Calculate the molarity 14.1 moles of FeCl3 dissolved in 2350 ml of solution

Answers

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

We have 14.1 moles of FeCl3, which is the solute, and the volume of our solution is 2.350 liters. So, the molarity of the solution would be (14.1 moles FeCl3)/(2.350 L solution) = 6 moles/L FeCl3 or 6 M FeCl3.

Now describe the properties of the compound you picked(gold). Compare the properties of the compound with the properties of the elements that comprise it. How do you explain the difference?

Answers

Explanation:

Gold conducts heat and electricity. ...

Gold is ductile: It can be drawn out into the thinnest wire. ...

Gold is highly reflective of heat and light. ...

Gold is prized for its beauty. ...

Gold is malleable, so it can be flattened into extremely thin sheets.

on the other hand Gold consist of copper

Key Properties of Copper Alloys

Excellent heat conductivity.

Excellent electrical conductivity.

Good corrosion resistance.

Good biofouling resistance.

Good machinability.

Retention of mechanical and electrical properties at cryogenic temperatures.

Non-magnetic.

so the difference is that copper is less expensive and not priced with its beauty

How do i calculate speed and find the direction of a moving object

Answers

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

The direction of a moving object is the direction the velocity vector points in. Where v1/2 is the magnitude of the velocity halfway to the top of the trajectory. So vdown=−vup - the two velocity vectors point in opposite directions not the same direction.

A sample of unknown gas has a temperature of 378k. When the temperature is increased to 546k,the volume also increases to 1047 ml. What was the original volume ?

Answers

Given :

A sample of unknown gas has a temperature of 378 K.

[tex]T_i = 378 \ K , \ T_f = 546 \ K[/tex]

When the temperature is increased to 546 K, the volume also increases to 1047 ml.

[tex]V_f - V_i = 1047 \ ml[/tex]

Solution :

We know, temperature is directly proportional to volume.

[tex]\dfrac{T_i}{T_f}=\dfrac{V_i}{V_f}\\\\\dfrac{T_i}{T_f} = \dfrac{V_i}{1047 + V_i}\\\\\dfrac{V_i}{1047+V_i}=\dfrac{378}{546}\\\\546V_i = 378V_i + 378\times 1047\\\\168V_i = 3,95,766\\\\V_i = 2,355.75\ ml[/tex]

Therefore, the original volume is 2.355.75 ml.

What is the balanced equation for these reactions?

I give Brainliest! Please no links

Answers

Answer:

SeCl₆ + O₂ → SeO₂ + 3Cl₂

Explanation:

Unbalanced:

SeCl₆ + O₂ → SeO₂ + Cl₂

Count the atoms.

On the left side, we have 1 Se atom, 6 Cl atoms, and 2 O atoms.

On the right side, we have 1 Se atom, 2 O atoms, and 2 Cl atoms.

So everything is balanced except for Cl. To balance, we put a 3 coefficient in front of Cl₂.

SeCl₆ + O₂ → SeO₂ + 3Cl₂

how many moles of ammonia could be obtained from a maximum of 5.0 moles of nitrogen​

Answers

Answer:

10 moles of ammonia could be obtained from a maximum of 5.0 moles of nitrogen​.

Explanation:

The balanced reaction is:

N₂ + 3 H₂ → 2 NH₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

N₂: 1 moleH₂: 3 molesNH₃: 2 moles

Then you can apply the following rule of three: if by reaction stoichiometry 1 mole of nitrogen produces 2 moles of ammonia, 5 moles of nitrogen produces how many moles of ammonia?

[tex]moles of ammonia=\frac{5 moles of nitrogen*2 moles of ammonia}{1 mole of nitrogen}[/tex]

moles of ammonia= 10

10 moles of ammonia could be obtained from a maximum of 5.0 moles of nitrogen​.

An atom of a certain element has 19 protons, 19 electrons, and a mass number of 39. This element is very reactive. How many neutrons are in this atom?

Answers

Answer:

There would be [tex]20[/tex] neutrons in that atom.

Explanation:

The mass number of an atom is the sum of:

the number of neutrons in this atom, andthe number of protons in this atom.

Electrons do not contribute to the mass number of an atom.

