explain the effect of temperature, pressure, volume and concentration reaction rate

Answers

Answer 1

When you increase the pressure, the molecules have less space in which they can move. That greater density of molecules increases the number of collisions. When you decrease the pressure, molecules don't hit each other as often and the rate of reaction decreases. Pressure is also related to concentration and volume.

What factors are included on a phase diagram?
O A. Temperature and pressure
O B. Pressure and volume
O C. Mass and volume
O D. Heat and kinetic energy

Answers

Answer:

A. Temperature and pressure

Explanation:

The factors included in a phase diagram are the temperature and pressure conditions.

A phase diagram is a combined plot of three curves all in equilibrium;

Solid- liquid, liquid -gas, and solid -gas plots

On the vertical axis, we usually have the pressureOn the horizontal axis is where the temperature is represented. Most phase diagrams are used in chemistry and mineralogy to show areas in which different phases can exist at equilibrium.

The factors included on a phase diagram are temperature and pressure and the correct option is option A.

A phase diagram is a graphical representation that shows the different phases of a substance (solid, liquid, and gas) as a function of temperature and pressure. It provides valuable information about the conditions at which different phases can exist and the boundaries between them.

The temperature is typically plotted on the horizontal axis, while the pressure is plotted on the vertical axis.

By examining a phase diagram, one can determine the melting point, boiling point, and critical point of a substance, as well as the regions of stability for each phase. Additionally, phase diagrams can reveal the existence of phase transitions such as melting, boiling, and sublimation.

Thus, the ideal selection is option A.

identify the elements given the orbital diagrams listed below.​

Answers

Answer:

See explanation.

Explanation:

1. There are 8 electrons. Elements that end with 2p orbitals are in the 2nd period (aka row) of the periodic table. Elements that have 4 electrons in 2p are in the 16th group (aka column) (column 16 may also be referred to as 6A) of the periodic table. So looking at row 2, column 16, we can see that the first diagram is of O, Oxygen.

2. 8 electrons. This is the same diagram as the one above.

3. 13 electrons. Elements ending with 3p are in period 3. Elements with 1 valence electron in a p orbital are in group 13 (aka group 3A).

4. 7 electrons. We already know 2p is period 2. 3 valence electrons in a p orbital means that it is in group 15/group 5A.

I did not write the answers for #3 and 4 but they can be easily found on a periodic table with the info I gave.

The elements given the above orbital diagrams are as follows:

Oxygen

Oxygen

Aluminum

Nitrogen

In first case,

There are total 8 electron and the electronic configuration is 1s2 2s2 2p4. The element which end up with 2p configuration belongs to 2nd period. It have four electron in their outermost shell so, it belongs to 16th group, So the element is Oxygen.

In the same way we will find the elements for rest of the cases.

Thus, we reach to the conclusion that the elements given the above orbital diagrams are as follows:

Oxygen

Oxygen

Aluminum

With an average acceleration of 0.50 m/s?, how long will it take a cyclist starting from
rest to reach 13.5 m/s?

Answers

Answer:

t = 27 s

Explanation:

Given data:

Average acceleration = -0.50 m/s²

Time taken to reach to the 13.5 m/s = ?

Solution:

Formula:

Vf = V₀ + at

Vf = 0

V₀ = 13.5 m/s

a = -0.50 m/s²

Now we will put the values in formula.

0 = 13.5 m/s - 0.50 m/s²t

0.50 m/s²t =  13.5 m/s

t =  13.5 m/s / 0.50 m/s²

t = 27 s

What are different states of matter?

The matter is anything that has mass and occupies space.

Matter can exist in four different states: solid, liquid, gas, and plasma.

By examining the arrangement of molecules, it is possible to comprehend the characteristics of the many forms of matter.

The state of a solid turns to a liquid when it is heated past its melting point.

A liquid turns into a gas when it is heated past the point at which it vaporizes.

Solids have a distinct shape and dimension and are densely packed.

Liquids fill the container's space and are loosely packed.

Gas has a large intermolecular distance and is not stiff.

When energy is removed from the particles of a liquid, the speed gets slowed, and so the motion decreases, as the motion is limited they become packed and the distance between them decreases, and the intermolecular forces increases.

Explain what lattice energy is and how it affects the properties of ionic compounds. Describe the general properties of ionic compounds.

Answers

Answer:

The force of attraction between oppositely charged particles is directly proportional to the product of the charges on the two objects (q1 and q2) and inversely proportional to the square of the distance between the objects (r2).

The strength of the bond between the ions of opposite charge in an ionic compound therefore depends on the charges on the ions and the distance between the centers of the ions when they pack to form a crystal.

An estimate of the strength of the bonds in an ionic compound can be obtained by measuring the lattice energy of the compound, which is the energy given off when oppositely charged ions in the gas phase come together to form a solid.

Explanation:

The lattice energies of ionic compounds are relatively large. The lattice energy of NaCl, for example, is 787.3 kJ/mol, which is only slightly less than the energy given off when natural gas burns.

The bond between ions of opposite charge is strongest when the ions are small.

The ionic bond should also become stronger as the charge on the ions becomes larger.

Answer:

Thomson discovered that the atom contained smaller particles called electrons. The correct option is D.

What is Dalton's atomic model?

Dalton proposed that all matter is composed of tiny indivisible particles known as atoms, which he envisioned as "solid, massy, hard, impenetrable, movable particle(s)."

Thomson's experiment altered Dalton's atomic model by revealing the existence of smaller particles known as electrons within the atom.

The first part of his theory states that all matter is made up of indivisible atoms. According to the second part of the theory, all atoms of a given element have the same mass and properties.

One of Dalton's most important contributions is that it does not violate several fundamental laws of chemical combination, including the law of definite proportions, the law of multiple proportions, and the law of conservation of mass.

Thus, the correct option is D.

what is the standard form of 12,341 us?

Answers

Answer:

12341 in standard form = 1.2341 × 10⁴

Explanation:

When you split the number 12341 into a coefficient and a power of 10 you do get 12341 in exponential form, but there is an indefinite number of possibilities.

As you probably want 12341 in normalized scientific notation, the coefficient or significand of 12341 in scientific notation must be in the interval [1,10[.

As there are many ways to express 12341 in scientific notation, in this post we mean 12341 in normalized scientific notation, unless stated otherwise. Therefore:

12341 in scientific notation = 1.2341 × 10⁴.

This can also be expressed as 1.2341 × 10⁴, using the caret symbol, or as 1.2341e+4, which is called 12341 in e-notation.
