Answer:

Objects in space follow the laws or rules of physics, just like objects on Earth do. Things in space have inertia. ... The movement of things in space is influenced by gravity. Gravity is an important force that can change the course of bodies in space or pull them off of one course, or even cause them to crash together.

Answer:

Recall the two conceptual steps necessary to dissolve a solute and form a solution

Key Points

There are two conceptual steps to form a solution, each corresponding to one of the two opposing forces that dictate solubility.

The first conceptual step is dissolution, which corresponds to the force of the solvent-solvent and solute-solute intermolecular attractions that needs to be broken down.

The second conceptual step is solvation, which corresponds to the force of the solute-solvent intermolecular attraction that needs to be formed in order to form a solution.

Many intermolecular forces can contribute to solvation, including hydrogen bonding, dipole-dipole forces, Van Der Waals forces, and ion-dipole interactions.

Term

intermolecular forcesattractive and repulsive forces between molecules

The strength of the intermolecular forces between solutes and solvents determines the solubility of a given solute in a given solvent. In order to form a solution, the solute must be surrounded, or solvated, by the solvent. Solutes successfully dissolve into solvents when solute-solvent bonds are stronger than either solute-solute bonds or solvent-solvent bonds.

Qualitatively, one can determine the solubility of a solute in a solvent by using the rule “like dissolves like”. In general, solutes whose polarity matches that of the solvent will generally be soluble. For example, table salt (NaCl) dissolves easily into water (H2O) because both molecules are polar.

Intermolecular Forces and Their Importance in Solution Formation

There are two conceptual steps to form a solution, each corresponding to one of the two opposing forces that dictate solubility. If the solute is a solid or liquid, it must first be dispersed — that is, its molecular units must be pulled apart. This requires energy, and so this step always works against solution formation (always endothermic, or requires that energy be put into the system).

Answer:

[tex]\boxed {\boxed {\sf 101.96 \ amu}}[/tex]

Explanation:

Formula mass is the sum of the atomic masses of the atoms in a molecule. Essentially, it is the mass of 1 molecule of a compound.

We are given a compound containing 2 aluminum atoms and 3 oxygen atoms. We will use the Periodic Table to look up the atomic masses of the 2 elements in the compound.

These are the atomic masses of 1 atom of the element. Remember we have 2 Al atoms and 3 O atoms. We multiply the element's atomic mass by the number of atoms of that element in the compound.

Now we add the atomic mass of 2 Al atoms and 3 O atoms.

We may want to round this answer to the hundredth place. The 0 in the thousandth place tells us to leave the 6 in the hundredth place.

The formula mass of a compound with 2 aluminum atoms and 3 oxygen atoms is approximately 101.96 atomic mass units.

Answer:

The metal molecules inside start to vibrate faster, causing the solid to change to liquid if exposed to the intense temperature over a long period of time.

Explanation:

As my answer states, but for an explanation, lets say you are boiling an ice cube, it will start to turn into liquid water, that is because it has been exposed to that heat for a long period of time. The same will happen for the metal, if its exposed for long enough, it will turn into a liquid, then can be turned into a gas because the molecules are vibrating so quickly that they start to easily move apart.

Hope this helps, let me know if any more clarification is needed.

Answer:

Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

The zero calibration of the electronic balance allows to maintain the precision of one digit.

Electronic measurement equipment has a mechanism to set the zero of the measurement every time the equipment is turned on, this procedure must be carried out to eliminate:

The methods of regurgitating the zero of the balance consists of measuring the weight without masses and bringing this value to zero, in general by changing some adjustable parameter of the balance, for example magnetic field current, reference level with a beam of light.

With this calibration it will be achieved that there is always a precision digit in the readings.

With Electronic Balance Calibration it is possible to have a pressure digit

Explanation:

Gaseous gallium will consist of atoms separated from each other by a large distance and do not experience inter-particle attractive forces.

There are three states of matter;

Matter can exist in all these states of matter depending on the extent of inter-particle attractive forces in the substance.

Inter-particle attractive forces are strongest in solids hence they have a definite shape and volume and do not flow.

Liquids have weaker inter-particle attractive forces than solids hence liquid particles can flow. Liquids have a definite volume but not a definite shape.

Gases have almost no inter-particle attractive forces between particles hence gas particles are separated by large distances and move at very high velocities. A gas does not have definite shape or volume.

A model of gaseous gallium will show atoms of gallium separated by large distances and do not experience inter-particle attraction.

A model of gas particles is shown in the image attached to this answer.

Answer:

Steel is an example of a solid-solid solution (aka an alloy).

Explanation:

The part of John Dalton’s theory was disproved by J.J. Thomson’s cathode-ray tube experiments is; "Atoms are indivisible".

One of the major postulates of the Dalton's atomic theory is that the atoms of elements are "indivisible".

This idea resounds from the earliest ideas of Greek philosophers concerning the atom.

Through the cathode-ray tube experiments, J.J. Thomson discovered sub-atomic particles.

This nullified the idea that atoms are indivisible.