From the question:

Mass number of this atom: [tex]39[/tex].Number of protons in this atom: [tex]19[/tex].

[tex](\text{Mass Number}) = (\text{Number of protons}) + (\text{Number of neutrons})[/tex].

In this atom:

[tex]39 = 19 + (\text{Number of neutrons})[/tex].

Hence, the number of neutrons would be [tex]39 - 19 = 20[/tex].

How many atoms are there in 8.80 moles magnesium chloride? (write your answer in scientific notation).

Answers

Answer:

There are 5.30*10²⁴ atoms in 8.80 moles magnesium chloride.

Explanation:

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 1 mole of magnesium chloride contains 6.023*10²³ atoms, 8.80 moles of magnesium chloride contain how many moles of atoms?

[tex]amount of atoms=\frac{8.80 moles* 6.023*10^{23} atoms }{1 mole}[/tex]

amount of atoms= 5.30*10²⁴

There are 5.30*10²⁴ atoms in 8.80 moles magnesium chloride.

A 10.150g sample of a compound known to contain phosphorus and oxygen yields 5.717 g of oxygen. Find the empirical formula of the compound

Answers

Answer: The empirical formula is [tex]P_2O_5[/tex]

Explanation:

Mass of O = 5.717 g

Mass of P= (10.150-5.717) g = 4.433 g  

Step 1 : convert given masses into moles.

Moles of O =[tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{5.717g}{16g/mole}=0.357moles[/tex]

Moles of P=[tex]\frac{\text{ given mass of P}}{\text{ molar mass of P}}= \frac{4.433g}{31g/mole}=0.143moles[/tex]  

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For O = [tex]\frac{0.357}{0.143}=2.5[/tex]  

For P =[tex]\frac{0.143}{0.143}=1[/tex]

The ratio is to be converted to whole number

Thus whole number ratio of O : P = [tex]2.5\times 2:1\times 2=5: 2[/tex]

Hence the empirical formula is [tex]P_2O_5[/tex]

The periodic table is an important but rather dry scientific tool. It lists all the chemical elements, ordered by their atomic numbers. Elements with similar behavior are grouped in the same column (called a group), with metals generally on the left and non-metals (gases) on the right. Rows are called “periods” - hence, periodic table.

Identify one factor represented in the diagram that is used to classify the ten types of clouds

Answers

Low clouds
Stratus clouds are uniform grayish clouds that often cover the sky. Usually no precipitation falls from stratus clouds, but they may drizzle. When a thick fog “lifts,” the resulting clouds are low stratus. Nimbostratus clouds form a dark gray, “wet” looking cloudy layer associated with continuously falling rain or snow. They often produce light to moderate precipitation.

Middle clouds
Clouds with the prefix “alto” are middle-level clouds that have bases at 6,500 to 23,000 feet up. Altocumulus clouds are made of water droplets and appear as gray, puffy masses, sometimes rolled out in parallel waves or bands. These clouds on a warm, humid summer morning often mean thunderstorms by late afternoon. Altostratus clouds, gray or blue-gray, are made up of ice crystals and water droplets. They usually cover the sky. In thinner areas of them, the sun may be dimly visible as a round disk. Altostratus clouds often form ahead of storms that produce continuous precipitation.

High clouds
Cirrus clouds are thin, wispy clouds blown by high winds into long streamers. They are considered “high clouds,” forming at more than 20,000 feet. They usually move across the sky from west to east and generally mean fair to pleasant weather. Cirrostratus, thin, sheetlike clouds that often cover the sky, are so thin the sun and moon can be seen through them. Cirrocumulus clouds appear as small, rounded white puffs. Small ripples in the cirrocumulus sometimes resemble the scales of a fish, creating what is sometimes called a “mackerel sky.”

Vertical clouds
Cumulus clouds are puffy and can look like floating cotton. The base of each is often flat and may be only 330 feet above ground. The top has rounded towers. When the top resembles a cauliflower head, it is called “cumulus congestus.” These grow upward and if they continue to grow vertically can develop into a giant cumulonimbus, a thunderstorm cloud, with dark bases no more than 1,000 feet above ground and extending to more than 39,000 feet. Tremendous energy is released by condensation of water vapor in a cumulonimbus. Lightning, thunder and violent tornadoes are associated with them.
