Answer:

Explanation:

Work is a net force applied through a distance in order to displace an object, commonly abbreviated as W. A net force is the sum of all forces acting on an object. Work is mass times acceleration and distance so to find out the work you simply calculate the acceleration of the box being brought in. Next find the distance it was carried to get in the house. Then find out the mass of the box and finally multiply those sums together to get the amount of work put in to bring the package inside.

have a nice day

Answer:

Your answer will be..

John will travel to Russia next week.

Explanation:

He will travel NEXT week so we need to say that he will travel next week.

This may help:

Past tense:  We use -ed because that shows the we already did or finished it. EX: We traveled to Russia over the Spring break

Current Tense:  You will use -ing to show that you are traveling in the current time. EX:We are traveling to Russia.

Future tense:  You might use -ing or keep it the root word. EX: We will be traveling to Russia next week.

We will travel next week.

Answer:

[tex]T_2=339K[/tex]

Explanation:

Hello there!

In this case, according to the Charles' gas law as way to understand the volume-temperature as a directly proportional relationship for this problem, we can write:

[tex]\frac{T_2}{V_2}=\frac{T_1}{V_1}[/tex]

Thus, given the initial temperature and volume and the final volume, we are able to calculate the final temperature as follows:

[tex]T_2=\frac{T_1V_2}{V_1} \\\\T_2=\frac{252K*5.25L}{3.90L}\\\\T_2=339K[/tex]

Best regards!

Answer:

119.98 mL

Explanation:

Initial volume V1 = 123 ml

Initial temperature = T1 = 21◦C + 273 = 294 K

Initial pressure P1 = 760 Torr - 18.65 Torr = 741.35 Torr

Final volume V2= ???

Final temperature = T2= 21◦C + 273 = 294 K

Final pressure P2 = 760 Torr

From;

P1V1/T1= P2V2/T2

P1V1T2 = P2V2T1

V2 = P1V1T2/P2T1

V2= 741.35 * 123 * 294/760 * 294

V2 = 119.98 mL

Answer:

2.114 atm

Explanation:

Since it is just pressure and volume, use Boyle's Law

P1V1 = P2V2

Then plug in numbers

(1 atm)(1 L) = P2(.473 L)

P2 = 2.114 atm

Answer:

[tex]\boxed {\boxed {\sf 104 \%}}[/tex]

Explanation:

Percent ratio is the ratio of the actual yield to the theoretical yield. The formula is below.

[tex]Percent \ Yield} = \frac{{Actual \ Yield}}{{Theoretical \ Yield}} \times 100 \%[/tex]

The reaction of sodium and chlorine should theoretically yield 12.5 grams, but the actual yield was 13.0 grams.

Substitute these values into the formula.

[tex]Percent \ Yield} = \frac{{13.0 \ g }}{{12.5 \ g}} \times 100 \%[/tex]

Divide.

[tex]Percent \ Yield} = 1.04 \times 100 \%[/tex]

Multiply.

[tex]Percent \ Yield= 104 \%[/tex]

For this reaction, the percent yield is 104%

Answer:

54.4g

Explanation:

Let's first take account of what we have and what we're looking for.

Q = heat energy (Joules, J)= 490 J

m = mass of a substance= ??

c = specific heat (units J/kg∙K)= 0.50 J/g°C

∆T = change in temperature (Kelvins, K)= Final temperature - initial temperature -> (0C - (-18C))

We can use Q = mc∆T to determine the mass, we'll rearrange the formula to solve for mass, so it'll be: m=Q/c∆T. Let's plug it all in.

m= 490J / (0.50 J/g°C x ((0C - (-18C)))

m= 490J / (0.50 J/g°C x (0 + 18))

m=  490J / (0.50 J/g°C x 18)

m= 490J / 9 J/g

m= 54.4g of glass

Answer:

-217 kJ

Explanation:

ΔH =  reactant energy - product energy

ΔH = [(C-H) × 2 + (C≡C)] + [2 × H-I] - [(I-C) × 2 + (C-H) × 4 + (C-C)]

ΔH = [ (413 × 2 ) + 839 + 2(299)]  - [(240 × 2) + (413 × 4) + 348]

ΔH = [826 +839 + 598] -  [ 480 +1652 + 348]

∴ ΔH = -217

Answer:

1514g of CO₂ reacted

Explanation:

Based on the reaction:

2CO₂ + 43.9kJ → 2CO + O₂

2 moles of carbon dioxide require 43.9kJ of energy to produce 2 moles of carbon monoxide and 1 mole of oxygen

To solve this question, we must convert the 755kJ of energy to moles of carbon dioxide that reacts and to find the mass as follows:

755kJ * (2 moles CO₂ / 43.9kJ)  =34.4 moles of CO₂ are produced

Mass CO₂: Molar mass: 44.01g/mol

34.4 moles CO₂ * (44.01g / mol) =

Answer:

1.44 g

Explanation:

The problem gives you the molarity and volume of the target solution, so right from the start you know that you can use that information to determine the number of moles of hydrochloric acid that it must contain.

