Based on what you have learned about currents, how do you think this mass of trash ends up in the Great Pacific Garbage Patch?
Looking at the map, what ideas do you have about why the trash is "trapped" in this location?

Answer:

Answer:

The mole ratio of C₄H₁₀ and CO₂ is 2 : 8, which  simplifies to 1 : 4.

Explanation:

The mole ratio is the relative proportion of the moles of products or reactants that participate in the reaction according to the chemical equation.

The chemical equation given is:

2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O

Once you check that the equation is balanced, you can set the mole ratios for all the reactants and products. The coefficients used in front of each reactant and product, in the balanced chemical equation, tells the mole ratios.

In this case, they are: 2 mol C₄H₁₀ :  13 mol O₂ : 8 mol CO₂ : 10 mol H₂O

Since you are asked about the mole ratio of C₄H₁₀ and CO₂ it is:

2 mol C₄H₁₀ : 8 mol CO₂ , which dividing by 2, simplifies to

1 mol C₄H₁₀ : 4 mol CO₂, or

1 : 2.

Explanation: I just took the test and got it right.

Answer:

In neutral atom number of electrons (negativity charged particle) and number of proton ( positively charged particle) are equal.

When one or more electrons are lost so positive charge particle increases and cation is formed.

For example in Na 11 electrons and 11 protons are present when it loses one electrons protons are 11 and 10 electron are remaining so one positive charge is present.

Morever when an element gain electrons one negative charge increases and anion is formed. For example in Cl 17 proton and 17 electrons are present when it gain one electron 18 electrons and 17 protons are now present one negative is more so anion negative ion is formed.

Answer:

354 gram

Explanation:

No of formula units = no of moles × Avogadro's number

Number of moles = no of formula units/ Avogadro's number

No of moles = 1.30×10^24/60.02×10^23

No of moles = 2.159 moles

Mo of moles = mass in gram/ molar mass

Mass in gram = no of moles× molar mass

Mass in gram =2.159×164

Mass in gram = 354.15 gram

The grams that are present in [tex]1.30 * 10^{24}[/tex] formula units of [tex]Ca(NO_3)_2[/tex] is 354 gram that can be calculated using number of moles.

(B) 354 g

A mole is defined as [tex]6.02214076 * 10^{23}[/tex] of some chemical unit, be it atoms, molecules, ions, or others.

No. of formula units = no of moles × Avogadro's number

Number of moles = no of formula units/ Avogadro's number

No. of moles = [tex]1.30*10^{24}/6.022*10^{23}[/tex]

No. of moles = 2.159 moles

The Number of moles is defined as the given mass over molar mass.

No. of moles = Mass / Molar mass

Mass = no. of moles× molar mass

Mass =2.159×164

Mass = 354.15 gram

Thus, option B is correct.

Answer:

sodium, Na

Explanation:

Na, is the smallest with atomic number 11 and it has one valence electron

Answer:

A. H2O

Explanation:

Let us first define the three types of bonds:

1. Nonpolar Covalent: electronegativity difference < 0.4

2. Polar Covalent: electronegativity difference between 0.4 and 1.8

3. Ionic: electronegativity difference > 1.8

This will help us eliminate choices C and D:

-NaCl has a electronegativity difference of 3.0 - 0.9 = 2.1 (ionic bond)

-Cl2 has a electronegativity difference of 3.0 - 3.0 = 0 (nonpolar covalent bond)

However, we still have two more options, A and B, but they are not diatomic for us to use the electronegativity differences with.

We must now consult their geometries. Because CO2 has a linear geometry (O=C=O), the two sides will cancel each other out, resulting in a nonpolar covalent bond. At this point, by process of elimination, we can already determine the answer to be A. H2O. We can verify this by looking at the geometry of H2O, which is bent (H-O-H; imagine the O is above the H's, I cannot draw it in this response). H2O's bent geometry classifies it as polar covalent; the electrons are slightly more attracted towards the O, the more electronegative element. Side note: this makes the O slightly more negative in charge, whilst the H's are slightly more positive in charge.

