A Gas Has The Volume Of 45mL At 25 C Is Heated To 50 C. What Is The New Volume Of The Gas? P1V1 = P2V2

Answers

Answer 1

Answer:

Option b (V1/T1 = V2/T2) is the right alternative or the new volume will be "0.048 L".

Explanation:

The given values are:

Temperature,

T₁ = 25°C

or,

   = 298.15 K

T₂ = 50°C

or,

    = 323.15 K

Volume,

V₁ = 45 mL

or,

    = 0.045 L

V₂ = ?

As we know,

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

Or,

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

On substituting the values, we get

⇒       [tex]=\frac{0.045\times 323.15}{298.15}[/tex]

⇒       [tex]=\frac{14.541}{298.15}[/tex]

⇒       [tex]=0.048 \ L[/tex]

Look at the picture below. What is the name of the copper salt?

Answers

Answer:

The reaction took place is-

Fe + CuSO4 → Fe(SO4) + Cu

the copper salt name is copper sulphate!

The statement describes the name of the copper salt is "copper sulphate."

What are salt?

A salt is an ionic substance that is created when a positively charged ion bonds with a negatively charged ion.

The reaction occurred in the context of the image.

Fe + CuSO4(aq) → FeSO4(aq) + Cu(s)

A single displacement reaction is the sort of reaction. In this reaction, the highly reactive metal iron oxidises and creates ferrous sulphate by replacing the copper in copper sulphate by giving up two electrons.

Hence the correct answer is copper sulphate.

Answers

Fluorine is more reactive than Chlorine because it has a higher electro negativity and chlorine has more electrons which causes it to repel reacting electrons with greater force.

Elements are more reactive as you go down the periodic table because ionization energy decreases down a group which means they can lose electrons more easily, making them more reactive.

The modern periodic table is arranged by atomic number rather than atomic mass, and many discoveries of new elements have been made that make a more complete table.

The vertical columns and horizontal rows in Mendeleev’s table are called groups and periods respectively. There are seven periods and eight groups. Elements with the same properties are in the same group and all elements were ordered by atomic mass.

Three drawbacks of Mendeleev’s table are: it’s arranged by atomic mass rather than atomic number. Isotopes violate Mendeleev’s periodic law. Mendeleev could not figure out where to place hydrogen.

Modern periodic table is arranged by atomic number, it has 7 periods and 18 groups, and is divided into 4 blocks (s-, p-, d-, and f-)

The Texas Hill Country ecosystem supports a variety of organisms. Animals such as owls, coyote, snakes and hawks compete for small animals for food. What might happen if the population of these predators became too large? The predators would share the prey population equally among all of the predator species. The predators would begin to eat plants rather than their usual prey. The predators would have more offspring of great size. The predators would consume the prey population faster than it could be replaced.

Answers

Answer:

The predators would consume the prey population faster than it could be replaced.

Explanation:

According to Oxford dictionary; an ecosystem is "a biological community of interacting organisms and their physical environment."

An ecosystem is a self supporting unit that is composed of living and non living parts. The ecosystem should be self sustaining.

In the particular case mentioned in this question, when the predator population becomes so large, they will steadily diminish the prey population faster it can be replaced thereby distorting the balance of the ecosystem.

How do you determine if an equation is balanced or unbalanced.

Answers

You have to look at the number of each element on each side and see if they are equal.
For example in the following equation:
N2 + H2 = NH3
If you compare the Nitrogen’s, you see that on the left side you have 2 and on the right you only have one, so you would need to balance this equation.
An example of when you don’t need to balance:
K + H2 -> KH2
In this example, you can see that there is only one potassium (k) on each side. Now, you compare the hydrogens. We can see that there are two hydrogens on both sides. Since both sides have the same of each element, we do not need to balance this equation.
IN SHORT, balance if there are different numbers of one or more elements on both sides. Don’t balance if there are the same amount of each element on both sides.

You are performing a reaction involving the collection of a gas at SATP. If 5.00 g of magnesium is added to 100.0 cm3 of 0.100 mol dm−3 HCl, determine the volume of hydrogen gas that will be collected at SATP.

