Campers want a travel cup that keeps the temperature of a beverage from changing for up to two hours.
They may want to keep a hot drink hot when they are in a cold place. Or they may want to keep a cold drink
from warming up in a hot environment,
Describe how you plan to design, build, and test a travel cup that uses thermal insulators?
The statement is "thermal insulators of a double-layered vacuum seal make a liquid heated when it's cold and keep it cool when it's hot."
What is thermal insulator?A thermal insulator is a material that inhibits heat from being conveyed from one location to another.
Campers seek a travel cup that cools liquids with a cold pack. Design the exterior portion of the cup to keep the drink cold after it has cooled down, as well as the interior compartment to contain the cold pack and channel heat from the liquid in the cup. One of the greatest ways to keep your coffee hot for a long time is to use vacuum insulation in a thermos. On the surface, the concept appears straightforward.

Explanation:
Calculate the molarity of a solution prepared by dissolving 6.87 grams of AgNO3 in enough water to make 2.50 liters of solution.
Answer:
The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]
Explanation:
Molar concentration is a measure of the concentration of a solute in a solution.
Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.
Molarity is determined by dividing the moles of the solute by the volume of the solution:
[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
Being 169.87 g / mole the molar mass of AgNO₃, then you can apply the following rule of three: if 169.87 grams are contained in 1 mole, 6.87 grams are contained in how many moles?
[tex]amount of moles=\frac{6.87 grams*1 mole}{169.87 grams}[/tex]
amount of moles= 0.04 moles
Then:
number of moles of solute: 0.04 molesvolume: 2.50 LReplacing:
[tex]Molarity=\frac{0.04 moles}{2.50 L}[/tex]
Solving:
Molarity= 0.016 [tex]\frac{moles}{L}[/tex]
The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]

Explanation:
Organisms change energy from the environment or from their food into other types of energy. This is called what?
Answer:
Metabolism
Explanation:
This is called Metabolism.
Metabolism is a combination of spontaneous chemical reactions which release non-spontaneous energy and chemical reactions requiring energy to proceed. In order to perform cellular processes, living organisms can take energy from food, nutrients or sunlight.

The gas phase decomposition of phosphine at 120 °C
PH3(g)1/4 P4(g) + 3/2 H2(g)
is first order in PH3 with a rate constant of 1.80×10-2 s-1.
If the initial concentration of PH3 is 8.48×10-2 M, the concentration of PH3 will be 2.45×10-2 M after
s have passed.
Answer:
The decreasing in concentration occurs after 69.0s
Explanation:
A first order reaction follows the equation:
Ln [A] = -kt + ln[A]₀
Where [A] is the concentration of the reactant after time t
k is rate constant of the reaction
And [A]₀ is the initial concentration of the reactant
Replacing:
Ln 2.45x10⁻²M = -1.80x10⁻²s⁻¹*t + ln8.48x10⁻²
-3.709 = -1.80x10⁻²s⁻¹*t -2.467
-1.2416 = -1.80x10⁻²s⁻¹*t
69.0s = t
The decreasing in concentration occurs after 69.0s

PLEASE Answer asap! Compare two periodic families below. You must include at least two facts about each family. You may use any description of properties or periodic trends to help you.
Answer:
The alkali metals/group 1 are recognized as a group and family of elements. These elements are metals. Sodium and potassium are examples of elements in this family. Hydrogen is not considered an alkali metal because the gas does not exhibit the typical properties of the group. The largest family of elements consists of transition metals/group 3-12/group 3a. The center of the periodic table contains the transition metals, plus the two rows below the body of the table (lanthanides and actinides) are special transition metals. Even though both are metals, transition metals have higher melting points; they have higher density; they are less reactive with water; they react and form ions with different charges, but Group 1 metals only form 1+ ions.
