[tex]K_a=\frac{[H_2PO_4^-][H^+]}{[H_3PO_4]}[/tex]

K, the equilibrium constant, is equal to products over reactants raised to their coefficients (excluding solids and liquids and only including aqueous and gasses)

[tex]Ka=\frac{[H_2PO_4^- ][H^+]}{H_3PO_4}[/tex]  is the equilibrium constant and is equal to products over reactants raised to their coefficients (excluding solids and liquids and only including aqueous and gasses). Hence, option A is correct.

Among these, sodium chloride is a substance which is not a base, therefore option (b) is correct.

A base is a chemical species that donates electrons, accepts protons, or releases hydroxide (OH-) ions in aqueous solution. A base is a molecule or ion able to accept a hydrogen ion from an acid.

A strong base completely dissociates into its ions in water. Bases react vigorously with acids and organic matter. Bases react in predictable ways with pH indicators.

A base substance is  a solution that has a pH level of more than 7.  Bases react with acids to form salts which is called neutralization reaction.

Among these  since sodium chloride is not a base, hence option(b) is correct.

Answer:

[tex]d=0.417\ g/cm^3[/tex]

Explanation:

Given that,

Mass, m = 10 g

Volume, V = 24 cm³

We need to find the density of the substance. We know that, the density of a substance is given by :

Density = mass/volume

So,

[tex]d=\dfrac{10\ g}{24\ cm^2}\\\\d=0.417\ g/cm^3[/tex]

So, the density of the substance is [tex]0.417\ g/cm^3[/tex].

Answer: The law of conservation of mass is reffering to the fact that energy cannot be created or destroyed. So when you speak about atoms not being created or destroyed it is the same thing. Unless you're talking about an atomic bomb where the atoms are split.

In a chemical reaction, the total mass present is equal to the mass of all the atoms undergoing the reaction.

According to the law of conservation of mass, mass is neither created nor destroyed but can be converted from one form to another. In a chemical reaction, atoms are rearranged. However, the total number of atoms in the system remains constant.

So, the total mass present in the system is equal to the mass of all the atoms undergoing the reaction. Since atoms are only rearranged, no new atom is formed and no atom disappears in the reaction, the total mass of the system remains constant.

For this reason, the statement;  “In a chemical reaction, atoms are neither created nor destroyed, only rearranged" is a statement of the law of conservation of mass.

Explanation:

We want to know if 50 grams of iron (II) sulfide contains 3.011 * 10²³ molecules.  Let's calculated and check.

We know there are 50 grams of iron (II) sulfide or FeS If we want to convert from grams to moles, we use the molar mass (mass per 1 mole). This is given to us and it is 87.91 grams per mole for this substance. Let's create a ratio.

[tex]\frac {87.91 \ g \ FeS}{ 1 \ mol \ FeS}[/tex]

We want to convert 50 grams of FeS to moles, so we multiply by this value.

[tex]50 \ g \ FeS *\frac {87.91 \ g \ FeS}{ 1 \ mol \ FeS}[/tex]

Flip the ratio so the grams of FeS cancel.

[tex]50 \ g \ FeS *\frac {1 \ mol \ FeS}{ 87.91 \ g \ FeS}[/tex]

[tex]50*\frac {1 \ mol \ FeS}{ 87.91}[/tex]

[tex]\frac {50}{ 87.91} \ mol \ FeS[/tex]

[tex]0.5687635081 \ mol \ FeS[/tex]

1 mole of any substance contains the same number of particles (atoms, molecules, formula units, etc.). This is Avogadro's Number or 6.022 *10²³. In this case, the particles are molecules of FeS. Create another ratio.

[tex]\frac {6.022 *10^{23} \ molecules \ FeS}{ 1 \ mol \ FeS}[/tex]

We want to convert 0.5687635081 moles of FeS to molecules, so we multiply by this value.

[tex]0.5687635081 \ mol \ FeS*\frac {6.022 *10^{23} \ molecules \ FeS}{ 1 \ mol \ FeS}[/tex]

The units of moles of FeS cancel.

