Answer:
In a classroom, the comparison that a teacher would most likely use for describing a mole is: jar of jellybeans and a gram of salt crystals.
Explanation:
We are asked to solve the temperature do Potassium Nitrate KNO3 and Sodium Chloride NaCl has the same molar solubility. The answer is 44.5 degrees Celsius. As per the definition of solubility temperature, the solubility increases when the temperature increases where molecules are allowed to move faster at a higher temperature.
ΔS = 0.250 J·K^(-1)
<em>Step 1</em>. Calculate the <em>moles of CO</em>
From the<em> </em><em>Ideal Gas Law</em>,
<em>n</em> = (<em>pV</em>)/(<em>RT</em>) = (8.00 kPa × 3.00 L)/(8.314 kPa·L·K^(-1)·mol^(-1) × 298.15 K)
= <em>0.009 682 mo</em>l
Δ<em>S</em> = <em>nC</em>_Vln(<em>T</em>_2/<em>T</em>1)
= 0.0096 82 mol × 20.17 J·K^(-1)mol^(-1) ln(1073.15 K/298.15 K)
= 0.1953 J·K^(-1) × ln3.599 = 0.250 J·K^(-1)
Answer: The Note
Explanation: Neurotransmitters are endogenous chemical substances that transmits signals through a NEUROMUSCULAR JUNCTIONS.
The signals are transmit from one NERVE CELL TO THE TARGET POINT such as Muscle cell,gland cell etc. Neurotransmissiom require the presence of synapse(the structure or medium through which neurosignals which can be an electrical or chemical signals to pass through).
Answer:
C. minerals within geodes are always framework silicates
Explanation:
This is true going by the facts that, it is only the silicates that can be able to form crystals as obtainable in diamonds etc. Since the minerals in geodes are in the framework of silicates families, they can be able to form euhedral crystals.
