Your classmate says that the farther the two atoms are apart in a bond, the larger the dipole moment will be, this statement is correct.

An enduring attraction between atoms or ions known as a chemical bond is what allows molecules and crystals to form. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds.

Chemical bonds are formed when the atoms in a compound's molecule are brought together and kept together by a powerful combining force. Ionic and covalent bonds are the two different kinds of chemical bonding.

Atoms trade or exchange valence electrons to create bonds. The electrons at an atom's outermost energy level, known as valence electrons, have the potential to interact chemically. All chemical bonds are built on valence electrons.

Thus,  the farther the two atoms are apart in a bond, the larger the dipole moment will be, this statement is correct.

Answer:

Heavy stars turn into supernovae, neutron stars and black holes whereas average stars like the sun end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, however, follow roughly the same basic seven-stage life cycle, starting as a gas cloud and ending as a star remnant.

Answer: HELP stands for - Heat Escape Lessening Posture.

Answer:

no change in the temperature of the gas.

Explanation:

isothermal process of a gas, can result to compression of the gas or expansion of the gas at a constant temperature (ΔT = 0).

For isothermal gas expansion, work is done in reducing the pressure of the gas by increasing its volume at a constant temperature. The change in the internal energy of this process is zero (ΔU = 0).

For isothermal gas compression, work is done in decreasing the volume of the gas by increasing its pressure at a constant temperature. The change in the internal energy of this process is also zero (ΔU = 0).

Therefore, when a gas undergoes an isothermal process, there is no change in the temperature of the gas.

"Iron bar magnets Fill a bowl or pan with some water. Find something that will float on the water. Lay the magnet on top of this object. The magnet will twirl in the water until it comes to rest pointing exactly north and south due to the magnetic force of the North Pole."-- science.howstuffworks.com.  Or you could just increase the surface area.

Explanation:

The strength of the magnet force is maximum at the poles and minimum at the centre. A magnet can exerts a magnetic force on the other magnets as well. Here by using the soft iron bar as the magnet, the strength of the magnetic force on an object can be increased.

A magnetic force is defined as the force that a magnet exerts on certain materials like iron, steel, nickel, etc. This type of force is a non-contact force because it can act from a distance.

By using iron bar magnet or by increasing the numbers of turns of the coil can pick up more paper clips.

Answer:

107.5252955kPa or 108kPa

Explanation:

Use Gay Lussac's Law, P1/T1 = P2/T2

Manipulate the equation: P2 = P1*T2/T1

Change C to K: 35.6C = 308.75K and 17.3 = 290.45K

Input the values: P2 = (114.3kPa)(290.45K)/308.75K

P2= 107.5252955kPa

You probably want to round to 3 sig figs, so 108kPa

Answer:

5867ml is the answer to 5.867L to ml

Answer:

0.531 mole/L = 0.531M

Explanation:

What NaCl concentration results when 294 mL of a 0.750 M NaCl solution is mixed with 637 mL of a 0.430 M NaCl solution?

294 ml X 0.75 moles/1000ml=0,294X0.750 = 0.2205 moles

637 ml X 0.430 moles/1000ml = 0.637 X 0.430= 0.2739 moles

0.2205 + 0.2739                        = 0.4944 moles

this is distributed over 294 ml + 637 ml= 931ml

with a concentration of   0.4944 moles/0.931L or 0.531 mole/L = 0.531M

The statement 'polycrystalline materials have misoriented crystalline grains because phase transformations occur via a nucleation and growth process' is TRUE. Polycrystalline materials consist of many crystallites.

Polycrystalline materials are solid materials consisting of many crystallites, which vary in both size and orientation.

Polycrystalline materials include, among others, rocks, ice, metals, ceramics, etc.

Nucleation refers to the chemical process by which solid crystals form from a liquid.

In the solidification of polycrystalline materials via nucleation, molecules are first arranged in a particular pattern form which additional particles can be added as the crystal grows.

1 mole of Mg = 24 g

From the balanced equation above,

2 Faradays produced 24 g of Mg.

From the balanced equation above,

2 Faradays produced 24 g of Mg

Therefore,

3 Faradays will produce = (3 × 24) / 2 = 36 g of Mg

Answer:

Explanation:

An object that requires a larger force to accelerate has a greater mass and greater inertia. Hence, option A is correct.

A property of matter by which it remains at rest or in motion in the same straight line unless acted upon by some external force.

The more mass found in an object, the more inertia it contains and therefore the greater its tendency to resist change.

That is precisely why applying a net force on two objects of different masses will cause the lighter mass to accelerate more than the object that has a higher mass.

An object that requires a larger force to accelerate has a greater mass and greater inertia. Hence, option A is correct.

Only the number of particles of product equals the number of particles of reactants.

Could be more than one answer

Hydrogen 1 + Lithium 7 yields 2 Helium 4 plus energy

you have merged hydrogen 1  with Lithium 7 to produce a temporary berylium8, so it is fusion, because you are fusing the particles together.

the energy of the impact of the hydrogen on the lithium

causes the temporary berylium 8 to split into 2 helium atoms, so it is then fission, because you are splitting an atom of berylium8.

the mass of the reactants and products are not equal, because some of the energy comes from conversion of the reactant mass to energy by E=mcc

The number of reactant particles does equal the number of product particles, bute answer says ONLY which is not correct

In the given reaction, The mass of the products is exactly equal to the reactants. However this a radioactive  process where, lithium and hydrogen react together forming two helium nuclei.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the total mass of a system is conserved. In a closed system the mass cannot be lost.

For a chemical reaction, new products are formed by regrouping of atoms from the reactants where no new atom is produced not any lost. Hence, the total mass in the reactant side will be equal to the total mass in the product side.

In the given reaction the number of particles are equal in both side as well mass too equal in both side. The total mass in reactant side and product side is 8.
