Answer: A. It reflects sunlight
hope this helps let me know if it's wrong
Answer:
d.3.0
Explanation:
Step 1: Calculate the final volume of the solution
The final volume is equal to the sum of the volumes of the initial HCl solution and the volume of distilled water.
V₂ = 100 mL + 100 mL = 200 mL
Step 2: Calculate the final concentration of HCl
We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁/V₂ = 0.002 M × 100 mL/200 mL = 0.001 M
Step 3: Calculate the pH of the final HCl solution
Since HCl is a strong acid, [H⁺] = HCl. We will use the definition of pH.
pH = -log [H⁺] = -log 0.001 = 3
The choices can be found elsewhere and as follows:
A.) a definite shape and a definite volume
B.) a definite shape but no definite volume
C.) no definite shape and no definite volume
I believe the correct answer is option C. Two basic properties of the gas phase would be it has no definite shape and no definite volume. It takes the shape and volume of its container. Hope this answers the question.
Energy transfer is an extension of Newton’s Laws. Energy cannot be created nor destroyed; it can only be transferred. The moving body has energy, called kinetic energy, and this energy will be transferred into something else as the body slows. Likewise, the car crashing into you will transfer its kinetic energy to you. The other type of energy is potential energy, or stored energy. Think of a spring. When you pull it, you are storing energy. When you let it go, this potential energy is transferred into kinetic energy as motion. Car manufacturers engineer a purposeful flaw into the structure, the Crumble Zone. This Crumble Zone is a structurally assigned place for kinetic energy to be transferred into potential energy in the case of an accident. When two cars collide, the kinetic energy is used up to fold the metal of the auto, keeping the destructive energy out of the passengers. The same science is behind the recommendation that motorcyclists wear helmets and body armor. Auto crumble zones, as well as air bags, helmet foam and Kevlar, are all methods for converting harmful kinetic energy into safe potential energy.
