(40) The difference of squares of two numbers is 180. The square of the smaller number is 8 times the larger number. Find
the two numbers.

Answers

Question:-

The difference of squares of two numbers is 180. The square of the smaller number is 8 times the larger number. Find the two numbers.

Solution:-

Let the larger number be x

And, the square of the smaller number be 8x

ATQ ,

x² − 8x = 180

⇒ x² − 8x − 180 = 0

⇒ x² − (18 − 10)x − 180 = 0

⇒ x² − 18x + 10x − 180 = 0

⇒ x (x − 18) + 10(x − 18) = 0

⇒ (x − 18) (x + 10) = 0

⇒ x − 18 = 0, x + 10 = 0

⇒ x = 18, x = −10

⇒ x = −10, 18

[tex] \therefore [/tex] Either, x = −10 and x = 18

x = 18 (Positive value)

Now, the square of the smaller number = 8x = 8 × 18 = 144

So, the square of the smaller number = [tex]\sqrt{144} [/tex] = 12

The two numbers are 18 and 12. [Answer]

What is the specific heat of a 22.8 g sample of metal that absorbs 1,450 Joules of heat from 21.8 degrees Celsius to 75.0 degrees Celsius?

Answers

Answer: The specific heat of given metal is [tex]1.195 J/^{o}C[/tex].

Explanation:

Given: Mass of sample = 22.8 g

Heat energy = 1450 J

Initial temperature = [tex]21.8^{o}C[/tex]

Final temperature = [tex]75^{o}C[/tex]

Formula used to calculate the specific heat is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m = mass of substance or sample

C = specific heat

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\1450 J = 22.8 g \times C \times (75 - 21.8)^{o}C\\C = \frac{1450 J}{22.8 \times 53.2^{o}C}\\= 1.195 J/^{o}C[/tex]

Thus, we can conclude that the specific heat of given metal is [tex]1.195 J/^{o}C[/tex].

2 Na + Cl2 --> 2 NaCl
What is the mole ratio of sodium to sodium chloride?

Answers

Answer: The mole ratio of sodium to sodium chloride 2:2.

Explanation:

As the given reaction equation is as follows.

[tex]2Na + Cl_{2} \rightarrow 2NaCl[/tex]

Here, 2 moles of sodium reacts with 1 mole of [tex]Cl_{2}[/tex] and leads to the formation of 2 moles of NaCl.

This means that 2 moles of sodium gives 2 moles of NaCl on reaction with chlorine.

Hence, the ratio of moles of sodium to sodium chloride is 2:2.

Thus, we can conclude that the mole ratio of sodium to sodium chloride 2:2.

An ideal gas is held in a rigid container at temperature of 201∘C. Upon cooling the gas, the pressure decreases by a factor of 2.0, while the volume and the amount of gas remain constant. What must be the final temperature of the gas?

Answers

Answer:

237 K

Explanation:

Given that,

Initial temperature, T₁ = 201⁰C = 474 K

Let P be the initial pressure. Upon cooling the gas, the pressure decreases by a factor of 2.0, while the volume and the amount of gas remain constant.

Final pressure = P/2

The relation between the pressure and temperature is as follows :

[tex]\dfrac{P_1}{P_2}=\dfrac{T_1}{T_2}[/tex]

Put all the known values,

[tex]\dfrac{P}{\dfrac{P}{2}}=\dfrac{474}{T_2}\\\\2=\dfrac{474}{T_2}\\\\T_2=\dfrac{474}{2}\\\\T_2=237\ K[/tex]

So, the final temperature of the gas is equal to 237 K.

What is the molarity of a solution in which 175.8
grams of NaCl is dissolved in 1.5 L of water?

Answers

175.8 g NaCl to moles:
(175.8 g)/(58.44 g/mol) = 3.008 mol NaCl

Molarity = moles of solute/volume of solution in liters

(3.008 mol NaCl)/(1.5 L) = 2.0 M.

The molarity of this solution would be 2.0 M.

pb(No3)2(aq) +2KCI(aq)---PbCl2(s)+KNO2(aq). how many grams of PbCl2 solution will react with a 0.46 L of a 0.101m KCI solution​

Answers

Answer:

6.3986g

Explanation:

The balanced chemical equation of this reaction is as follows:

Pb(NO3)2(aq) + 2KCl (aq) → PbCl2(s) + 2KNO3(aq)

In this equation, 2 moles of KCl solution will produce 1 mole of PbCl2.

To calculate the number of moles of PbCl2 produced, we use the formula:

Molarity = number of moles (n) ÷ volume (V)

0.101 = n/0.46

n = 0.046mol of KCl

If 2 moles of KCl solution will produce 1 mole of PbCl2

Then, 0.046mol of KCl will be react to produce (0.046 × 1/2) of PbCl2

0.046 × 1/2 = 0.023mol of PbCl2

To find the mass of PbCl2 using mole = mass ÷ molar mass

Molar mass of PbCl2 = 207.2 + 35.5(2)

= 207.2 + 71

= 278.2g/mol

0.023 = mass/278.2

mass = 6.3986g

Answers

Mass number = number of protons + number of neutrons

The number of protons in the nucleus of an atom of phosphorus is equal to the atomic number of phosphorus, which is 15. If an atom of phosphorus has 17 neutrons, then the mass number would be 15 protons + 17 neutrons = 32. Thus, the correct answer choice here is B.

The brightness of a light correlates to its amplitude. The higher the amplitude, the brighter the light will appear. Which of the waves below depicts the brightest light?

Answers

Answer:

Wave X is the brightest light

Explanation:

The amplitude of a wave refers to the maximum upward or downward displacement of a wave from its rest position. This implies that the amplitude is the measured distance from rest position to crest position. Similarly, the amplitude is also measured from the rest position to the trough position.

The crest of a wave is the point on a travelling wave that has the maximum amount of positive or upward displacement from the rest position. The trough of a wave is the point on the travelling wave that has the maximum amount of negative or downward displacement from the rest position.

From the wave diagrams shown in the attachment below, the wave that shows the highest amount of upward or downward displacement from the rest position (x - axis) is wave X. Since the brightness of a light wave increases with increaese in amplitude, wave X will have the highest amount of brightness.

Molarity = moles of solute/volume of solution in liters.

The solute here is NaCl, of which we have 46.5 g. To calculate the molarity of an NaCl solution, we need to know the number of moles of NaCl. To convert from grams to moles, we divide the mass by the molar mass of NaCl. The molar mass of NaCl is the sum of the atomic masses of Na and Cl: 23 amu + 35 amu = 58 amu. For our purposes, we can regard amu as equivalent to grams/mole.

(46.5 g)/(58 g/mol) = 0.8017 moles NaCl.

Now that we know both the number of moles of our NaCl solute and the volume of the solution, we can calculate the molarity:

(0.8017 moles NaCl)/(2.2 L) = 0.364 M.

Answers

Answer:

24.2 mL.

Explanation:

Assuming constant temperature, we can solve this problem using Boyle's law, which states:

P₁V₁=P₂V₂

Where:

P₁ = 0.98 barV₁ = 25 mLP₂ = 1.013 barV₂ = ?

We input the data:

0.98 bar * 25 mL = 1.013 bar * V₂

And solve for V₂:

V₂ = 24.18 mL

The closest option is the second one: 24.2 mL.
