Answers

Answer 1

Answer:

A. formation of snow

Explanation:

The formation of snow is an example of interactions between the atmosphere and hydrosphere.

As snow formation takes place when water vapor converted into liquid through condensation in the clouds. As water droplets rises high in clouds, cooler air present in atmosphere allow to lower the temperature and water droplets form ice or snow.

Hence, the correct option is A.

Which type of reaction is described by the following equation Na2O (s) + 2CO2 (g) + H2) (g) Produces 2 NaHCO3 (s)

Answers

Answer:

If the reaction is going from left to right it would be synthesis, if going right to left it would be decomposition.

Explanation:

Na2O (s) + 2CO2 (g) + H2O (g) = 2 NaHCO3 (s)

Left Side

Na = 2

O = 6

C = 2

H = 2

Right Side

Na = 2

O = 6

C = 2

H = 2

Ok so is balanced already, though initial equation in question had an error in regards to the left hand side the ) should have been an O.

Hmm

Na2O (s) + 2CO2 (g) + H2O (g) = 2 NaHCO3 (s)

If it was going from right to left would be decomposition

But going from left to right it would be synthesis

Calculate Rations. A transformer has ten turns of wire on the input side and 50 turns of wire on the output side. if the input voltage is 120 V, what will the output voltage be?

Answers

Answer:

Output voltage = 600 V

Explanation:

Using the transformer equation which simply states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.

Number of input turns/Number of output turns = Voltage of input/voltage of output

10/50 = 120V/voltage of output

Voltage of output = 120 V/0.2

Voltage of output = 600 V

We will need a chemical equation with masses and molar masses, so, let's gather all the information in one place.

Mᵣ:     65.38

              Zn + … ⟶ ZnO  + …

m/g:   275

(a) Moles of Zn

[tex]\text{Moles of Zn} = \text{275 g Zn}\times \dfrac{\text{1 mol Zn}}{\text{65.38 g Zn}} = \text{4.206 mol Zn}[/tex]

(b) Moles of ZnO

A saturated solution of sulfur dioxide is prepared by dissolving SO2(g) in 100. g of water at 10.°C and standard pressure.
Determine the mass of SO2 in this solution.
A.) 15g to 18g
B.) 40g to 43g
C.) 53g to 56g
D.) 6g to 8g

Answers

Answer:

The correct option is;

A.) 15 g to 18 g

Explanation:

The solubility of sulfur dioxide at room temperature = 94 g/L of water forming sulfurous acid as follows;

SO₂ + H₂O ⇄ HSO₃⁻ + H⁺

Which is a partial reversibly association with water molecules

Whereby 1 liter of water weighs 1 kg

9.4 gram of SO₂ will dissolve in 100 g of water at room temperature of 23 to 24°C

The solubility increases as the temperature reduces therefore as shown from the sulfur dioxide solubility chart we have;

At 10°C the solubility of SO₂ (g) is midway between 150 g to 200 g per kg of water

Therefore;

The solubility of SO₂ (g) is between 15 g to 18 g per 100 of water.

The mass of SO2 in the given solution should be an option a 15g to 18g.

Calculation of the mass:

Since the solubility of sulfur dioxide at room temperature = 94 g/L of water forming sulfurous acid likewise:

SO₂ + H₂O ⇄ HSO₃⁻ + H⁺

This represents the partial reversibly association along with water molecules

Here 1 liter of water weighs 1 kg

So we can say that

9.4 gram of SO₂ will dissolve in 100 g of water at room temperature of 23 to 24°C

Due to this, there is an increase in solubility this result in decrease in the temperature

Also, At 10°C the solubility of SO₂ (g) is midway between 150 g to 200 g per kg of water

Based on the Lewis/electron dot representation

cationic (+) atom to nonmetal anionic (-) atom in the compound

Answers

Answer:

A. 1:3

Explanation:

If we look at the ions shown in the image attached to the question, we will notice that we have aluminum (Al^3+), a trivalent ion combining with the iodide ion (I^-).

