in equilibrium?
2H2 +022H₂0

C. All of the molecules would react more slowly.
D. H₂O would react to produce H₂ and O₂ more quickly.

Answer:

Volume = 72.7272

Explanation:

if only pressure and volume change, then we can do some simple math to find the answer.

2 x 10 ^ 6 times 1 x 10 ^-5 = 20

pressure and volume must equal 20

20 = 0.275 x volume

20 / 0.275 = new volume

I don't remember significant digits but your volume is 72.72727272 just repeated

If we have a 1.0 x 10 -5 liter sample of a gas at that pressure, then release the pressure until it is equal to 0.275 atm, the new volume will be 72.7272

Volume is the space occupied by a three-dimensional object.

By the Boyle's law

[tex]\rm P_1V_2= P_1V_2[/tex]

P1 (initial pressure) = [tex]2.0 \times10^6 atm[/tex]

V1 (initial volume) = [tex]1.0 \times10^-5 L[/tex]

P2 (final pressure) = 0.275 atm

V2 (final volume) = ? (in L)

Putting the values in the equation

[tex]\rm 2.0 \times10^6 atm \times 1.0 \times10^-5 L = 0.275 atm \times V_2\\\\V_2 = \dfrac{20}{0.275} = 72.72 L[/tex]

Thus, the volume is 72.72 L.

Most organisms on Earth are multi-celled." is false

Explanation:

In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Survival of the eukaryotes depends upon interactions between many cell types, and it is essential that a balanced distribution of types be maintained. This is achieved by the highly regulated process of cell proliferation. The growth and division of different cell populations are regulated in different ways, but the basic mechanisms are similar throughout multicellular organisms.

Answer:less than

Explanation:

If we had 79.3 grams of Xe, we would expect a volume that is less than obtained with neon. So, the correct option is (C).

Density is defined as the mass per unit volume of a substance. The most commonly used symbol for density is ρ, although the Latin letter d can also be used. Density is defined as mass divided by volume:

[tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]

where ρ is density,

m is mass, and

V is volume.

The mass contained per unit volume of an object is known as density. where the SI unit of density is kilogram per cubic meter [tex](kg/m^3).[/tex] Density is inversely proportional to volume, so the density of Xenon is [tex]5.894 kg/m^3[/tex] while the density of neon is 0.89994 kg/m³. So, if density is more than volume will be less and vice versa. In this case, density of Xenon is more as compare to neon so, the volume of neon will be more.

Thus, if we had 79.3 grams of Xe, we would expect a volume that is less than obtained with neon. So, the correct option is (C).

An acid can also be thought of as a chemical that can neutralize a base. Similarly, a base can neutralize an acid.

Acids turn litmus paper red, while bases make litmus paper turn blue.

Some examples of acids are sulfuric acid, hydrochloric acid, nitric acid, and so on. Some examples of bases are sodium hydroxide, potassium hydroxide, and so on.

Acids generally taste sour, while bases have a bitter taste.

Alkalis are the bases that are water-soluble, which means that they dissolve in water. In other words, not all bases are water-soluble, and only the water-soluble bases are known as alkalis. An example of an alkali is sodium hydroxide. It is a base because it can neutralize an acid, and because it is water-soluble, it is an alkali. An example of a base that is not alkali is copper oxide. This chemical can neutralize an acid, but it is insoluble in water.

In other words, all alkali are bases but not all bases are alkalis.

Also, an alkali has a hydroxide group, while a base has an oxide group in it.

Answer: i gotcu the answer is mass

Explanation: The more weight of the object the more its subject to gravity like a feather barley is while a bowling ball smashes into the ground :D

The property allows objects to be subject to gravity is mass. Therefore, option B is correct.

Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term.

The strength of an object's gravitational attraction to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit. The amount of matter object present is also known as mass.

The amount of matter that makes up every item or body is the greatest way to understand mass. Everything that we can see has mass. Examples of objects with mass include a table, a chair, your bed, a football, a glass, and even air. The mass of a thing determines whether it is light or heavy.

Thus, option B is correct.

By considering the world's complexity in terms of links and entire rather than breaking it down into its component components, systems thinking helps us make sense of how complicated the world is. It has been applied as a method for investigating and producing efficient action in challenging situations.

By using a deeper grasp of the surrounding structure and its constituent parts rather than relying just on previous events, systems thinking gives a technique to more accurately forecast future outcomes.

Systems thinking is a discipline in management that focuses on understanding a system by looking at the connections and interactions between the different parts that make up the entire of that defined system. The concept of the "entire system" is a way of looking at an entire organization in relation to its surroundings.