P.S. I apologize for not being able to draw and demonstrate that last paragraph, but I hope you get a general idea. You can search up the "H2O geometry" and "CO2 geometry" to get a better idea! :)

H₂O represents a nonpolar molecule containing polar covalent bonds. Hence Option (A) is correct

A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond.

Consider the hydrogen chloride (HCl) molecule. Each atom in HCl requires one more electron to form an inert gas electron configuration.

Water (H₂O), like hydrogen Chloride (HCl), is a polar covalent molecule. When we look at a diagram of water , we can see that the two hydrogen atoms are not evenly distributed around the oxygen atom

Water (H₂O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule.Thus, This is an example of polar covalent chemical bonding.

Therefore, H₂O represents a nonpolar molecule containing polar covalent bonds. Hence Option (A) is correct

As the amount of salt in water increases, the density of the water increases. The more particles present in unit volume the more densely packed the substance.

Density of a substance is the measure of its mass per unit volume. Density describes how closely its particles are  packed. Densely packing means more particles in a unit volume.

The density of water is 1 g/ml. However, when the salinity increases, the salt solution increases in density by the solute particles. If the density of an object is less than water, it will float on it. Objects denser than water will sink on water.

As the salinity increases, density of water increases, makes the surface tension also increases, which best illustrates what happens in dead sea. Hence, option b is correct.

[tex]\boxed {\boxed {\sf About \ 92.2 \ moles \ of \ Magnesium}}[/tex]

Explanation:

To convert from atoms to moles, we must Avogadro's number:

This number tells us the amount of particles (atoms, molecules, etc.) in 1 mole of a substance. In this case, it is atoms of magnesium in 1 mole.

Now, let's set up an expression using:

[tex]\frac {6.022 * 10^ {23} \ atoms \ Mg}{ 1 \ mol \ Mg}[/tex]

Multiply this by the given number of atoms.

[tex]5.55*10^{25} \ atoms \ Mg *\frac {6.022 * 10^ {23} \ atoms \ Mg}{ 1 \ mol \ Mg}[/tex]

Flip the fraction so the atoms of magnesium can cancel.

[tex]5.55*10^{25} \ atoms \ Mg *\frac { 1 \ mol \ Mg }{6.022 * 10^ {23} \ atoms \ Mg}[/tex]

[tex]5.55*10^{25} *\frac { 1 \ mol \ Mg }{6.022 * 10^ {23}}[/tex]

Multiply and condense this into 1 fraction.

[tex]\frac { 5.55*10^{25} \ mol \ Mg }{6.022 * 10^ {23}}[/tex]

[tex]92.1620724 \ mol \ Mg[/tex]

The original measurement had 3 significant figures, so our answer must have that many as well. For the number we calculated, that is the tenth place. The 6 in the hundredth place tells us to round the 1 to a 2.

It is about 92.2 moles of magnesium.

It measure the number of elementary entities of a given substance that are present in a given sample. 1.99 moles of glucose are present in 1.2 x 10²⁴  molecules.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. The stoichiometry represents the number of moles. Mole is directly proportional to the number of given molecules.

Given number of atoms= 3.01x10²³atoms

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

mole of glucose =given number of molecules of glucose ÷ 6.022×10²³(Avogadro number)

Substituting the values, we get

mole of glucose= 1.2 x 10²⁴÷6.02 x 10²³

mole of glucose= 1.99 moles

Therefore, 1.99 moles of glucose are present in 1.2 x 10²⁴  molecules.

Answer: Summer Solstice

In North America, around June 21, Earth tilts on its axis toward the Sun. This is called the summer solstice, and it is when the Northern Hemisphere has the most daylight of any time of the year. It is also when the Sun appears to be the highest in the sky, and it has its greatest angle to Earth.

The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator.
