What is the volume of a sample of matter with a density of 6 and a mass of 6 cm3?

Answers

Answer 1

Answer:

We have the final answer as

1.0 cm³

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density} \\[/tex]

From the question

mass = 6 g

density = 6 g/cm³

It's volume is

[tex]volume = \frac{6}{6} = 1 \\ [/tex]

We have the final answer as

1.0 cm³

What do metaloids share with nonmetals?

Answers

Answer:

Most metalloids have some physical properties of metals and some physical properties of nonmetals. They fall between metals and nonmetals in their ability to conduct heat and electricity. They are shiny like metals but brittle like nonmetals.

Explanation:

Atoms of the same element can have different forms; for example, carbon-12 and carbon-14.
What causes the different forms?


What are these forms called?

Answers

A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes. For example, carbon-14 is a radioactive isotope of carbon that has six protons and eight neutrons in its nucleus.

Carbon gets incorporated into marine organisms as organic matter or structural calcium carbonate.

What is the carbon cycle?

The carbon cycle describes how carbon moves between the atmosphere, soils, living creatures, the ocean, and human sources.

Carbon gets incorporated into marine organisms as organic matter or structural calcium carbonate. When organisms die, their dead cells, shells and other parts sink into deep water. Decay releases carbon dioxide into this deep water.

a race car at the Daytona 500 zips around the track .its travel the first 80 kilometers in 0.4 hours. the next 114 kilometers take 0.6 . the following 80 kilometers take 0.4 hours to calculate the race car average speed.

Answers

The answer to this should be around 40

A race car at the Daytona 500 zips around the track its travel the first 80 km in 0.4 hours, the next 114km take 0.6, the following 80 km take 0.4, so the average speed is 195.71 km/hr.

How do we calculate the average speed?

Average speed of any body will be calculated by dividing the total time to cover the ditance from the total distance covered.

Total distance to cover = 80km + 114km + 80km = 274km

Total time to cover distance = 0.4hr + 0.6hr + 0.4hr = 1.4hr

Average speed of car = 274/1.4 = 195.71 km/hr

So, the average speed of car is 195.71km/hr

What are the boiling points and freezing points (in oC)of a solution of 50.3 g of I2in 350 g of chloroform? The kb= 3.63 oC/m, the kf= 4.70 oC/m for CHCl3, and the molar mass of I2is 253.8 g/mol. The normal boiling point for CHCl3is 61.2 oC, and the normal freezing point for CHCl3is -63.5 oC.

Answers

Answer:

F.p   ≈  - 66.16⁰c

B.p  ≈ 59.1⁰c

Explanation:

Normal boiling point = 61.2⁰c

Normal freezing point = -63.5⁰c

Kb = 3.63⁰⁰ c/m

Kf = 4.70⁰ c/m

molar mass = 253.8 g/mol

solvent = 350 g = 0.35 kg

calculate The new freezing point and Boiling point

First we have to find the molality = number of moles / solvent in kg

= 0.198 / 0.35 = 0.5657 M

Hence the new freezing point can be calculated as

Normal freezing temp -  new freezing temp = Kf * molality

= -63.5 - F.p = 4.7 * 0.5657

F.p = -63.5 - 2.6588 ≈  - 66.16⁰c

Boiling point

Normal boiling point - new boiling point = Kb * molality

= 61.2 - B.p = 3.63 * 0.5657

B.p = 61.2 - 2.0535 ≈ 59.1⁰c

The measured pH of a solution of 0.010 HCl and 0.090 KCl at 25 degree Celsius is 2.102. Calculate the activity coefficient of H+ in this solution.C. Why does the pH change in part B relative to that in part A?

Answers

Answer:

activity coefficient [tex]\mathbf{\gamma =0.809}[/tex]

activity coefficient [tex]\mathbf{\gamma = 0.791}[/tex]

The change in pH in part A = 0.092

The change in pH in part B =  0.102

Explanation:

From the given information:

pH of HCl solution = 1.092

Activity of the pH solution [a] = [tex]10^{-1.092}[/tex]

[a] = 0.0809 M

Recall that [a] = [tex]\gamma[/tex] × C

where;

[tex]\gamma[/tex]  = activity coefficient

C = concentration

Making the activity coefficient the subject of the formula, we have:

[tex]\gamma = \dfrac{[a]}{C}[/tex]

[tex]\gamma = \dfrac{0.0809 \ M}{0.100 \ M}[/tex]

[tex]\mathbf{\gamma =0.809}[/tex]

B.

The pH of a solution of HCl and KCl = 2.102

[a] = [tex]10^{-2.102}[/tex]

[a] = 0.00791 M

activity coefficient [tex]\gamma = \dfrac{0.00791 \ M}{0.01 \ M}[/tex]

[tex]\mathbf{\gamma = 0.791}[/tex]

C. The change in pH in part A = 1.091 - 1.0 = 0.092

The change in pH in part B = 2.102 -2.00 = 0.102

A.134
B.90
C.125
D.110

Answers

A.134 sorry if it’s wrongggg

There are 110 neutrons in the stable isotope of rhenium. The correct option is D.

What are neutrons?

A neutron is a subatomic particle that exists in the nucleus of all atoms except simple hydrogen. The name of the particle comes from the fact that it has no electrical charge; it is neutral. Neutrons have a very high density.

With the exception of the single-proton hydrogen nucleus, nuclei require neutrons to be stable. Neutrons are abundantly produced during nuclear fission and fusion.

Through mainly the process of fission, fusion, as well as neutron capture processes, they are a major contributor to the nucleosynthesis of chemical elements within stars.

The element rhenium-185 is made up of 75 protons, 110 neutrons, and 75 electrons. The element rhenium-187 is made up of 75 protons, 112 neutrons, and 75 electrons.

Thus, the correct option is D.

The absolute temperature of a fixed mass of ideal gas is tripled while its volume remains constant. The ratio of the final pressure of the gas to its initial pressure is

Answers

Answer:

3 : 1

Explanation:

The following data were obtained from the question:

Initial temperature (T₁) = T

Initial pressure (P₁) = P

Final temperature (T₂) = 3T

Final pressure (P₂) =..?

Since the volume is constant, we shall use the following formula P₁ /T₁ = P₂ /T₂ to obtain the final pressure. This is illustrated below:

P₁ /T₁ = P₂ /T₂

P/T = P₂ /3T

Cross multiply

T × P₂ = P × 3T

Divide both side by T

P₂ = P × 3T /T

P₂ = P × 3

P₂ = 3P

Therefore, the final pressure is tripled.

Finally, we shall determine the ratio of the final pressure to the initial pressure as follow:

Initial pressure (P₁) = P

Final pressure (P₂) = 3P

Final pressure (P₂) : Initial pressure (P₁)

P₂ : P₁ => 3P/P

P₂ : P₁ => 3 : 1

Therefore, the ratio of the final pressure to the initial pressure is 3 : 1

We can first compute the moles of air at the given conditions of 195 kPa (1.92 atm), 10 °C (283K) and 350 L:

[tex]n=\frac{PV}{RT}=\frac{1.92atm*350L}{0.082\frac{atm*L}{mol*K}*283K}\\ \\n=29.03molAir[/tex]
