In if the reaction below 49 grams of Fe3O4 produces a 78.25% yield of Fe. How many grams are produced? Fe3O4 + 4H2 = 3Fe + 4H2O
Imagine the = is an arrow

Answers

Answer 1

Fe produced : 27.53 g

Further explanation

Reaction

Fe₃O₄ + 4H₂ = 3Fe + 4H₂O

mol Fe₃O₄ (MW=233.55 g/mol) :

[tex]\tt \dfrac{49}{233.55 g/mol}=0.21[/tex]

mol ratio Fe₃O₄ : Fe = 1 : 3, so mol Fe :

[tex]\tt 3\times 0.21=0.63~g/mol[/tex]

mass Fe(Ar=55,845 g/mol)

[tex]\tt 0.63\times 55,845=35.18~g[/tex]

grams produced :

[tex]\tt \%yield=\dfrac{actual}{theoretical}\times 100\%\\\\actual=\%yield\times theoretical\\\\actual=78.25\%\times 35.18\\\\actual=27.53~g[/tex]

Explanation:

How many molecules of nitrogen dioxide gas (NO2) are present in 15 liters of the gas at STP?

Answers

Answer:

4.031×[tex]10^{23}[/tex]

Explanation:

You first need to calculate the number moles of NO2.  To do this use PV=nRT

STP stands for standard temperature and pressure which is 0 degrees C and 1 atm.

due to that:

P = 1 atm

V = 15 L

R = 0.08206 L*atm/mol*K

T = 273 K

n = unknown moles

solve for n to make the equation n=PV/RT

n=(1atm*15L)/(0.08206 Latm/molK*273K)

n=0.6696 mol of NO2

Then to find the number of molecules we use Avogadro's number which tells us the number of molecules per mol of a molecule or atom.

Avogadro's number is  6.02x10^23 molecules/mol

number of molecules = 0.6696mol × 6.02x10^23 molecules/mol

number of molecules = 4.031×10^23 molecules of NO2

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³.

What is element?

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

The systematic distribution of electrons in the various atomic orbitals is called its electronic configuration. The atomic number of vanadium is 23. The electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³. The noble gas electronic configuration of vanadium is  [Ar]3d³4s². 1,2,3 represents the number of shells and s and represents the orbitals. The superscripts represents the number of electrons in each orbitals.

What is the formula for Iron (III) Bromate

Answers

Answer:

[tex]\boxed {\boxed {\sf FeBr_3}}[/tex]

Explanation:

We can assume that this is a neutral compound, meaning the charges of the ions are balanced.

We are given: Iron (III) Bromide.

We want to find the chemical formula.

First, find the symbols of the elements.

Fe: Iron Br: Bromine

Next, find the charges on the ions.

The Roman Numeral 3 in parentheses (III). This indicates the iron cation has a charge of +3.

We need to balance out the charge of +3 with the bromine. Bromine can have a charge of +5, +1, and -1. Since we already have a cation (positive ion), bromine must be an anion (negative ion). We also know the charge must be negative to balance out the compound.

But, the charge is only -1. That would still leave the compound unbalanced. Therefore, we must have 3 bromine atoms to balance out the iron. The 3 will become a subscript.

So, put all the information together and write the formula:

FeBr₃

A chemical formula lists the constituent elements of a compound together with the number of atoms in each element's smallest unit, such as a molecule or formula unit. Here the formula for Iron (III) Bromate is FeBr₃.

A compound's chemical composition is symbolically represented by its chemical formula. Chemical formulas reveal the elements that make up a compound's molecules as well as the ratio in which their atoms combine to create those molecules.

The sorts of atoms and their numbers in an element or compound are described by a chemical formula. Each element's atoms are denoted by one or two distinct letters. a collection of chemical symbols indicating the constituent elements and their corresponding ratios.

25.0cm3 of s saturated potassium hydroxide is neutralized by 35.0cm3 of hydrogen chloride acid of concentration 0.75 mol/dm3. Calculate the concentration of potassium hydroxide solution. Please help, will give brainliest, unhelpful answers will get reported.​

Answers

Answer:

Concentration of the original [tex]\rm KOH[/tex] solution: approximately [tex]1.05\; \rm mol \cdot dm^{-3}[/tex].

