76. The level of muddy water will decrease slightly if the model is left in a sunny location for several days because of Evaporation. The sun will vaporize the water found in the mud, turning it into it's gaseous state, which will then cause it to rise up and get stuck on the plastic wrap.
77. Precipitation
78.The reason that the sediment in the muddy water will remain the same is because the Mud will never evaporate like the water will, and therefore it will remain at the bottom of the container.
Hope that helps!
Answer:
Answer: The increase in force will directly effect the pressure exerted by the gas that is high pressure of the gas.
Explanation:
Answer:
12.6.
Explanation:
- We should calculate the no. of millimoles of KOH and HCl:
no. of millimoles of KOH = (MV)KOH = (0.183 M)(45.0 mL) = 8.235 mmol.
no. of millimoles of HCl = (MV)HCl = (0.145 M)(35.0 mL) = 5.075 mmol.
- It is clear that the no. of millimoles of KOH is higher than that of HCl:
So,
[OH⁻] = [(no. of millimoles of KOH) - (no. of millimoles of HCl)] / (V total) = (8.235 mmol - 5.075 mmol) / (80.0 mL) = 0.395 M.
∵ pOH = -log[OH⁻]
∴ pOH = -log(0.395 M) = 1.4.
∵ pH + pOH = 14.
∴ pH = 14 - pOH = 14 - 1.4 = 12.6.
Answer:
the answer is A.
Explanation:
Elemental fluorine, for example, is the strongest common oxidizing agent.
Answer: Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.
