If the pressure in a cylinder is 1 atm and the volume is 0.725 liters, then
what is the pressure when the volume is decreased to .075 liters (at
constant temperature)? *
2.5 atm
5 atm
5 atm
9.7 atm
O
13.2 atm

Answers

Answer:

9.7 atm.

Explanation:

The following data were obtained from the question:

Initial pressure (P1) = 1 atm

Initial volume (V1) = 0.725 L

Final volume (V2) = 0.075 L

Final pressure (P2) =?

The final pressure can be obtained by using the Boyle's law equation since the temperature is constant. This is illustrated below:

P1V1 = P2V2

1 x 0.725 = P2 x 0.075

Divide both side by 0.075

P2 = 0.725 / 0.075

P2 = 9.7 atm.

Therefore, the new pressure is 9.7 atm.

If the following weights have masses of 2, 4, 6 and 8 kg,
respectively, and they are at the same temperature, which one
will transfer more heat if they are all placed in cold water to
cool down? Explain.

Unit is calorimetry

Answers

Answer:

8 kg mass

Explanation:

As we can see in the image the weight of mass 8 kgs has a large surface area as compared to the surface area of other masses. In general, it has been observed that a wide surface area has more surface particle for heat conduction. Hence, the rate of heat transfer is directly proportional to the surface area of heat conducting surface. Thus, the larger the surface area, the faster is the rate of heat conduction.

Hence, weight of mass 8Kg wil transfer heat a fast rate.

How many milliliters of 0.2 M NaOH are required to exactly neutralize 40 milliliters of 0.1 M HCl?

A) 10
B) 20
C) 40
D) 80

Answers

Answer:

Option B. 20mL

Explanation:

Step 1:

Data obtained from the question.

Volume of base (Vb) =..?

Molarity of base (Mb) = 0.2M

Volume of acid (Va) = 40mL

Molarity of acid (Ma) = 0.1M

Step 2:

The balanced equation for the reaction.

HCl + NaOH —> NaCl + H2O

From the balanced equation above, the following were obtained:

Mole ratio of the acid (nA) = 1

Mole ratio of the base (nB) = 1

Step 3:

Determination of the volume of base, NaOH needed for the reaction. This is illustrated below:

MaVa/MbVb = nA/nB

0.1 x 40 / 0.2 x Vb = 1

Cross multiply

0.2 x Vb = 0.1 x 40

Divide both side by 0.2

Vb = 0.1 x 40 / 0.2

Vb = 20mL

Therefore, the volume of the base is 20mL.

Explain in your own words, why can’t we predict earthquakes?

Answers

There is currently no way to reliably predict when an earthquake will happen, its strength or length. Earthquakes can vary in their magnitude, the size of the earthquake at its source, and length, lasting from seconds to minutes.

Research has shown, that shaking of an earthquake displays a characteristic pattern. After the first tremors start, building up in intensity, a peak is reached, followed by a fading shaking. Large and small earthquakes start the same way, but there is no way to say when the peak, the maximal magnitude of the quake, is reached.

A 0.223 mole sample of gas is held at 33.0 C and 2.00 atm, What's the volume of the gas? R = 0.0821 L atm / mol K answer soon il give brainiest.

Answers

Answer:

The volume of the gas is 2.80 L.

Explanation:

An ideal gas is a theoretical gas that is considered to be made up of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The Pressure (P) of a gas on the walls of the container that contains it, the Volume (V) it occupies, the Temperature (T) at which it is located and the amount of substance it contains (number of moles, n) are related from the equation known as Equation of State of Ideal Gases:

P*V = n*R*T

where R is the constant of ideal gases.

In this case:

P= 2 atmV= ?n=0.223 molesR= 0.0821 [tex]\frac{L*atm}{mol*K}[/tex]T=33 °C= 306 °K (being O°C= 273°K)

Replacing:

2 atm* V= 0.223 moles*0.0821 [tex]\frac{L*atm}{mol*K}[/tex]* 306 K

Solving:

[tex]V=\frac{0.223 moles*0.0821\frac{L*atm}{mol*K} * 306 K}{2 atm} \\[/tex]

V= 2.80 L

The volume of the gas is 2.80 L.

For the following reaction, if you have 13.2 g of CO and 42.7g of Fe2O3, which is the limiting reagent with regards to Fe production?

Fe2O3 (s) + 3 CO (g) _______> 2 Fe (s) + 3 CO2 (g)

Answers

Answer: [tex]CO[/tex] is the limiting reagent and [tex]Fe_2O_3[/tex] is the excess reagent.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} Fe_2O_3=\frac{42.7g}{159.69g/mol}=0.267moles[/tex]

[tex]\text{Moles of} CO=\frac{13.2g}{28g/mol}=0.471moles[/tex]

The given balanced equation is :

[tex]Fe_2O_3(s)+3CO(g)\rightarrow 2Fe(s)+3CO_2(g)[/tex]

According to stoichiometry :

3 moles of [tex]CO[/tex] require = 1 mole of [tex]Fe_2O_3[/tex]

Thus 0.471 moles of [tex]CO[/tex] will require=[tex]\frac{1}{3}\times 0.471=0.157moles[/tex]  of [tex]Fe_2O_3[/tex]

As given amount of [tex]Fe_2O_3[/tex] is more than the required amount , it is the excess reagent.Thus [tex]CO[/tex] is the limiting reagent as it limits the formation of product.

