower the temperature, the lower the kinetic energy.
Answer:
arsenic
Explanation:
nitrogen=155pm
phosphorus=195pm
arsenic =between 38 μm and 25 mm
The added KI does not have any impact
The reaction invovles Titration of vitaminc ( Ascorbic acid)
ascorbic acid + I₂ → 2 I⁻ + dehydroascorbic acid
the excess iodine is free reacts with the starch indicator, forming the blue-black starch-iodine complex.
This is the endpoint of the titration. since alreay excess KI is added ( the source of Iodine), it does not have an influence.
Answer B
Hope this helps!
