if an ionic bond forms between an atom of al and an atom of n, how many valance electrons are transferred? 3 4 1 2

Answers

Answer 1

In the formation of an ionic bond between Al and N, 3 valence electrons are transferred from the aluminum atom to the nitrogen atom.

When an ionic bond forms between an atom of Al (aluminum) and an atom of N (nitrogen), the transfer of electrons occurs to achieve a stable electron configuration.

Aluminum (Al) has 3 valence electrons in its outermost energy level, while nitrogen (N) has 5 valence electrons.

To achieve a stable electron configuration, aluminum tends to lose 3 electrons to attain a full outer shell, becoming a positively charged ion, Al³⁺.

On the other hand, nitrogen tends to gain 3 electrons to complete its outer shell, becoming a negatively charged ion, N3⁻.

Equal forces acting on one object in opposite directions are called balanced forces

Answers

Answer:

True

Explanation:

Forces, equal in magnitude and opposite in direction, and cancel each other out are called Balanced Forces.

Balanced Forces DO NOT cause any change in the velocity of the object, but the Object may correspond to a change in shape or size.

Example :

Blasting a balloon by compressing it tightly with both hands, roughly with an equal force, is a practical example of Balanced Forces. In this case, the balloon before the burst stays at a state of rest and same after the burst. But the burst or the compression, causes a change in the shape of the balloon.

How many grams of magnesium are needed to make 350 grams of silver?

Answers

Answer:

First, we need to determine the molar ratio between magnesium (Mg) and silver (Ag) in the balanced chemical equation:

1 mol Mg : 2 mol Ag

This means that for every one mole of magnesium that reacts, two moles of silver are produced.

Next, we need to calculate the number of moles of silver that can be produced from 350 grams of silver:

mass of silver = 350 g

molar mass of silver = 107.87 g/mol

moles of silver = mass of silver / molar mass of silver

moles of silver = 350 g / 107.87 g/mol

moles of silver = 3.24 mol Ag

Now, we can use the mole ratio to determine the number of moles of magnesium required to produce 3.24 moles of silver:

1 mol Mg : 2 mol Ag

moles of Mg = moles of Ag / 2

moles of Mg = 3.24 mol Ag / 2

moles of Mg = 1.62 mol Mg

Finally, we can use the molar mass of magnesium to convert the number of moles to grams:

molar mass of Mg = 24.31 g/mol

mass of Mg = moles of Mg x molar mass of Mg

mass of Mg = 1.62 mol x 24.31 g/mol

mass of Mg = 39.3 g

Therefore, approximately 39.3 grams of magnesium are needed to produce 350 grams of silver.

Explanation:

Stoichiometry, which involves balancing the equation and using the molar mass of each substance, must be used to calculate how many grams of magnesium are required to make 350 grams of silver.

Firstly, balance the chemical equation:

Mg + 2AgNO₃ → Mg(NO₃)₂ + 2Ag

A mole of magnesium interacts with two moles of silver nitrate to form a mole of magnesium nitrate and two moles of silver, according to this equation. We can deduce from the balanced equation that the magnesium-to-silver ratio is 1:2.

Following that, we must determine the molar mass of silver:

Silver(Ag): 107.87g/mol

The requisite magnesium can then be calculated using the formula below:

Grams of Magnesium (Mg) = (molar mass of Ag x grams of Ag) / (2 x molar mass of Mg)

Grams of Magnesium (Mg) = (107.87 g/mol x 350 g) / (2 x 24.31 g/mol)

Grams of Magnesium (Mg) = 303.38 g

Thus, 350 grams of silver can be made from 303.38 grams of magnesium.

If 10 moles of P4S3 was used, how many grams of P4O6 was produced? Leave up to 3 decimal places when possible.

Answers

If 10 moles of P4S3 were used, the mass of P4O6 produced would be 2838.8 grams.

To determine the number of grams of P4O6 produced from 10 moles of P4S3, we need to use the balanced chemical equation and the molar masses of the compounds involved.The balanced equation for the reaction between P4S3 and oxygen to produce P4O6 is:

P4S3 + 8 O2 → P4O6 + 6 SO2

From the balanced equation, we can see that the molar ratio between P4S3 and P4O6 is 1:1. This means that for every 1 mole of P4S3 consumed, 1 mole of P4O6 is produced.The molar mass of P4S3 is 220.25 g/mol, and the molar mass of P4O6 is 283.88 g/mol.

