Write 0.034 in scientific notation.

Answers

Answer 1

Answer:

0.034 = 34×10^-3

Explanation:

This is because the special point is notated until it goes in front of the first counting number

Answer 2

Scientific notation is a way of expressing numbers that are very large or very small in a compact and standardized format. 0.034 in scientifc notation is written as 3.4 × 10⁻³

In scientific notation, a number is expressed as the product of a coefficient and a power of 10. The coefficient is a decimal number greater than or equal to 1 but less than 10, and the power of 10 represents the magnitude of the number. The power of 10 indicates the number of places the decimal point must be moved to obtain the original number.

For example:

The number 4,500,000 can be written in scientific notation as 4.5 x 10⁶, where the coefficient is 4.5 and the power of 10 is 6.

The number 0.000043 can be written in scientific notation as 4.3 x 10⁻⁵, where the coefficient is 4.3 and the power of 10 is -5.

Scientific notation allows for easy representation of very large or small numbers and simplifies calculations involving these numbers. It is particularly useful in scientific fields where values such as distances, masses, and concentrations can vary over a wide range.

Which of the following volumes are equal to one liter? Select all that apply.

10° nl.
1 dm
10 ml
1000 cm
100 dL

Answers

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.

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

Answers

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).

Answers

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;

SolidLiquidGas

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.

The volume (V) of an enclosed mass of gas is 350kPa. The pressure of the endlosed gas is now decreased to 125kPa, at constant temperature. What will the new volume of the gas be, in terms of V (2)​

Answers

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
