Answer: The correct answer is 5.00 moles

Explanation:

Answer:

a) 5.6 L

Explanation:

Step 1: Given data

Atoms of helium: 1.5 × 10²³ atoms

Conditions: Standard temperature (273.15 K) and pressure (1 atm)

Step 2: Calculate the moles corresponding to 1.5 × 10²³ atoms

To convert atoms to moles, we will use Avogadro's number: there are 6.02 × 10²³ atoms of helium in 1 mole of atoms of helium.

1.5 × 10²³ atoms × 1 mol/6.02 × 10²³ atoms = 0.25 mol

Step 3: Calculate the volume of 0.25 moles of He at STP

At STP, 1 mole of helium occupies 22.4 L.

0.25 mol × 22.4 L/1 mol = 5.6 L

Explanation:

Answer: trigonal bipyramidal

Explanation:

Number of electron pairs = [tex]\frac{1}{2}[V+N-C+A][/tex]

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

[tex]SbCl_5[/tex] :

In the given molecule, antimony is the central atom and there are five chlorine as monovalent atoms.

The number of electron pairs are 5 that means the hybridization will be [tex]sp^3d[/tex] and geometry of the molecule will be trigonal bipyramidal.

Answer:

[tex]\boxed {\boxed {\sf +4}}[/tex]

Explanation:

Lead (Pb) has 2 positive oxidation states, +4 and +2.

Sulfur (S) has 3 oxidation states: +6, +4, and -2. Since lead creates a positive ion, sulfur must be a negative ion to balance the charges.

There are 2 atoms of sulfur, each with a charge of -2. Therefore, their overall charge is -4, because 2* -2= -4.

A compound has a net charge of 0. To achieve this, lead must have a charge of +4 to balance out the -4 charge of sulfur.

Lead has a +4 ionic charge in PbS₂

Explanation: molality = concentration = 0.400 mol/3.0 l

Answer:

I'm going to go with conduction

Explanation:

At first I thought it was combustion but I read the problem incorrectly. It seems like the liquid boils after you put them on the hot plate.

It's most likely conduction because heat and energy is being transferred into the liquid from the hot plate

Answer:

Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

Answer:

25.155 gram

Explanation:

HCl(aq.) + NaOH(aq.) ⇒ NaCl + H2O

According the above equation equal number of moles of reactant are producing same number of moles of products.

Now, no. mole of HCl = 15.7/(1+35.5) = 0.43 moles

no. of moles of NaOH = 27/(23+16+1) = 0.675 moles

Since  the  amount  of  sodium  hydroxide  exceeds  the  amount  of  hydrochloric  acid,  the maximum amount of each substance participating in the reaction is HClν ν  0.43 moles .Therefore, the maximum amount of NaCl  that can be produced is as follow

= (23+35.5)×0.43 = 25.155 gram

Answer:

116 g

Explanation:

From the question given above, the following data were obtained:

Number of mole of calcium = 2.9 moles

Mass of calcium =.?

The mole and mass of a substance are related according to the following formula:

Mole = mass / molar mass

With the above formula, we can obtain the mass of calcium. This can be obtained as follow:

Number of mole of calcium = 2.9 moles

Molar mass of calcium = 40 g/mol

Mass of calcium =.?

Mole = mass / molar mass

2.9 = mass of calcium / 40

Cross multiply

Mass of calcium = 2.9 × 40

Mass of calcium = 116 g

Therefore, the mass of 2.9 moles of calcium is 116 g.

I guess it WATER

Answer:

Sucrose contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose isomerizing to aldehyde, or the fructose to α-hydroxy-ketone form. Sucrose is thus a non-reducing sugar, which does not react with Benedict's reagent.

Answer:

21.6 grams

Explanation:

First we convert 10 g of N₂ into moles, using its molar mass:

Then we convert 0.36 moles of N₂ into moles of NO, using the stoichiometric coefficients of the balanced reaction:

Finally we convert 0.72 NO moles into grams, using its molar mass:

Explanation:

Sublimation describes a solid turning directly into a gas. Melting, on the other hand, occurs when a solid turns into a liquid. Water can, under the right circumstances, sublimate, though it usually melts at temperatures above 0 degrees Celsius or 32 degrees Fahrenheit. Carbon dioxide (CO2), however, is very different. The conditions that determine whether CO2 melts or sublimates are both temperature and atmospheric pressure.

Answer:

the wind and the temperature of water both drive ocean currents

Cars rust because when metal comes into contact with water or some sort of water form, it will make the surface wet. If the metal is wet for too long, it will start to soak up the water, therefore making it rusty. The salt will also rust a car. It does this because the mix of carbon dioxide and oxygen in the salt will eat away at the car, making it rust faster. Hope this helps!