Aluminum can easily give out its three outermost electrons to three atoms of iodine. If aluminum gives out its three electrons, it achieves the stable octet structure. Iodine atoms have seven electrons in their outermost shell. They only need one more electrons to complete their octet. This one electron can be gotten by the combination of three iodine atoms with one atom of aluminum. One electron each is transferred from the aluminum atom to each iodine atom to form AlI3 with a ratio of 1:3.

Lewis dot structure is a diagrammatic representation of valence electrons in an atom of a molecule.

The ratio of the cations to anions in the given compound is 1:3.

In the given figure, Aluminum has 3 electrons, which can be donated to iodine. Aluminum has atomic number 13, this means that if the element donates three electrons then it will attain a stable electronic configuration.

In the Iodine atom, each iodine needs only one electron to complete its octet. Thus, three atoms of iodine will be required to gain electrons from aluminum.

Thus, the ratio cation to the anion is 1:3.

John Dalton was the chemist that gave the theory of atoms. His atomic model was incorrect as he said that the atoms cannot be further divided, but they are made of smaller particles. Thus, option D is correct.

What is Dalton's atomic model?

Dalton's atomic model stated that all matter is composed of atoms that are made of elements with identical properties and mass. He further stated the formation of the compounds from the molecules.

In the theory, he stated that atoms cannot be divided further and are indivisible. This was proven wrong as the atoms are composed of sub-atomic particles namely, electrons, neutrons, and protons.

Therefore, the statement that atoms are indivisible in Dalton's atomic theory is incorrect.

Answer:

15. 2.66 moles .

16. 2.09L.

Explanation:

Molarity of a solution is simply defined as the mole of solute per unit litre of the solvent. Mathematically, it is represented as:

Molarity = mole /Volume.

With the above formula, let us answer the questions given above

15. Data obtained from the question include the following:

Volume of solution = 1.4L

Molarity = 1.9M

Mole of solute =.?

Molarity = mole /Volume

1.9 = mole / 1.4

Cross multiply

Mole = 1.9 x 1.4

Mole = 2.66 moles

Therefore, the mole of the solute present in the solution is 2.66 moles.

16. Data obtained from the question include the following:

Mole of solute = 0.46 mole

Molarity = 0.22M

Volume of solvent (water) =.?

Molarity = mole /Volume

0.22 = 0.46/Volume

Cross multiply

0.22 x Volume = 0.46

Divide both side 0.22

Volume = 0.46/0.22

Volume = 2.09L

Therefore, 2.09L of water is required.

The manager in the Executive Office says that his network connection has gone down frequently over the past few days. He replaced his Ethernet cable, but the connection problem has continued. Now his network connection is either down or very slow at all times. He wants you to install a new 1000 Mbps Ethernet network card in his workstation to see if that solves the problem. If the new card does not resolve the issue, you will need to perform troubleshooting tasks to find the cause of the issue and confirm that the problem is fixed after you implement a solution. Following are some troubleshooting tasks you can try: Use the Network and Sharing Center and the ipconfig command on the Exec workstation to check for a network connection or an IP address. Look at the adapter settings to see the status of the Ethernet connection. Use the ping command to see if the workstation can communicate with the server in the Networking Closet. (See the exhibit for the IP address.) View the network activity lights for all networking devices to check for dead connections. In this lab, your task is to complete the following: 1. Install a new Ethernet adapter in one of the open slots in the Exec workstation per the manager's request. 2. Make sure that the new adapter is connected to the wall outlet with a cable that supports Gigabit Ethernet. 3. Resolve any other issues you find using the known good spare components on the Shelf to fix the problem and restore the manager's internet connection. After you replace the network adapter and resolve the issues you found while troubleshooting, use the Network and Sharing Center to confirm that the workstation is connected to the network and the internet If necessary, click Exhibits to see the network diagram and network wiring schematics. please help me!!!!!!!! if the temperature of your ice is 32 percent Fahrenheit and your water is 68 Fahrenheit and you mixed the ice and the water together what temperature is your water?
