Explanation:
The equilibrium constant, Kc, for the reaction H2 (g) + 2 (g) 2H (g) is 54 at 425 ºC. If the equilibrium mixture contains 0.030 M H and 0.015 M 2 , the equilibrium concentration of H2 is______.
Answers
Answer:
[H₂] = 0.0011M
Explanation:
Based on the chemical equation:
H₂(g) + I₂(g) ⇄ 2HI(g)
And Kc is defined as:
Kc = [HI]² / [H₂] [I₂]
Where Kc = 54
And [] represents equilibrium concentration of each compund.
Replacing:
54 = [0.030M]² / [H₂] [0.015]
[H₂] = [0.030M]² / 54* [0.015]
[H₂] = 0.0011MIn the formation of silicon carbide represented by the chemical equation sio2+3c-->sic+2co 8.0 moles of each reactant are available for the reactant.What is the limiting factor?

What are 4 signs that chemical reaction had occurred?
Answers
Answer:
Color Change.
Production of an odor.
Change of Temperature.
Evolution of a gas (bubbles)
Precipitate (formation of a solid)
There are 5 so you can choose 4.
The four signs that a chemical reaction has occurred are as follows:
Change in color.Alteration in temperature.Change in the state along with precipitation.The evolution of gas in form of bubbles. What is a Chemical reaction?A chemical reaction may be defined as a process that significantly involves the chemical transformation of one set of chemical substances to another. This process involves the utilization of substances known as reactants that are transformed into other substances known as products.
Every chemical reaction involves the four signs which are mentioned above. These signs are delivered by chemical reactions along with determined products. But the mass of the reactants and products always remains the same. Precipitation is only visualized in specific reactions with the possessions of certain characteristics.
Therefore, the four signs that a chemical reaction has occurred are well-mentioned above.

Answers
Answer:
9 is clay, silt, sand in that order
Explanation:
Loam soil contains 10 to 20 percent clay, 40 percent silt and 40 percent sand. Less than 50% of the soil is made up of minerals; the remainder is made up of organic matter and void space.
What is Loam soil?Clay, sand, plus silt are the three minerals that make up loam soil. Loam is the best soil for growing plants when mixed in the appropriate amounts. Less than 50% of the soil is made up of minerals; the remainder is made up of organic matter and void space.
In loam soil, little will grow without the latter two. The ideal combination of clay, sand, plus silt will provide the void where minerals, organic materials, water, and air may support life. Loam soil contains 10 to 20 percent clay, 40 percent silt and 40 percent sand. Basalt transforms into clay-like soil, whereas granite decomposes into silty sands.
Therefore, loam soil contains 10 to 20 percent clay, 40 percent silt and 40 percent sand.

Answers
Answer: Hydrogen belongs to group 1 metal elements in the periodic table.
Explanation:
The hydrogen is a highly active metal. It has a single electron in its valence shell and it can donate its electron to other metal atoms. Thus forming metal hydrides. The hydrogen when ignited it reacts with oxygen and burns explosively this is indicative of high reactivity and spontaneous reactivity of hydrogen atom.

Explain where you would find the three different types of muscles (cardiac, smooth and skeletal) and how these different types of muscles are used in the body.
Answers
Explanation: Skeletal muscle, attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control. The basic unit is the muscle fiber with many nuclei. These muscle fibers are striated (having transverse streaks) and each acts independently of neighboring muscle fibers.

If 150 grams of oxygen are produced, how many moles of sodium chlorate decomposed
Answers
Answer:
3.13 moles of sodium chlorate are decomposed.
Explanation:
Given data:
Mass of oxygen produced = 150 g
Number of moles of sodium chlorate decomposed = ?
Solution:
Chemical equation:
2NaClO₃ → 2NaCl + 3O₂
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 150 g/ 32 g/mol
Number of moles = 4.7 mol
Now we will compare the moles of oxygen with sodium chlorate.
O₂ : NaClO₃
3 : 2
4.7 : 2/3×4.7 = 3.13 mol
3.13 moles of sodium chlorate are decomposed.