Explanation:

Notice that the concentration of the [tex]\rm HCl[/tex] solution is in the unit [tex]\rm mol\cdot dm^{-3}[/tex]. However, the unit of the two volumes is [tex]\rm cm^{3}[/tex]. Convert the unit of the two volumes to [tex]\rm dm^{3}[/tex] to match the unit of concentration.

[tex]\begin{aligned} V(\mathrm{NaOH}) &= 25.0\; \rm cm^{3} \\ &= 25.0\; \rm cm^{3} \times \frac{1\; \rm dm^{3}}{1000\; \rm cm^{3}} \approx 0.0250\; \rm dm^{3} \end{aligned}[/tex].

[tex]\begin{aligned} V(\mathrm{HCl}) &= 35.0\; \rm cm^{3} \\ &= 35.0\; \rm cm^{3} \times \frac{1\; \rm dm^{3}}{1000\; \rm cm^{3}} \approx 0.0350\; \rm dm^{3} \end{aligned}[/tex].

Calculate the number of moles of [tex]\rm HCl[/tex] molecules in that [tex]0.0350\; \rm dm^{3}[/tex] of [tex]0.75\; \rm mol \cdot dm^{3}[/tex] [tex]\rm HCl\![/tex] solution:

[tex]\begin{aligned}n(\mathrm{HCl}) &= c(\mathrm{HCl}) \cdot V(\mathrm{HCl}) \\ &= 0.00350\; \rm dm^{3} \times 0.75\; \rm mol \cdot dm^{3} \\ &\approx 0.02625\; \rm mol\end{aligned}[/tex].

[tex]\rm HCl[/tex] is a monoprotic acid. In other words, each [tex]\rm HCl\![/tex] would release up to one proton [tex]\rm H^{+}[/tex].

On the other hand, [tex]\rm KOH[/tex] is a monoprotic base. Each [tex]\rm KOH\![/tex] formula unit would react with up to one [tex]\rm H^{+}[/tex].

Hence, [tex]\rm HCl[/tex] molecules and [tex]\rm KOH\![/tex] formula units would react at a one-to-one ratio.

[tex]{\rm HCl}\, (aq) + {\rm NaOH}\, (aq) \to {\rm NaCl}\, (aq) + {\rm H_2O}\, (l)[/tex].

Therefore, that [tex]0.02625\; \rm mol[/tex] of [tex]\rm HCl[/tex] molecules would neutralize exactly the same number of [tex]\rm NaOH[/tex] formula units. That is: [tex]n(\mathrm{NaOH}) = 0.02625\; \rm mol[/tex].

Calculate the concentration of a [tex]\rm NaOH[/tex] solution where [tex]V(\mathrm{NaOH}) = 0.0250\; \rm dm^{3}[/tex] and [tex]n(\mathrm{NaOH}) = 0.02625\; \rm mol[/tex]:

[tex]\begin{aligned}c(\mathrm{NaOH}) &= \frac{n(\mathrm{NaOH})}{V(\mathrm{NaOH})} \\ &= \frac{0.02625\; \rm mol}{0.0250\; \rm dm^{3}}\approx 1.05\; \rm mol \cdot dm^{-3}\end{aligned}[/tex].

Answers

Answer:

B.

Explanation:

Velocity: the speed of something given direction

Acceleration: increase or decrease of velocity over time

B is the answer because it is the only point on the image that has to slow down and change direction. To turn, a vehicle must slow down so it doesn't skid. Hope this helps!

A race car traveling around the racetrack at a constant speed of 150km/hr at B point on the track is the car accelerating.

What is acceleration ?

Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities, accelerations. The direction of the net force applied on the item determines the object's acceleration.

An item has positive acceleration if it is accelerating and travelling in the right direction. Positive acceleration was demonstrated in the first case by the fast automobile.

The acceleration is in the same direction as the car's motion since it is moving ahead and speeding up.

The equation a = v/t denotes acceleration ( a ), which is the change in velocity ( v ) over the change in time ( t ). This enables you to calculate the change in velocity in meters per second squared  ( m/s² ).
