Describe how you plan to design, build, and test a travel cup that uses thermal insulators?

Answers

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.

Calculate the molarity of a solution prepared by dissolving 6.87 grams of AgNO3 in enough water to make 2.50 liters of solution.

Answers

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 L

Replacing:

[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]

 why don't we ever see solid or liquid oxygen on earth?

Answers

Please mark me brainiest!

The reason why you don’t see solid or liquid oxygen is because oxygen is a natural occurring gas. Gas can not be solid or liquid because there is too much energy to have volume/shape. That’s why you see oxygen tanks, as the tank keeps the gas contained and that is why you can’t see it in the air outside or in something like H20 (water).

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.

Answers

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

Answers

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.
