Answers

Answer:

Kingdom Monera.

Explanation:

The unicellular organisms the student observed were most likely from the Kingdom Monera because in this kingdom, unicellular organisms are included which are prokaryotic in nature. Monera is a Greek word means "single" is a kingdom that contains organisms that are made up of one cell and having a prokaryotic cell means having no nuclear membrane and we know that bacteria is also a unicellular organism and prokaryotic in nature.

An empty beaker weighs 20g and when filled with
Kensene weighs 60g. If the Volume of the kerosene is 15cm2 calculate
the density of the kerosene

Answers

Answer: The density of kerosene is [tex]2.7g/cm^3[/tex]

Explanation:

Density is defined as the mass contained per unit volume.

[tex]Density=\frac{mass}{Volume}[/tex]

Given : Mass of kerosene = mass of beaker with kerosene - mass of empty beaker = 60 g - 20 g = 40 g

Volume of kersone = [tex]15cm^3[/tex]

Putting in the values we get:

[tex]Density=\frac{40g}{15cm^3}[/tex]

[tex]Density=2.7g/cm^3[/tex]  

Thus the density of kerosene is [tex]2.7g/cm^3[/tex]

Which solution has the highest boiling point?
1.0 M KNO3
2.0 M KNO3
1.0 M Ca(NO3)2
2.0 M Ca(NO3)2

Answers

2.0 M Ca(NO3)2

First off, the greater the charge on your ions, the stronger the ion-dipole forces are between the ions and water molecules in solution. Ca2+ has a greater charge than K+. Also, the more concentrated the solution, the more ions you have, and therefore more ion-dipole forces overall. The stronger the intermolecular forces are, the higher the boiling point.

The highest boiling point has been of 2.0 M [tex]\rm Ca(NO_3)_2[/tex]. Thus, option D is correct.

The boiling point has been the temperature at which the liquid starts to be converted to the gases. The boiling point has been higher when the inter-molecular forces between the molecules are higher.

With high inter-molecular forces, there has been higher amount of energy required to break the bonds, and change the state. The boiling point has also been dependent on the concentration, as higher the molecules present, there has been higher bonds, and more energy is required.

The Ca molecules has charge +2, while K has +1, this states, the stronger bonding of Ca with nitrate as compared to the K. Thus, calcium nitrate solution of 2 M has requires more energy, and thus have the highest boiling point.

The highest boiling point has been of 2.0 M [tex]\rm Ca(NO_3)_2[/tex]. Thus, option D is correct.

Answers

Question: Calculate the mass of magnesium chloride you would need to dissolve in 4dm³ of water to

make a 0.9g/dm³ solution.

Answer:

3.6 g

Explanation:

From the question,

Density of magnesium (D) = Mass of magnesium (m)/Volume of magnesium(V)

D = m/V............... Equation 1

Make m the subject of the equation

m = D×V............. Equation 2

Given: D = 0.9 g/dm³, v = 4 dm³

Substitute these values into equation 2

m = 0.9×4

m = 3.6 g.

Hence the mass of magnesium is 3.6 g.

What volume of water is required to prepare 1.50M solution with 2.55 moles of NaCl?

Answers

Answer:

?

Explanation:

Molarity is the molar concentration of the moles in a solution. The volume of water required for preparing 1.50 M NaCl solution is 1.7 L.

What is volume?

Volume is the number of moles of solute present in a molar concentration of a solution.

Molar concentration is given as,

[tex]\rm Molarity (M) = \dfrac{\text{moles of solute}}{\text{litres of solution}}[/tex]

Given,

Molarity of sodium chloride = 1.50 M

Number of moles of sodium chloride = 2.55 mol

Substituting values in the above equation the volume is calculated as:

[tex]\begin{aligned}\rm Volume &=\rm \dfrac{moles}{molarity}\\\\&= \dfrac{2.55}{1.50}\\\\&= 1.7 \;\rm L\end{aligned}[/tex]

Therefore, 1.7 L of water is required.

What is the pH and pOH of a 2.34 x 10^-5 NaOH solution?

Answers

Answer:

pOH = 4.63

pH = 9.37

Explanation:

Because NaOH is a strong base, it will completely dissociate, which means you can find pOH by taking the negative log of the concentration of hydroxide ions: pOH = -log(OH) = -log(2.34 x 10⁻⁵) = 4.630784143

To find pH use 14.00 = pH + pOH

pH = 14.00 - 4.630784143 = 9.369215857

Introduction: The (fictitious) town of Solutionville is trying to figure out a way to replace their current coal-fired power plants with cleaner and more sustainable energy sources. At a recent town meeting, it was proposed that the town build a nuclear power plant to replace coal as the community’s main source of energy for electricity.



Your Challenge: As a voting citizen of Solutionville, you must decide whether or not you support building a nuclear power plant to provide energy and electricity to homes and businesses in the community. This means carefully weighing the benefits and disadvantages of nuclear power.



1. Conduct research to learn more about nuclear power, and keep track of what you learn on slide#4 and/or in your notebook.

2. Make sure to write down the sources you get your information from, and be ready to defend the sources as credible.

3. Using the information you find, fill in the Benefits and Drawbacks Chart on slide #5 3. Be prepared to defend the information on your chart with evidence from your sources.

4. Analyze your findings, then find a partner and compare notes.

5. Decide whether or not you are in favor of or opposed to nuclear energy.