Answer:

"Electron binding energy, more commonly known as ionization energy, is a measure of the energy required to free an electron from its atomic orbital or from a solid. ... The atomic binding energy of the atom is the energy required to disassemble an atom into free electrons and a nucleus."

Explanation:

Hope this helps! <33

God bless your heart <3333

have a wonderful day!

Binding energy is a required amount of energy that disperses the other particles of the reaction system. It measures the energy needed to free an electron or a subatomic particle.

Binding energy is the ionization energy that depicts how much energy will be needed if an electron has to be removed from an atom for a reaction to occur.

It can be said that the energy required to free an electron from the orbit of the atom is measured in electron volt (eV). It is a little different from ionization energy as binding energy can remove any subatomic particle and not just an electron.

Therefore, the binding energy measures the freed subatomic particle.

Answer:

0.092M

Explanation:

Molarity of glucose solution = number of moles ÷ volume

According to this question, 12.5g of glucose (C6H12O6) is dissolved in enough water to make 750mL of solution.

Molar mass of glucose (C6H12O6) = 12(6) + 1(12) + 16(6)

= 72 + 12 + 96

= 180g/mol

mole = mass/molar mass

mole = 12.5/180

mole = 0.069mol

Volume of solution = 750mL = 750/1000 = 0.750L

Hence, molarity = n/V

Molarity = 0.069 ÷ 0.750

Molarity = 0.092M

Answer:

5.83 M

Explanation:

3.5 M * 125.0 ml  =  M₂ * 75.0ml

M₂ = 437.5 M.ml / 75.0 ml

M₂ = 5.83 M

Answer: The final temperature of the system will be [tex]13.14^0C[/tex]

Explanation:

[tex]heat_{absorbed}=heat_{released}[/tex]

As we know that,  

[tex]Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})[/tex]

[tex]m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)][/tex]         .................(1)

where,

q = heat absorbed or released

[tex]m_1[/tex] = mass of steam = 25 g

[tex]m_2[/tex] = mass of water = 0.2384 kg = 238.4 g   (1kg=1000g)

[tex]T_{final}[/tex] = final temperature = ?

[tex]T_1[/tex] = temperature of steam = [tex]116^oC[/tex]

[tex]T_2[/tex] = temperature of water = [tex]8^oC[/tex]

[tex]c_1[/tex] = specific heat of steam = [tex]1.996J/g^0C[/tex]

[tex]c_2[/tex] = specific heat of water= [tex]4.184J/g^0C[/tex]

Now put all the given values in equation (1), we get

[tex]25g\times 1.996J/g^0C\times (T_{final}-116)=-[238.4g\times 4.184J/g^0C\times (T_{final}-8)][/tex]

[tex]T_{final}=13.14^0C[/tex]

Therefore, the final temperature of the system will be [tex]13.14^0C[/tex]

E) +355 kJ

Explanation:

Based on Hess's law, it is possible to obtain ΔH of a reaction from the sum of similar reactions:

(1) IF(g) + F2(g) → IF3(g) ΔH = -390kJ

(2) IF(g) + 2F2(g) → IF5(g) ΔH = -745kJ

The sum of (1) - (2) is:

IF(g) + F2(g) → IF3(g)

IF5(g) → IF(g) + 2F2(g)

_________________

IF5(g) → IF3(g) + F2(g)

ΔH = -390kJ - (-745kJ)

ΔH = +355kJ

The correct answer is "[tex]1.21\times 10^5 \ Pa[/tex]".

Explanation:

The given values are:

Number of moles,

n = 2.5 moles

Volume,

V = 45 liters

Temperature,

T = 261 K

As we know,

⇒  [tex]PV=nRT[/tex]

or,

⇒  [tex]P=\frac{nRT}{V}[/tex]

On substituting the values, we get

⇒      [tex]=\frac{2.5\times 0.0821\times 261}{45}[/tex]

⇒      [tex]=\frac{53.57}{45}[/tex]

⇒      [tex]=1.19 \ atm[/tex]

On converting it in Pa, we get

⇒      [tex]=1.21\times 10^5 \ Pa[/tex]

Answer:

Endothermic

Explanation:

An endothermic reaction is one in which energy is absorbed while an exothermic reaction is one in which energy is given out(evolved).

If we look at the reaction as written; 3C(graphite) + 3H2(g) + 88kcal -------> C3H8(g), we will notice that;

i) 88kcal of energy had to be absorbed for the reaction to occur

ii) The enthalpy change for the reaction is positive.

Since energy must be taken in to drive the forward reaction, then the reaction is endothermic as written.
