Answer:

Intensive Properties:  Appearance, State, Reactivity, Density

Extensive Properties:  Mass, Volume

Explanation:

Intensive Properties:  Appearance, State, Reactivity, and Density values all stay the same, regardless of the amount of material.

Extensive Properties:  Mass, and Volume depend on the amount of material present

Mass and volume are extensive properties.

Physical state, densities, appearances, and reactivities are intensive properties.

Explanation:

In the table given, we can see:

Mass and volume are extensive properties.

The physical state, densities, appearances, and reactivities are intensive properties.

Answer:

The gas particles would have higher Kinetic energy.

Explanation:

From the formular of kinetic energy:

[tex]{ \sf{KE = \frac{1}{2}m {v}^{2} }}[/tex]

KE is the kinetic energy possessed by particle.

KE is the kinetic energy possessed by particle.m is the particle mass.

KE is the kinetic energy possessed by particle.m is the particle mass.v is the velocity attained by a particle

[tex]{ \sf{KE = \{ \frac{1}{2} m \}} {v}^{2} }[/tex]

keeping the mass, m constant:

[tex]{ \sf{KE = k {v}^{2} }}[/tex]

Therefore, KE is directly proportional to v² :

[tex]{ \sf{KE \: \alpha \: {v}^{2} }}[/tex]

so, when velocity increases, KE also increases.

Answer:

3 is the answer.

Explanation:

Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.

Answer:

3

Explanation:

i believe the answer is B: both wind up at 60°C

but it's also reasonable to assume, given enough time, they wind up at 20°C because the water would heat up to cool the metal then slowly release the heat to the air untill they both reach 20°C

if it were me I'd answer B, apologies if I'm wrong

Answer:

Independant variable

Explanation:

Say you were doing a lab, you wanted to know if fertilizer actually helped a plant grow. The growth of a plant, in this situation, depends on whether you use fertilizer or not. You are changing if you use it or not, so it is the independent variable.  

Answer:

The average speed is = 11.1m/s

Explanation:

Recall that average speed is defined as the total distance traveled with respect to the total number of time, therefore we say that the total distance traveled is 40Km according to your question, remember, the unit of speed is metre per second, so you change 40km by multiplying it with 1000, recall that, 1000m = 1km, so 40km×1000m = 40,000m, also 1h= 60×60, =3600s

Remember the formula for average speed is = Total distance traveled÷ total time taken

Thus; 40000m/3600s

Then we had, 11.1m/s...

The two substances can never be separated by distillation because distillation depends on difference in boiling point.

Distillation is a separation method that depends on difference in boiling point between two substances.

Usually, the substance having a lower boiling point is collected first as the temperature is gradually raised. The substance having a higher boiling point then follows.

However, since the two substances have the same boiling point, they can not be separated by distillation because they will be converted to vapor simultaneously thereby making separation impossible.

Heating the liquids and letting one boil away first :)

Explanation:

Heating the liquids and letting one boil away first will be used to  separate the two liquids.

Two liquids that quickly form a solution when combined are called  miscible liquids.To Separate them, The best decision from the option is to heat the liquids and let one boil away first.

This is a separating method  or techniqe called Distillation where two miscible liquids example water and ethanol  are separated by Distillation due to the difference in boiling point. The liquid with the lower boiling point boils first and evaporates   or trapped in another tube  flask while the other with higher boiling point remains .

Copper Sulphate (CuSO₄) + Iron (Fe) → __Ferrous Sulphate ( FeSO₂)__ + Copper ( Cu)

Since we know the reactants and one of the products, we can work backward to discover what the other reactant may be.

As it is in the question, we can map the reactants and product:  

Reactants                   Product

Copper                        Copper  

Sulphate                      _____

Iron                               _____

This indicates that the product is a combination of Iron and Sulphate. Since Sulphate is of Valency two and Iron would want to match this valency, the likely product is Iron (II) Sulphate, commonly known as Ferrous Sulphate.

Extensive properties depend on the amount of matter in a sample, While Intensive properties do not depend on the amount of matter in a substance.

Answer:

[tex]\boxed {\boxed {\sf 2.8 \ g/mL}}[/tex]

Explanation:

Density is an object's mass per unit volume. The formula for calculating density is:

[tex]\rho= \frac{m}{v}[/tex]

The mass of the object is 5.8 grams and the volume is 2.1 milliliters.

Substitute the variables into the formula.

[tex]\rho = \frac{5.8 \ g}{2.1 \ mL}[/tex]

Divide.

[tex]\rho = 2.761904762 \ g/mL[/tex]

The original values of mass and volume (5.8 and 2.1) have 2 significant figures, so our answer must have the same. For the number we calculated, that is the tenths place. The 6 in the hundredth place tells us to round the 7 in the tenth place up to an 8.

[tex]\rho \approx 2.8 \ g/mL[/tex]

The density of the object is approximately 2.8 grams per milliliter.

Answer: The density of the rock is 3.03

Explanation:

Density formula:

P = mass/volume

= 170/56

= 3.03

Note: cannot measure density, so there is no sign beside it.
