Answer:

0.120M is the concentration of the solution

Explanation:

Assuming the mass of sodium nitrate dissolved was 2.552g

Molar concentration is an unit of concentration widely used in chemsitry defined as the moles of solute (In this case NaNO3) in 1L of solution.

To find this question we must find the moles of NaNO3 in 2.552g. With this mass and the volume (250mL = 0.250L) we can find molar concentration as follows:

Moles NaNO3 -Molar mass: 84.99g/mol-

2.552g * (1mol / 84.99g) = 0.0300 moles NaNO3

Molar concentration:

0.0300 moles NaNO3 / 0.250L =

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.

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:

[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].

Based on this information,  air​ has the lowest density. Therefore, the correct option is option D.

The substance's mass every unit of volume is known as its density. Although the Roman letter D may also be used, the sign most frequently used for density.  Density is calculated mathematically by dividing mass by volume.

Where m is the mass, V is the volume, and is the density. Density is sometimes roughly characterized as weight every unit volume, while this is incorrect technically; this quantity is much more precisely known as specific weight.  Air​ has the lowest density.

Therefore, the correct option is option D.

Explanation:

Answer: The volume of nitrogen gas at STP is 44.8 L.

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation for it follows:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]                    ...(1)

We are given:

Given mass of [tex]NaN_3[/tex] = 130.0 g

Molar mass of [tex]NaN_3[/tex] = 65.01 g/mol

Using equation 1:

[tex]Moles of NaN_3=\frac{130.0 g}{65.01g/mol}=2mol[/tex]

For the given chemical equation:

[tex]2NaN_3(s) \rightarrow 2Na(s) + 3N_2(g)[/tex]

By the stoichiometry of the reaction:

2 moles of [tex]NaN_3[/tex] produces 3 moles of nitrogen gas

At STP:

1 mole of a gas occupies 22.4 L of volume

So, 2 moles of nitrogen gas will occupy [tex]=\frac{22.4L}{1mol}\times 2mol=44.8L[/tex] of volume

Hence, the volume of nitrogen gas at STP is 44.8 L.

Explanation:

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.

Answer:

The empirical formula of the compound is [tex]C_{0.504}HO_{1.008}[/tex].

Explanation:

We need to determine the empirical formula in its simplest form, where hydrogen ([tex]H[/tex]) is scaled up to a mole, since it has the molar mass, and both carbon ([tex]C[/tex]) and oxygen ([tex]O[/tex]) are also scaled up in the same magnitude. The empirical formula is of the form:

[tex]C_{x}HO_{y}[/tex]

Where [tex]x[/tex], [tex]y[/tex] are the number of moles of the carbon and oxygen, respectively.

The scale factor ([tex]r[/tex]), no unit, is calculated by the following formula:

[tex]r = \frac{M_{H}}{m_{H}}[/tex] (1)

Where:

[tex]m_{H}[/tex] - Mass of hydrogen, in grams.

[tex]M_{H}[/tex] - Molar mass of hydrogen, in grams per mole.

If we know that  [tex]M_{H} = 1.008\,\frac{g}{mol}[/tex] and [tex]m_{H} = 0.2\,g[/tex], then the scale factor is:

[tex]r = \frac{1.008}{0.2}[/tex]

[tex]r = 5.04[/tex]

The molar masses of carbon ([tex]M_{C}[/tex]) and oxygen ([tex]M_{O}[/tex]) are [tex]12.011\,\frac{g}{mol}[/tex] and [tex]15.999\,\frac{g}{mol}[/tex], then, the respective numbers of moles are: ([tex]r = 5.04[/tex], [tex]m_{C} = 1.2\,g[/tex], [tex]m_{O} = 3.2\,g[/tex])

Carbon

[tex]n_{C} = \frac{r\cdot m_{C}}{M_{C}}[/tex] (2)

[tex]n_{C} = \frac{(5.04)\cdot (1.2\,g)}{12.011\,\frac{g}{mol} }[/tex]

[tex]n_{C} = 0.504\,moles[/tex]

Oxygen

[tex]n_{O} = \frac{r\cdot m_{O}}{M_{O}}[/tex] (3)

[tex]n_{O} = \frac{(5.04)\cdot (3.2\,g)}{15.999\,\frac{g}{mol} }[/tex]

[tex]n_{O} = 1.008\,moles[/tex]

Hence, the empirical formula of the compound is [tex]C_{0.504}HO_{1.008}[/tex].

Answer:

Methane is made up discrete molecules hence it adopts a simple molecular structure with weak vanderwaals forces of attraction while Silicon dioxide adopts a giant covalent structure with strong silicon to oxygen bonds.

Hence Silicon dioxide has a high melting point than methane.

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.