To calculate the mass of P4O6 produced, we can use the following equation:

Mass of P4O6 = Moles of P4O6 × Molar mass of P4O6

Since the molar ratio between P4S3 and P4O6 is 1:1, the number of moles of P4O6 produced is also 10 moles.

Mass of P4O6 = 10 moles × 283.88 g/mol = 2838.8 grams

A 0.200 m K2SO4 solution has a freezing point of −0.53°C. What is the van't Hoff factor for this solution?

Kf = 1.86°C/m

Answers

To solve this problem, we can use the equation for the freezing point depression:

ΔTf = Kf * i * molality

where ΔTf is the change in freezing point, Kf is the freezing point depression constant (given as 1.86°C/m), i is the van't Hoff factor, and molality is the number of moles of solute per kilogram of solvent.

We are given that the freezing point depression is 0.53°C and the molality is:

molality = moles of solute / mass of solvent (in kg)

We don't have the mass of solvent, but we can assume that it is 1 kg (1000 g) since the molality is in moles per kilogram of solvent. This means that the mass of solute (K2SO4) is 0.200 * 1000 = 200 g.

The molar mass of K2SO4 is 174.26 g/mol, so the number of moles of solute is:

moles of solute = 200 g / 174.26 g/mol = 1.147 mol

Substituting these values into the freezing point depression equation, we get:

0.53 = 1.86 * i * (1.147/1)

Solving for i, we get:

i = 0.53 / (1.86 * 1.147) = 0.247

Therefore, the van't Hoff factor for this solution is approximately 0.247

the structures of d-gulose and d-psicose are shown above. what test could be used to distinguish between solutions of these two carbohydrates? explain your answer by predicting the results of the test for each sugar.

Answers

a small amount of Tollens' reagent (ammoniacal silver nitrate) is added to the sugar solution and the mixture is heated. If a reducing sugar is present, it will reduce the silver ions in the Tollens' reagent to metallic silver, which will form a silver mirror on the inside of the test tube.

Based on the structures of D-gulose and D-psicose, it can be predicted that both sugars will give a positive result in the Tollens' test because they both have an aldehyde group that can act as a reducing agent. However, the intensity of the reaction may differ for each sugar.

D-gulose has an aldehyde group at carbon 1, which is in the linear form of the sugar, while D-psicose has an aldehyde group at carbon 2. Since D-gulose can easily convert to its linear form, it is expected to give a stronger positive result in the Tollens' test compared to D-psicose, which may show a weaker positive result due to the steric hindrance of the bulky ketone group at carbon 3.

In summary, the Tollens' test can be used to distinguish between solutions of D-gulose and D-psicose by observing the intensity of the silver mirror formed. D-gulose is expected to give a stronger positive result due to its ability to convert to the linear form, while D-psicose may show a weaker positive result due to steric hindrance.

which theory explains how glacial material can be observed today near sea level at the equator, even though sea level glaciers probably never existed there

Answers

The theory that explains how glacial material can be observed today near sea level at the equator, even though sea level glaciers probably never existed there, is called glacial erratics.

Glacial erratics are large rocks that have been transported from their place of origin by glaciers and deposited far away. During the Pleistocene era, glaciers covered much of the earth, including areas near the equator. As these glaciers retreated, they left behind glacial erratics that can still be observed today. These rocks provide evidence of the extent of past glaciation and help scientists understand the history of the earth's climate.
The theory that explains the presence of glacial material near sea level at the equator is Plate Tectonics. This theory describes Earth's crust as being composed of large, moving plates that interact with one another. Over millions of years, these plates have shifted continents, leading to the distribution of glacial material in various locations, including equatorial regions. Glaciers likely formed at higher latitudes and altitudes during past ice ages, and as the plates moved, the glacial deposits were carried along, eventually reaching their current positions near sea level at the equator. This process demonstrates the dynamic nature of Earth's surface and its geological history.