[tex]0.5687635081 *\frac {6.022 *10^{23} \ molecules \ FeS}{ 1 }[/tex]

[tex]0.5687635081 *{6.022 *10^{23} \ molecules \ FeS}[/tex]

[tex]3.42509385*10^{23} \ molecules \ FeS[/tex]

If we round to the thousandth place, the 0 in the tenth thousandth place tells us to leave the 5.

[tex]3.425*10^{23} \ molecules \ FeS[/tex]

50 grams of iron (II) sulfide is approximately 3.425 * 10²³ molecules, not 3.011 *10²³ so the statement is false.

The direction in which the wind will blow in this situation is from the ocean to the coast and is denoted as option A.

This is defined as the force per unit area of a body and the unit is Pascal. We were told that air pressure above a large body of water is higher than the air above the coast.

This will make the wind blow from the ocean to the coast as the ocean has a higher pressure.

Answer:

If a species cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered or extinct.

Explanation:

The way the question is worded, it sounds like there are options for you to chose from that you are not showing. I could help you out more if I actually knew the options.

Extinction is likely if conditions change faster than a species can evolve, and if members of that species lack the traits required to survive in the new environment.

The death of all members of a species of plants, animals, or other organisms is referred to as extinction.

The primary cause of higher extinction rates is habitat loss. Other causes include habitat changes, commercial overexploitation of wildlife, the introduction of harmful nonnative species, pollution, and disease spread.

If a species is unable to adapt to changes in its ecosystem, it may relocate. The species may become threatened, endangered, or extinct if they do not move.

Thus, Extinction is likely if environmental conditions change faster than a species can evolve and members of that species lack the traits needed to survive in the new environment.

Answer:

Large amount of gas can be stored in small container.

Explanation:

They are compressed so that a larger amount of gas can be stored in a smaller container. A greater mass confined to a smaller volume makes transporting and storing of gases easier. Increasing temperature increases pressure, and the cylinders might explode.

Answer:

the energy barrier that must be surmounted in order for the reactants to transform into products.

Explanation:

When we draw a reaction profile, there is always a hump that is found between the reactants and products. This hump is called the activation energy.

The activation energy of a reaction stands as a sort of barrier between reactants and products which must be surmounted before the reactants are converted into products.

Only reactants that possess the activation energy can be converted from reactants to products.

Radioactive elements are the elements into which an atom is very unstable or highly reactive because it is having more energy in its nucleus. stable elements are those who have stable and there shell are properly filled with electrons.

Most radioactive chemical elements have one or more radioactive isotopes on the other hand  some chemical elements only have one type of radioactive isotopes.

A radioactive element has an unstable nucleus that emits particles in the form of alpha, beta, or gamma radiation and stable element have stable nucleus with no effect of any radiation or energy due to fully filled orbitals.

Bombarding of these radiations has to be done in the nucleus of the element after this the desired element will become a radioactive element. And there is no effect of these rays on stable elements beacuse they are unreactive to this.

The ray of alpha beta and gamma consists of some charges within them and they are radioactive radiations harmful to human eyes.

Answer:

grass

Explanation:

Grass is at the very bottom of the food chain and relies solely on sunlight and water, which aren't organisms. I'm going to assume you meant prairie dog because a prairie isn't an organism, but prairie dogs rely on grass for food. Ferrets rely on meat for food (which they get from other animals) and foxes rely on other animals for food as well. Therefore, grass is the only organism that is a producer (gives other organisms food) and doesn't rely on other organisms for food.

Answer:

Grass

Explanation:

A producer or autotroph is an organism that produces its own food. These include plants, algae, and some bacteria. They convert carbon dioxide, water, and light energy from the sun into glucose, a type of sugar that provides energy, in the process of photosynthesis.

The organisms we are given are grass, prairie dog, ferret, and fox. The only plant is grass. Prairie dogs, ferrets, and foxes are all consumers, and depend on other organisms (plants, grass, leaves, or other animals for meat) for food.
