(2) chromatography - separation can be based on the mobility of the phases (liquid chromatography, gas chromatography, ion-exchange, etc.)

(3) solvent extraction - if the components are both liquid, separation based on their relative solubilities

(4) distillation - separation based on different boiling points.

1) A. The reactants and products have the same number and type of atoms, but the atoms may be recombined.

2) B. It shows how many molecules there are of a particular substance.

3) D. NaOH + HCl → NaCl + H2O

4) A. Atoms always remain intact during chemical reactions.

5) D. 4, 4

The balanced chemical equation is:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

The numbers that balanced the equation are: 4, 4

To know the number that balanced the equation, we shall simply balance the equation.

CH₄ + Cl₂ —> CCl₄ + HCl

There are 4 atoms of H on the left side and 1 atom on the right side. It can be balance by writing 4 before HCl as shown below:

CH₄ + Cl₂ —> CCl₄ + 4HCl

There are 2 atoms of Cl on the left side and a total of 8 atoms on the right side. It can be balance by writing 4 before Cl₂ as shown below:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

Now, the equation is balanced

The numbers that balanced the equation are 4,4

Answer:

3.5 mol/L

Explanation:

First convert the 139.9g of LiCl into moles of LiCl.  Don't do the sig fig rule until the very end.

Second, take 930mL of LiCl and divide it by 1000 to convert it to liters.

Third use the molarity formula which is M=mol/L and divide 0.930L by 3.300773877mol and you will get 3.549219223.  This is where the sig fig rule will come into play.  3.5mol/L is a reasonable answer for this problem.

Answer:

The atmosphere and Earth's interior are layered by density. The differentiation between these layers is due to processes that took place during the early stages of Earth's formation (ca. 4.5 billion years ago). At this time, melting would have caused denser substances to sink toward the center while less-dense materials would have migrated to the crust.

Gravity pulls more strongly on denser materials so denser materials are at the center of things.

Explanation:

Gravity pulls more strongly on denser materials so denser materials are at the center of things. The lowest layer of the atmosphere is denser than the upper layer. Earth's liquid metal core has convection, which generates the magnetic field.

Denser materials are in the centre of the universe because they are more powerfully pulled toward the centre by gravity.

The force that pulls items toward the centre of a planet or other entity is called gravity. All of the planets are kept in orbit around the sun by gravity.

Gravity applies to anything that has mass. Gravity is stronger for objects with higher mass. Along with distance, gravity weakens as well. Therefore, the gravitational force of two things becomes stronger the closer they are to one another.

The mass of the Earth is what creates gravity. The total gravitational force of all of its mass acts on the weight in your body. What gives you weight is that. Additionally, you would weigh less than you do now if you were on a planet with a lower mass than Earth.

Gravity applies to anything that has mass. Gravity is stronger for objects with higher mass. Along with distance, gravity weakens as well. Therefore, the gravitational force of two things becomes stronger the closer they are to one another.

Therefore, denser materials are closer to the centre of the universe because gravity is more drawn to them.

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option C.

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

In the given molecule NH₃, the subscript 3 that is written on the foot of element represents the number of hydrogen atoms in each molecule of ammonia.

Therefore, the correct option is option C.

Answer:

Because, it would make the pan hot and if it's plastic then it would melt. if it was metal it might make the metal piece hot and you'd risk burning yourself.

Explanation:

You should never place a hot object on the pan of a balance because it can cause the balance to become inaccurate and affect the measurement results.

Balances are precision instruments used to measure the mass of objects with high accuracy. The balance pan and its components are designed to operate under specific conditions, including a stable temperature. When you place a hot object on the balance pan, several issues can arise:

Thermal Expansion: Materials, including metals and plastics, can expand when exposed to heat. Placing a hot object on the pan can cause the pan and its supporting components to expand, potentially affecting the balance's calibration and accuracy.

Uneven Heating: If the hot object is not uniformly heated, it can cause uneven expansion of the balance pan. This can lead to imbalanced weight distribution and inaccurate measurements.

Calibration Shift: The heat from the hot object can cause the materials in the balance to change temperature rapidly, potentially affecting the calibration of the instrument. The balance may require time to stabilize before accurate measurements can be obtained.

Damage to the Balance: Exposing the balance pan to extreme heat can cause warping, cracking, or other structural damage to the pan material. This can permanently impair the balance's performance and accuracy.

To ensure accurate measurements and maintain the integrity of the balance, it's important to allow hot objects to cool to room temperature before placing them on the balance pan. Additionally, using appropriate containers or holders designed for high-temperature applications can help prevent damage to both the hot object and the balance equipment.
