Rocks are grouped according to

1 answer:

8 0

<h2>Rocks are grouped according to their formation into three major groups – igneous, sedimentary, and metamorphic rocks </h2>

Explanation:

Based on their formation, rocks are further sub-grouped as:

Igneous - Intrusive or extrusive
Sedimentary – Clastic, chemical, or biologic rocks
Metamorphic - Foliated and non-foliated

Rocks are also grouped based on their properties like size, shape, texture, chemical composition, permeability, mineralogy, etc.

Based on properties rocks are sub-grouped as:

Igneous rocks – coarse or fine-grained; glassy or obsidian; felsic or mafic.
Sedimentary rocks - conglomerate, sandstone, breccia, shale, siltstone, chalk, crystalline or fossiliferous limestone, gypsum, rock salt etc.
Metamorphic rocks - Gneiss, hornfels, mylonites, cataclasties, marble, etc.

Consider the following chemical equilibrium: 4NH3+3O2=2N2+6H2O Now write an equation below that shows how to calculate from for

erma4kov [3.2K]

This is an incomplete question, here is a complete question.

Consider the following chemical equilibrium:

$4NH_3(g)+3O_2(g)\rightleftharpoons 2N_2(g)+6H_2O(g)$

Now write an equation below that shows how to calculate Kp from Kc for this reaction at an absolute temperature T. You can assume T is comfortably above room temperature. If you include any common physical constants in your equation be sure you use their standard symbols, found in the ALEKS Calculator.

Answer :

The expression of $K_c$ will be,

$K_c=\frac{[N_2]^2[H_2O]^6}{[NH_3]^4[O_2]^3}$

The expression of $K_p$ will be,

$K_p=K_c(RT)$

Explanation :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

The given equilibrium reaction is,

$4NH_3(g)+3O_2(g)\rightleftharpoons 2N_2(g)+6H_2O(g)$

The expression of $K_c$ will be,

$K_c=\frac{[N_2]^2[H_2O]^6}{[NH_3]^4[O_2]^3}$

The relation between $K_p$ and $K_c$ is:

$K_p=K_c(RT)^{\Delta n}$

Form the above reaction we conclude that:

$\Delta n=n_{product}-n_{reactant}$

$\Delta n=(6+2)-(4+3)$

$\Delta n=1$

The expression of $K_p$ will be,

$K_p=K_c(RT)^{1}$

$K_p=K_c(RT)$

What's a good idea for a limiting reactant project

amid [387]

Original Recipe
1 (18 1/4 ounce) Box devils food cake mix
1/2 cup vegetable oil
2 large eggs
Confectioners' Sugar (for rolling)

Directions:
Preheat oven to 350 degrees. Stir (by hand) cake mix, oil, and eggs- until dough forms. Dust with sugar and shape into 1 inch balls. Roll balls in sugar and place on ungreased cookie sheet. Bake 8-10 minutes. Remove from pan after one minute and put on cooling rack.
Cooking for 17 people
My original yield was 30 cookies.

17 cookies (1box cake mix/30 cookies)= .56 of a box= 1/2 box

17 cookies (1/2 cup oil/30 cookies)= .283 cups of oil= 1/4 cups

17 cookies (2 eggs/30 cookies)= 1.13 eggs= 1 egg
Percent Yeild
I was able to bake 24 cookies, with my original yeild being 30.

(24 cookies/30 cookies) x 100= 80% yeild