Answers

Answer: The volume of hydrogen produced is 0.122 L

Explanation:

To calculate the moles :

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

[tex]\text{Moles of solute}={\text{Molarity}}\times {\text{Volume in L}}[/tex]  

[tex]\text{Moles of} Mg=\frac{5.00g}{24g/mol}=0.208moles[/tex]

[tex]\text{Moles of} HCl=[/tex][tex]0.100moldm^{-3}\times 0.1dm^3=0.01mol[/tex]

The balanced chemical equation is:

[tex]Mg+2HCl\rightarrow MgCl_2+H_2[/tex]  

According to stoichiometry :

2 moles of require = 1 mole of

Thus 0.01 moles of [tex]HCl[/tex] will require=[tex]\frac{1}{2}\times 0.01=0.005moles[/tex]  of [tex]Mg[/tex]

Thus is the limiting reagent as it limits the formation of product and is the excess reagent.

As 2 moles of give = 1 mole of

Thus 0.01 moles of [tex]HCl[/tex] give =[tex]\frac{1}{2}\times 0.01=0.005moles[/tex]  of [tex]H_2[/tex]

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1.0 atm  (SATP)

V = Volume of gas = ?  

n = number of moles = 0.005

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]25^0C=(25+273)K=298K[/tex] (SATP)

[tex]V=\frac{nRT}{P}[/tex]

[tex]V=\frac{0.005mol\times 0.0820 L atm/K mol\times 298K}{1.0atm}=0.122L[/tex]

Thus volume of hydrogen produced is 0.122 L

     W                       -7                                  60

     X                       660                              2500

     Z                         115                                445

Let's consider that:

Below the melting point, a substance is solid.Between the melting and the boiling point, a substance is liquid.Above the boiling point, a substance is gas.

(a) Which substance is a gas at 100°C?

At 100 °C, W is above the boiling point

(b) Which substance is a liquid for the largest range of temperature?

The largest difference between the melting point and the boiling point is that of X: 2500 - 660 = 1840.

(c) Which substance is liquid at 1000 °C and a gas at 2000°C?​

Y is between the melting and the boiling point at 1000 °C and above the boiling point at 2000 °C.

A gas confined in a 515cm3 container exerts a pressure of 107.4kPa at 38.6⁰C. At what Celsius temperature will it exert a pressure of 635.7kPa if it is placed into a 644cm3 container?

Answers

Answer: The temperature at pressure of 635.7 kPa is [tex]2033^0C[/tex]

Explanation:

The combined gas equation is,

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = initial pressure of gas = 107.4 kPa

[tex]P_2[/tex] = final pressure of gas = 635.7 kPa

[tex]V_1[/tex] = initial volume of gas = [tex]515cm^3[/tex]

[tex]V_2[/tex] = final volume of gas = [tex]644cm^3[/tex]

[tex]T_1[/tex] = initial temperature of gas = [tex]38.6^0C=(38.6+273)K=311.6K[/tex]

= final temperature of gas = ?

Now put all the given values in the above equation, we get:

[tex]\frac{107.4\times 515}{311.6}=\frac{635.7\times 644}{T_2}[/tex]

[tex]T_2=2306K=(2306-273)^0C=2033^0C[/tex]

The temperature at pressure of 635.7 kPa is  [tex]2033^0C[/tex]

Answers

Answer:

⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga

Explanation:

Nuclear reactions are reactions which occur with changes in the nucleus of an atom. Nuclear reactions usually occur with the release of large amounts of energy and radiation. Radiactive elements are elements that are involved in nuclearbreactions due to the unstable nature of their nucleus. They disintegrate spontaneously with the emission of radiations. The major types of radiations released during nuclear reactions are;

1, Alpha particles - these are positively charged radiations with strong ionizing power. Each alpha particle is a helium nucleus

2. Beta particles - these are very fast moving stream of electrons. They are negatively charged particles .

3. Gamma radiation - is a form of electromagnetic radiation.

In the alpha absorption of Cu-61, the proton number of the atom increases by 2 while the mass number increases by 4 and the Cu-61 atom is changed to Ga-65 atom. The nuclear equation is given as follows:
