Explanation:

An empty beaker weighs 34.49 g. when completely filled with water, the beaker and its contents have a total mass of 299.25 g. Volume does the beaker hold 264.76 mL.

mass of water = total mass - mass of beaker

mass of water = 299.25 g - 34.49 g

mass of water = 264.76 g

density of water = mass / volume

volume = mass / density

V = 264.76 g / 1.00g/mL

V = 264.76 mL

A physical body's overall composition is measured by its mass. This term also measures inertia, or the body's resistance to acceleration when a net force is applied. The strength of an object's gravitational pull to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit.

Like charges repel while the unlike charges attract.

Electrostatics has to do with the interaction that does occur between charges. We know that a charge is a specie that has an imbalance in the number of electrons that it contains. The substance is positively charged if it contains less electrons and more protons. The substance is negatively charged if it contains more electrons and less of protons.

In either case, the interaction that exist between particles could be an attractive one or a repulsive one. It is regarded as the first law of electrostatics that like charges repel while the unlike charges attract.

Hence when we look at the table, a negative charge would repel another negative charge, a positive charge would repel another positive charge but a positive or a negative charge would attract a charge of opposite sign. The interaction that is possible between the charges is given by Coulombs law.

Scandium(III) fluoride, ScF3, is an ionic compound. It is slightly soluble in water but dissolves in the presence of excess fluoride to form the ScF63− anion.

hope it will help you......

A high melting point is caused by a high fusion heat, a low fusion entropy, or a blend of the two. The crystal phase of highly symmetrical molecules is densely packed with many efficient intermolecular interactions, resulting in a higher enthalpy change on melting.

An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.

The intermolecular forces can be in order of strength, ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.

Because it is the power of attraction or repulsion between atoms or molecules rather than the ability to share or give/take electrons.

ScF3, or Scandium(III) fluoride, is an ionic compound. It is only slightly soluble in water, but in excess fluoride it dissolves to form the ScF63 anion.

Thus, due to the strong intermolecular forces, it have high melting point.

Answer:

Every atom of an element will have the same number of protons

Explanation:

Protons are used to identify an element because every atom of an element will have the same number of protons.

Answer:

Number of moles = 3.82 mol

Explanation:

Given data:

Number of moles of CO₂ = ?

Mass of CO₂ = 168.2 g

Solution:

Number of moles = mass/molar mass

Molar mass of CO₂ = 44 g/mol

By putting values,

Number of moles = 168.2 g/ 44 g/mol

Number of moles = 3.82 mol

Answer:

Ring is made up off copper.

Explanation:

Given data:

Mass of ring = 89.2 g

Volume of water = 10 mL

Volume of water + ring = 20 mL

Ring is made up of = ?

Solution:

Volume of ring = (Volume of water + ring) - Volume of water

Volume of ring = 20 mL - 10 mL

Volume of ring = 10 mL

Density:

Density = mass/volume     ( 1 mL = 1 cm³)

d = 89.2 g/  10cm³

d = 8.92 g/cm³

Thus, ring is made up off copper.

The correct answer for this question is Decreases.

How quickly or slowly a reaction proceeds is known as the rate of reaction or speed of reaction for a reactant or product. As the reaction progresses, the rate of reaction slows because the initial concentration of the reactants is high, but as time goes on, this concentration falls, making the reaction slower. As a result, the rate of reaction is dependent on concentration and diminishes over time.

Answer:

P₂ = 2.4 atm

Explanation:

Answer:

At higher altitudes, air pressure is lower. When atmospheric pressure is lower, such as at a higher altitude, it takes less energy to bring water to the boiling point. Less energy means less heat, which means water will boil at a lower temperature at a higher altitude.

In an ordinary container (exposed to atmospheric pressure). The freezing point will increase with altitude (and corresponding decrease in atmospheric pressure), but the difference is very slight.

Explanation:

When at a higher altitude , the atmospheric pressure is usually low and it

requires lesser amount of energy for the water to reach its boiling point. This

means that at higher altitudes , water boils at a lower temperature.

The freezing point of water increases with a higher altitude. This means that

water freezes at a higher temperature although the difference is very small.

The low pressure present in higher altitudes increases the melting point of

water(ice)

I am not sure why your teacher isn't asking for the layers, but here is the list of layers;

A -(topsoil) Mostly minerals from parent material with organic matter incorporated. A good material for plants and other organisms to live.

E - (eluviated) - Leached of clay, minerals, and organic matter, leaving a concentration of sand and silt particles of quartz or other resistant materials – missing in some soils but often found in older soils and forest soils.

B - (subsoil) Rich in minerals that leached (moved down) from the A or E horizons and accumulated here.

C - (parent material) The deposit at Earth’s surface from which the soil developed.

R - (bedrock) A mass of rock such as granite, basalt, quartzite, limestone or sandstone that forms the parent material for some soils – if the bedrock is close enough to the surface to weather. This is not soil and is located under the C horizon.
