Answer:
B) 0.59 M NaCl.
Explanation:
- It is known that the no. of millimoles of NaCl before dilution = the no. of millimoles of NaCl after dilution.
∵ (MV) before dilution = (MV) after dilution.
<em>∴ M after dilution = (MV) before dilution / V after dilution </em>= (3.2 M)(25.0 mL)/(135.0 mL) = <em>0.5926 M ≅ 0.59 M.</em>
Answer:
If more solute is added and it does not dissolve, then the original solution was saturated
If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container must be saturate
Explanation:
Answer:
The average translational kinetic energy per atom for nitrogen atoms (not N₂) in a gas of nitrogen at atmospheric pressure at a temperature of 81 ∘C = 7.32 × 10⁻²¹ J
Explanation:
Average translational kinetic energy is given by
Eₐᵥ₉ = 3RT/2Nₐ
R = molar gas constant
T = absolute temperature in Kelvin
Nₐ = Avogadro's constant
The average translational kinetic energy is given more conveniently as
Eₐᵥ₉ = 3kT/2
k = Boltzmann's constant = (R/Nₐ) = 1.381 × 10⁻²³ J/K
T = 81 + 273.15 = 353.15 K
Eₐᵥ₉ = (3 × 1.381 × 10⁻²³ × 353.15)/2 = 7.32 × 10⁻²¹ J
No. Reactants: 1 silver, 1 chlorine; products: 4 silver, 4 chlorine. Therefore, not balanced.
Cellular Respiration is the process of breakdown of sugar molecules, especially glucose to yield energy in the form of ATP. Every organism undergoes cellular respiration.
<h3>What are the requirements of cellular respiration?</h3>
- Cellular respiration can take place in the presence of oxygen (aerobic) and in the absence of oxygen (anaerobic) to yield energy.
- In aerobic cellular respiration, the glucose is broken down in the presence of oxygen to yield energy, carbon dioxide, and water. The process is seen in many plants and animals.
Thus, cellular respiration is the process of the breakdown of glucose in the presence or absence of oxygen to yield energy.
