If a 750 mL of a gas at a pressure of 100.7 kPa has a decrease of pressure to 99.8 kPa, what is the new volume? Show work

Answers

Answer 1

Explanation:

P1V1 = P2V2

(100.7 kPa)(0.75 L) = (99.8 kPa)V2

V2 = (100.7 kPa)(0.75 L)/(99.8 kPa)

= 0.757 L

Which is the balanced equation for a reaction between hydrogen gas and oxygen gas

Answers

Answer:

it is known that two molecules of hydrogen gas, H2, react with one molecule of oxygen gas, O2, to form two molecules of water, H2O. This reaction may be represented by the chemical equation 2H2+O2→2H2O. The formula weight of hydrogen gas is 2.01594, that of oxygen gas 31.9998, and that of water 18.01534

describe how to calculate the relative atomic mass

Answers

Hiii!
Here is your answer!!

You can always find the relative mass of an element by adding the number of protons to the number of neutrons for the specific isotope of the element you're considering. For example, a carbon-12 atom has 6 protons and 6 neutrons, and so has a relative atomic mass of 12.

Explanation:

A 1.85 kg textbook is sitting on a bookshelf 2.23 m above the floor. How much potential energy does it have?

Answers

Answer:

[tex]\boxed {\boxed {\sf 40.4299 \ Joules}}[/tex]

Explanation:

Potential energy is energy due to position. It is the product of mass, height, and acceleration due to gravity.

[tex]PE= m \times g \times h[/tex]

The mass of the textbook is 1.85 kilograms. Assuming this is on Earth, the acceleration due to gravity is 9.8 meters per square second. The height is 2.23 meters.

m= 1.85 kg g= 9.8 m/s²h= 2.23 m

Substitute the values into the formula.

[tex]PE = 1.85 \ kg \times 9.8 \ m/s^2 \times 2.23 \ m[/tex]

Multiply the first 2 numbers together.

[tex]PE=18.13 \ kg*m/s^2 *2.23 \ m[/tex]

Multiply again.

[tex]PE= 40.4299 \ kg*m^2/s^2[/tex]

1 kilogram square meter per square second (1 kg*m²/s²) is equal to 1 Joules (J) Our answer of 40.4299 kg*m²/s² is equal to 40.4299 J

[tex]PE= 40.4299 \ J[/tex]

The textbook has 40.4299 Joules of potential energy.

and a neutron
Uranium-235 absorbing a neutron and breaking into Barium-141,
Krypton-92 and three neutrons
0
None of the above
0

Answers

Answer:

Uranium-235 absorbing a neutron and breaking into Barium-141,  Krypton-92 and three neutrons

Explanation:

A fission reaction is said to have occurred when an unstable nucleus is bombarded with a neutron such that it disintegrates into daughter nuclei and produces more neutrons in the process. Hence, Uranium-235 absorbing a neutron and breaking into Barium-141,  Krypton-92 and three neutrons is a fission reaction.

This fission reaction is often a self sustaining reaction. The neutrons produced in the reaction bombards more of the parent nucleus and the process continues indefinitely(chain reaction).

Control rods and moderators are used to keep the chain reaction in check.

Answers

Answer:

Assertion (A) is true

but reason (R) is false.

Explanation:

If we look at the assertion closely, it is true that a sublime substance changes from solid to gas without  passing through a liquid state. Naphthalene, camphor, iodine and ammonium  chloride are some common  examples of the substances  which undergo sublimation.

However, not all solids first pass through a liquid state before converting to gas. Sublime solids such as those listed above passes directly from solid to gas without passing through a liquid state.

Hence the assertion is true but reason is false.

Consider an ideal gas contained in a cylinder with the volume 34.4L, temperature 667K and pressure 2atm.What will be pressure of the gas if it is heated at 1000k and the volume becomes 50L.

Answers

Given :

An ideal gas contained in a cylinder with the volume 34.4L, temperature 667K and pressure 2 atm.

To Find :

What will be pressure of the gas if it is heated at 1000k and the volume becomes 50L.

Solution :

We know, by ideal gas equation :

[tex]Pv = nRT[/tex]

Now, in the given question only their are two state and also their is no leakage so amount of gas is also constant.

So,

[tex]\dfrac{P_1V_1}{T_1} = \dfrac{P_2V_2}{T_2}\\\\\dfrac{2\times 34.4}{667} = \dfrac{P_2 \times 50}{1000}\\\\P_2 = \dfrac{2\times 34.4 \times 1000}{667 \times 50}\ atm\\\\P_2 = 2.06 \ atm[/tex]

Therefore, the pressure of gas is 2.06 atm.

B. the state with lowest possible energy


C. The same state in which it began

D. The state with the maximum disorder

Answers

Answer:

The state with the lowest possible energy consistent with the state of maximum disorder

so letter A

If a system is left to change spontaneously then, the state with the lowest possible energy is consistent with the state of maximum disorder. option A is correct.

what is spontaneous change?

A spontaneous change may be so fast or rapid or in a fraction of time that it is essentially instantaneous or fast or so slow that it cannot be observed over any practical time of  period.

A is the spontaneous change is one in which the system happening into which the  A an increase or boost  in internal energy B lowering  decline in entropy C lowering in energy D no energy change Medium.

The time-evolution  or change of a system in which it releases free energy and it moves to a lower, or decreased more thermodynamically stable energy state, closer to  attend the thermodynamic equilibrium.

Therefore, the system is left to change spontaneously then, and the state with the lowest possible energy is consistent with the state of maximum disorder. option A is correct.

B. Heat flows from block 2 to block 1

C. There is no heat flow

D. Heat flows back and forth from one block to another

Answers

Answer:

A. Heat flows from block 1 to block 2

Explanation:

Thermal or heat energy flows when objects of different temperature come in contact. Heat naturally flows from hot objects (high temperature) to cold objects (low temperature) and will keep on flowing until an equilibrium is reached.

According to this question, two blocks of metal, which are of different temperatures, are illustrated to be in contact. Block 1 is at 60°C while Block 2 is at 25°C. Block 1 is hotter than Block 2, hence, heat will flow from block 1 to block 2.

Answers

Answer:

a. absorbs energy as heat and has positive enthalpy of solution.

Explanation:

A reaction can either be exothermic or endothermic. An endothermic reaction, as the dissolution described in the question, is that which absorbs heat energy from the surroundings in order to start the reaction.

Because an endothermic reaction makes heat lost from the surroundings, the enthalpy (∆H) of the solution will be positive (+). ∆H is got by finding the difference between the enthalpy of the reactants and products and since the enthalpy of a product in endothermic reaction is more, the enthalpy change (∆T) will be positive.
