18.1 multiplying polynomial expressions by monomials

Answers

The  act of Multiplying a polynomial by a monomial is an easy one. An example of this is given as Multiply x – y – z by -8x².

What are Polynomial Expressions?

Polynomials are regarded as the sums of specific terms of a given form k⋅xⁿ. Here, the k stand for any number and n stand for a positive integer.

To Multiply x – y – z by -8x².

One has to first Multiply each term of the polynomial x – y – z by making use of the monomial -8x².

⟹ -8x² * (x – y – z)

= (-8x² * x) – (-8x² * y) – (-8x² *  z)

Note that the * sign connote multiplication.

The next step is to add the like terms together;

The answer therefore is = -8x³ + 8x²y + 8x²z

What is the temperature of 12.20 mol of gas in a 18.35 l tank at 16.40 atm?

Answers

The temperature of the given mole and pressure of gas is 300.6K.

Given the data in the question;

Amount of gas; [tex]n = 12.20mol[/tex]Volume of gas; [tex]V = 18.35L[/tex]Pressure; [tex]P = 16.40atm[/tex]

Temperature; [tex]T = \ ?[/tex]

The Ideal Gas Law

The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that  pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature. It is expressed;

[tex]PV = nRT[/tex]

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( [tex]0.08206Latm/molK[/tex] 0

The determine the temperature of the gas, we substitute our given values inro the equation above.

[tex]PV = nRT\\\\T = \frac{PV}{nR}\\ \\T = \frac{16.40atm\ *\ 18.35L }{12.20mol\ * \ 0.08206Latm/molK} \\\\T = \frac{300.94Latm}{1.001132molLatm/molK} \\\\T = 300.6K[/tex]

Explanation:

You work every saturday from 9:00 a.m. to 5:00 p.m. find the measure of the angle generated by the hour hand of a clock during this time in both degrees and radians. compare this angle with the angle generated by the minute hand from 9:00 a.m. to 5:00 p.m.

Answers

The angle generated by the hour hand measures -270° or -4.71 radians, and we will see that the angle generated by the minute hand is 12 times the one generated by the hour hand.

How to get the angle generated?

Remember that in a complete rotation we have an angle of 360°, and in a complete rotation we have 12 hours, then there is a relation:

12 hours = 360°

1 hour = 360°/12 = 30°

From 9:00 a.m to 5:00 p.m. there are 9 hours, so the angle that the hour hand does is:

A = 9*(30°) = -270°

(the negative sign is because this angle is measured clockwise)

Now we can write this in radians, remember that:

3.14 radians = 180°

Then:

1 = (3.14 rad/180°)

Then:

270° = -270°*(3.14 rad/180°) = -4.71 rad

What is the angle generated by the minute hand?

Each hour that passes, the minute hand does a complete revolution. Then in 9 hours, the minute hand does an angle of:

A = 9*(-360°) = -3,240°

To compare this angle to the one generated by the minute hand we take the quotient:

-3,240°/-270° = 12

So this angle generated by the minute hand is 12 times the one generated by the hour hand.

The element that would be the most effective at accepting electrons from another reagent is

Answers

Answer:

Matching the elements to the appropriate blanks as follows :

1) The element that would most effective at accepting electrons is ; CI

2) The element that would be the best insulator is ; Cl

3) The element best to form an ionic compound with sulfur is ; Rb

The acceptance of electrons by elements depends on the electronegativity of the element. from the options listed the element with the highest level of electronegativity is Cl ( chlorine ) therefore it the most effective at accepting electrons

Cl ( chlorine) is a non metal and non-metals are semi-conductors or insulators. therefore Cl would act as the best insulator when compared to other elements.

when metals react with non-metals they form an ionic compound. for sulfur the best metal to react with it is Rb ( soft silvery metal ) and the reaction of Rb and sulfur in hydrogen gas. results in Rb₂S₅

Hence we can conclude Matching the elements to the appropriate blanks as follows : The element that would most effective at accepting electrons is ; CI, The element that would be the best insulator is  Cl ,The element best to form an ionic compound with sulfur is ; Rb

Answers

The reaction rate between 0 -195 seconds for the decomposition of N2O5 is 0.0006 M/s.

What is the rate of a reaction?

The rate of reaction can be estimated in terms of the consumption of the reactants in the reaction.

From the given information, the equation N2O5 has been the reactant that has been used in 2 moles.

The rate of the reaction is expressed as:

[tex]\mathbf{Reaction \ rate = -\dfrac{1}{2} \times \dfrac{dN_2O_5}{dt}}[/tex]

The reaction rate for a time interval between (0 - 195) sec is expressed as follows:

[tex]\mathbf{Reaction rate = -\dfrac{1}{2} \times \dfrac{1.86556-2.10195}{195s - 0s}}[/tex]
