What is the formula for calculation of acceleration?

The answer is FALSE. I did it on ck-12

Answer:

1, 2 & 3

Explanation:

. A chemist investigates the boiling point, melting point, and flammability

of a compound called acetone, a component of nail polish remover.

Which of these properties are physical properties and which are

chemical properties?

Physical ( boiling point and melting point ).

Chemical ( flammability )

Among the properties listed (melting point, flammability, and boiling point), only the flammability of acetone is a chemical property. The other properties (melting point and boiling point) are physical properties since they are associated with changes in state .

The correct option is 1 .

The melting point of a substance is the temperature at which it changes from a solid to a liquid state. This is a physical property because it does not involve a change in the chemical composition of the substance. However, acetone is a liquid at room temperature, and therefore, it does not have a well-defined melting point. It would vaporize (evaporate) instead of melting.

Flammability is a chemical property. It refers to the ability of a substance to undergo combustion when exposed to a flame or ignition source. It involves a chemical reaction, as the substance interacts with oxygen to produce heat and light.

The boiling point of a substance is the temperature at which it changes from a liquid to a gas state. This is a physical property, similar to the melting point, as it does not involve a change in the chemical composition of the substance.

Hence , 1  is the correct option

what you need:

1 part aloe vera gel or glycerin

2 part isopropyl alcohol (rubbing alcohol) with a concentration of 91%

Essential oil, such as lemon or lavender (this is an optional ingredient for scent)

Clean containers for mixing and an air-tight container for storage

Spoon or whisk for mixing

Explanation:

step:

Combine the aloe vera gel or glycerin with the isopropyl alcohol in a clean container. To get one cup of sanitizer, combine ⅓ cup of gel or glycerin with ⅔ cup of rubbing alcohol.

Mix thoroughly with your spoon or whisk to ensure that the alcohol is evenly distributed throughout the gel.

Stir in five drops of an essential oil, if you're using it. This is entirely optional and is only meant to improve the scent of the sanitizer.

Store the sanitizer in an air-tight container. Alcohol evaporates with time, so an air-tight container will keep your sanitizer effective for longer. A pump or squeeze bottle can minimize evaporation while keeping your sanitizer easily accessible — just make sure the container for your sanitizer is clean and air-tight

The volumes that are equal to one liter are 1 dm and 1000 cm and can be seen in Option B and D respectively. The information below shows the calculation to arrive at the answer.

Dimensional analysis can be defined as the method of conversion from one given unit to another. It is often required to deal with measures that are extremely small (e.g size of an atom) or extremely big, In such circumstances, a conversion between metric measuring units is typically essential.

We are to determine which volumes in the given option are equal to 1 Liter.

Following the International System of Units (SI);

a.

10° nl = 10 nanoliters

10 nanoliters = 1 × 10⁻⁸ Liters

∴

It is incorrect

b.

1 dm = 1 cubic decimeter

1 cubic decimeter is equivalent to 1 Liter.

∴

Option B is correct

c.

10 ml = 10 milliliters

10 milliliters = 0.01 Liter

∴

Option C is incorrect

d.

1000 cm = 1000 centimeters

1 cm = 0.001 Liter

∴

1000 cm =  1 × 0.001 Liters

1000 cm =  1 Liters

Option D is correct

e.

100 dL = 100 deciliters

1 deciliter = 0.1 Liters

∴

100 deciliters = 10 Liters

As such, this option is also incorrect.

Therefore, we can conclude that Only Option B and D are the volumes that are equal to one Liter.

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.

Explanation:

elements like iron or copper consist of only one type

Answer:  V1/V2 = 0.357,

V2 = (V1/0.357) or 28.0*V2

Explanation:  Use the combined gas law:  P1V1/T1 = P2V2/T2  We want to find V1/2 (or V2/V1).  Rearrange:

V1/V2 = (P2/P1)(T1/T2)

The units all cancel.  Temerature is constant, so (T1/T2) = 1.

V1/V2 = (125/350)*(1)

V1/V2 = 0.357

The statement that is true about the system is; " The molecules in the system have more kinetic energy than solid".

There are three states of matter

The difference between these states of matter lies in the magnitude of intermolecular interaction between particles as well as the kinetic energy of the particles of the substance.

Solid particles have the strongest intermolecular interaction hence they have the lowest kinetic energy.

The magnitude of intermolecular interaction is weaker in liquids than in solids therefore liquid particles have greater kinetic energy than solid particles.

Lastly, gas particles have the greatest kinetic energy because intermolecular forces between them is almost negligible.

Liquids have volume but no definite shape. The description in the question must refer to a liquid system.

Answer:

First of all, Energy is released when water molecules bond.

Explanation:

When a bond is formed its stability increases from their respective atoms.  So energy is released but when we are breaking a bond we are changing a compound to a lower energy state to higher energy state it's stability decreases and requires a bit of extra energy higher stability of bond higher energy required to break it…
