When paying off debt consider the interest rates. C., and D. are just facts.

In general, the larger the debt, the longer you should plan to take to pay it off. The correct option is a.

A debt payment plan is a way to pay off debts gradually. It usually entails consistent payments toward the balance due on each loan.

The total amount of debt, interest rates, minimum payments, and the time frame for repayment should all be taken into account while making a debt payment plan.

You can lower the amount of interest you pay over time by making a payment that is greater than what is required or anticipated in order to assist you pay off the debt sooner.

The longer it takes you to pay off your debt, the more vital it is to bear in mind.

In general, when making a debt payment plan, you shouldn't take into account the fact that the debt will take longer to pay off the larger it is.

Thus, the correct option is a.

Explanation:

Hello!

In this case, since Helium is undergoing a volume-pressure change, according the Boyle's law, we infer the following equation is used:

[tex]P_1V_1=P_2V_2[/tex]

Thus, since we are not given the volume at 0.25 atm, we can solve for V2 to do so:

[tex]V_2=\frac{P_1V_1}{P_2}[/tex]

Thus, we plug in to obtain:

[tex]V_2=\frac{1atm*30L}{0.25atm}=120L[/tex]

Best regards!

The final volume of the balloon at the given altitude is 120 L.

The given parameters;

The final volume of the balloon at the given altitude is calculated by applying Boyles law as follows;

[tex]P_1 V_1 = P_2 V_2\\\\V_2 = \frac{P_1V_1}{P_2} \\\\V_2 = \frac{30 \times 1 }{0.25} \\\\V_2 = 120 \ L[/tex]

Answer:

What you need to know before I explain is how to add percents onto numbers.  What I'm saying is what and how to do 6.4% x 1500

1. You can't do a percent and number together, that's impossible

What you can do is convert the percent (6.4%) into a decimal

2. 6.4% is equivalent to 6.4/100, which is equivalent to 0.064

3.  Now, you multiply 0.064 x 1500

You will notice, hopefully, that you have a number smaller than 1500, but do not panic, you are on the right track!

4. Using the number you got, add that to 1500, and there's your total!

But, if you want only the tax, keep that small number you started off with!

The structure of the table shows occasional (popular things/general ways things are going). The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with almost the same chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks connected with the filling of different atomic orbitals.

Answer:

[tex]\Delta S_{sys}=0.020kJ=20J[/tex]

Explanation:

Hello!

In this case, given the required energy to vaporize 1.00 mol of ethanol as the enthalpy of vaporization:

[tex]\Delta H_{vap}=\frac{38.6kJ}{1.00mol}=38.6kJ/mol[/tex]

We can compute the entropy of the system for the vaporization of 8.00 g of ethanol, by first computing the moles:

[tex]n_{et}=8.00g*\frac{1mol}{46.07g} =0.174mol[/tex]

And then setting up the following expression:

[tex]\Delta S_{sys}=\frac{n_{et}*\Delta H_{vap}}{T}[/tex]

Whereas the temperature is in kelvins; thus, we obtain:

[tex]\Delta S_{sys}=\frac{0.174mol*38.6\frac{kJ}{mol} }{79.6+273.15K}\\\\\Delta S_{sys}=0.020kJ=20J[/tex]

Best regards!

The entropy of the system ([tex]\Delta S_{sys}[/tex]) for the vaporization of 8.00 grams of ethanol at 79.6 °C is 0.0190 kilojoules.

Given the following data:

Conversion:

Temperature = [tex]79.6 + 273 = 352.6 \;K[/tex]

To find the entropy of the system ([tex]\Delta S_{sys}[/tex]) for the vaporization of 8.00 grams of ethanol at 79.6 °C:

First of all, we would determine the heat of vaporization.

[tex]Heat\; of \;vaporization = \frac{Energy}{moles} \\\\Heat\; of \;vaporization = \frac{38.6}{1}[/tex]

Heat of vaporization = 38.6 kJ/mol.

Next, we would determine the number of moles in 8.00 grams of ethanol:

[tex]Number\;of\;moles = \frac{mass}{molar\;mass}\\\\Number\;of\;moles = \frac{8}{46.07}\\\\Number\;of\;moles = 0.1737 \;moles[/tex]

Mathematically, the entropy of a system ([tex]\Delta S_{sys}[/tex]) is given by the formula:

[tex]\Delta S_{sys} = \frac{n\Delta H }{T}[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]\Delta S_{sys} = \frac{0.1737 \times 38.6 }{352.6}\\\\\Delta S_{sys} = \frac{6.7048 }{352.6}\\\\\Delta S_{sys} = 0.0190 \;kJ[/tex]

Answer:

A. In a polar molecule, the bond is polar covalent. That is, the electrons are shared but are slightly more attracted to the more electronegative atom. That part of the molecule has a negative partial charge density, and the other has a positive partial charge density (there is no symmetry in the distribution of the electricity density)

B. Charges are not affected, the molecule is neutral because electrons are shared. A molecule has the same number of electrons and protons which balance the charges in a molecule. Since all atoms are electrically neutral, then when they combine the form of a neutral molecule.

Explanation:

To determine polarity, the geometry of the molecule must be taken into account to determine the distribution of atoms and their electronegativity (tendency to attract electrons) to determine to which points of the molecule the electrons will be most attracted.

Atoms can share electrons to form chemical bonds and thus form different compounds. In the case of non-polar molecules, when formed in a covalent bond (two atoms bond by sharing valence electrons reaching "stable octet") between equal atoms, the molecule is neutral since it has zero electric charge. In this type of bond there is no change in the oxidation number of the atoms because their shared electrons are equidistant. Covalent bonds in which the electrons are shared equally are called non-polar covalent bonds. This is because the atoms are just the same, they have the same electronegativity, so they "attract" the electrons with the same force and the electrons surround the atoms equally. The charge density distribution is the same for both, there is asymmetry in the distribution of it.

Polar molecules are formed when bonds are formed by different atoms with large differences in electronegativity. The molecule is electrically neutral as a whole because it has an equal number of positive and negative particles, but there is no symmetry in the distribution of the electricity density. A polar bond is one in which a pair of electrons is more attracted to one of the atoms. This causes one end of the molecule to acquire a positive partial charge density and the other end of the molecule to acquire a positive partial charge density and the other end of the molecule to acquire a negative partial charge.

So, as a summary:

A. In a polar molecule, the bond is polar covalent. That is, the electrons are shared but are slightly more attracted to the more electronegative atom. That part of the molecule has a negative partial charge density, and the other has a positive partial charge density (there is no symmetry in the distribution of the electricity density)

B. Charges are not affected, the molecule is neutral because electrons are shared. A molecule has the same number of electrons and protons which balance the charges in a molecule. Since all atoms are electrically neutral, then when they combine the form of a neutral molecule. Only ions do not have a neutral electrical charge because of the process of gaining or losing electrons. An ion with a positive electrical charge is called a cation, and an ion with a negative electrical charge is called an anion.