For the reaction: 2 H3PO4 + 3 Ca(OH)2 → Ca3(PO4)2 + 6 H2O If you have 59.8 mL of 1.60 M phosphoric acid, how many mL of 0.500 M calcium hydroxide do you need to neutralize the acid?

Answers

Answer:

V = 127.57 mL

Explanation:

In this case, we are having an acid base titration, and this, according to the overall reaction:

2H₃PO₄ + 3Ca(OH)₂ -----> Ca₃(PO₄)₂ + 6H₂O

This reaction was neutralized, so, it's a neutralization reaction, therefore, we can use the following expression for neutralization reactions:

n₁ = n₂  (1)

This is because, in the equivalence point, both moles of the reagents are the same. Now we need to do a relation between this and the actual moles that we have according to the overall reaction.

In this case, we have 2 moles of acid reacting with 3 moles of base, so, the equation (1) is re-written like this:

2n₁ = 3n₂   (2)

Knowing this, and that we have values of concentrations and volume, we can write the expression of moles in terms of molarity and volume:

n = M * V    replacing in (2):

2M₁V₁ = 3M₂V₂   From here, we can solve for V₂ which is the volume of the base:

V₂ = 2M₁V₁ / 3M₂   (3)

Now, all we have to do is replace the given values to obtain the volume of the base:

V₂ = 2 * 1.6 * 59.8 / 3 * 0.5

V₂ = 127.57 mL

Answer:

[tex]V_{Ca(OH)_2}=0.287L=287mL[/tex]

Explanation:

Hello,

In this case, given the reaction:

[tex]2 H_3PO_4 + 3 Ca(OH)_2 \rightarrow Ca_3(PO_4)_2 + 6 H_2O[/tex]

We first compute the moles of phosphoric acid that are actually reacting given the volume (must be in litres) and the molarity:

[tex]n_{H_3PO_4 }=1.60\frac{mol}{L}*59.8mL*\frac{1L}{1000mL} =0.0957molH_3PO_4[/tex]

Next, we compute the moles of calcium hydroxide that are reacting by using the 3:2 molar ratio with phosphoric acid:

[tex]n_{Ca(OH)_2}=0.0957molH_3PO_4*\frac{3molCa(OH)_2}{2molH_3PO_4} =0.144molCa(OH)_2[/tex]

Finally, by knowing the 0.500 M of the calcium hydroxide solution we compute the required volume:

[tex]V_{Ca(OH)_2}=\frac{n_{Ca(OH)_2}}{M_{Ca(OH)_2}}=\frac{0.144mol}{0.500\frac{mol}{L} } \\ \\V_{Ca(OH)_2}=0.287L=287mL[/tex]

The pressure of a gas in a cylinder when it is heated to a temperature of 250k is 1.5 atm. What was the initial temperature of the gas if it’s initial pressure was 1 atm?

Answers

Answer:

[tex]T1=166.66K[/tex]

Explanation:

According to Gay-Lussac’s law simply states that the ratio of the initial pressure and temperature is equal to the ratio of the final pressure and temperature for a gas of a fixed provided that the mass is kept at a constant volume.

Given:

Initial pressure, P1 = 1 atm

Final pressure, P2 = 1.5 atm

Final temperature, T2 = 250 K

The law can be applied using the below formula

P1T2 = P2T1

Then,

T1 = (P1T2)/P1 = (1*250)/(1.5) = 166.66 Kelvin.

[tex]T1=166.66K[/tex]

:

Answer:

[tex]T_1=166.7K[/tex]

Explanation:

Hello,

In this case, by applying the Gay-Lussac's law which help us to understand the pressure-temperature gas behavior via a directly proportional relationship:

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]

In such a way, as we are asked to compute the initial temperature knowing the initial pressure and final both temperature and pressure, so we solve for it:

[tex]T_1=\frac{T_2P_1}{P_2}=\frac{250K*1atm}{1.5atm} \\\\T_1=166.7K[/tex]

Using the equation below, calculate the approximate moles of oxygen gas (O2) required to completely react with 719.68 moles of aluminum (Al). 4Al (s) + 3O2(g) -----> 2Al2O3(s)

Answers

Answer:

539.76 moles of O₂

Explanation:

Equation of reaction:

4Al + 3O₂ → 2Al₂O₃

From the equation of reaction above, 4 moles of Al will react with 3 moles of O₂

We can use mole-concept to find the number of moles of O₂.

4 moles of Al = 3moles of O₂

719.68 moles of Al = x moles of O₂

X = (3 × 719.68) / 4

X = 2159.04 / 4

X = 539.76 moles

539.76 moles of O₂ will react with 719.68 moles of Al

Answers

Answer:

a) 29.0 years

b) 0.89 g

Explanation:

Using the formula

t1/2= t×ln2/ln(No/Nt)

Where

Nt= mass of radioactive isotope at time= t =0.953g

No= initial mass of radioactive isotope present= 1.000g

t= time taken for N mass of radioactive isotope to remain = 2 years

t1/2 = half-life of radioactive isotope= ???

Substituting the values

t1/2= 2 × ln2/ln(1.000/0.953)

t1/2= 2× 0.693/0.048

t1/2= 29 hours

b)

N= No(1/2)^t/t1/2

Where t= 5 years

N= 1.000(1/2)^5/29

N= 1.000(1/2)^0.17

N= 0.89g
