If you have 1.5 grams of silver nitrate, how many grams of silver could
you produce?
Answer:
0.95g of Ag we can produce
Explanation:
To solve this question we have to convert the mass of silver nitrate (AgNO₃) to moles. The moles of silver nitrate = Moles of Ag. Then, with molar mass of Ag we can know the mass of silver:
Moles AgNO₃ -Molar mass: 169.87g/mol-:
1.5g * (1mol / 169.87g) = 0.0088 moles Ag
Mass Ag -Molar mass: 107.87g/mol-:
0.0088 moles Ag * (107.87g / mol) =
0.95g of Ag we can produce why don't we ever see solid or liquid oxygen on earth?
What is the Great Red Spot on Jupiter?
Answer:
The Great Red Spot is a storm in Jupiter's southern hemisphere with crimson-colored clouds that spin counterclockwise at wind speeds that exceed those in any storm on Earth. The Great Red Spot has slowly changed over the years, and is currently about 1.3 times as wide as our planet.
Calculate the value of Key in the following reaction if the equilibrium concentrations are
[H2S] -0.25 M, (H2) - 0.88 M, [S2] -0.44M.
2 H2Sig) = 2 H2(g) + S218)
Answer:
The value of the equilibrium constant Kc is 5.45
Explanation:
The "Law of Mass Action" states:
"For a reversible reaction in chemical equilibrium at a given temperature, it is true that the product of the concentrations of the products raised to the stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients is a constant."
This constant was called the equilibrium constant. For a reaction:
aA + bB ⇄ cC + dD
the equilibrium constant Kc is:
[tex]Kc=\frac{[C]^{c} *[D]^{d} }{[A]^{a} *[B]^{b} }[/tex]
In this case, the balanced reaction is:
2 H₂S → 2 H₂ + S₂
So, the equilibrium constant Kc is:
[tex]Kc=\frac{[H_{2} ]^{2} *[S_{2} ] }{[H_{2} S]^{2} }[/tex]
The equilibrium concentrations are
[H₂S] =0.25 M[H₂]= 0.88 M[S₂]= 0.44MReplacing in the definition of equilibrium constant:
[tex]Kc=\frac{(0.88 M)^{2} *0.44 M }{(0.25 M)^{2} }[/tex]
Solving:
Kc= 5.45
The value of the equilibrium constant Kc is 5.45
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.

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.

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

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.
