Write the correct term: In gaseous substances, the individual molecules are relatively (close/far apart) and are moving freely, rapidly, and randomly.

Answers

Answer:

far apart

Explanation:

The molecules of any gaseous compounds are loosely bound and the molecules are far apart from each other. They move freely and rapidly. The inter-molecular forces are lower as compared to a solid or a liquid where the molecules are comparatively closely bound in the compounds.  

Because of the large gap or distance between its molecules, gaseous compounds have less density  when compared to any solid or liquid.

What are the best units for a scientist to measure the distance between cities?
A. miles
B.inches
C.meters
D.kilometers

Answers

Answer: A and D

Explanation: Miles and Kilometers are the best units when measuring distances between cities, this is because both units will in most cases give a reasonable representation of the distance being measured by giving an output which isn't too large or extremely small. Feets and inches are usually adopted when measuring length of objects which in most cases are small and average only a few meters. Meters are also used for measuring short and medium distances. However, representing distances between two cities in terms of inches or feets will usually give extremely large values. Hence, the need for a fairly larger unit in miles or kilometers.

What is measurement?

Distance is a physical quantity which is measured in meter. If a man travel then it is measured in meters that defines that how much he travel from one point to another point for all these type of things we use to measure distance.

Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance.

Kilometer is also a physical quantity which use to measure the distance 1 kilometer is equal to 1000 mtr and 1 kilometer is equal to 100000 centimeter.

For above conclusion, we easily states that the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance.

Explanation:

A model of an atom shows eight electrons in rings that represent different energy levels. How many electrons are in each energy level? A.four in the first energy level, four in the second energy level. B.zero in the first energy level, eight in the second energy level C.two in the first energy level, six in the second energy level D.eight in the first energy level, zero in the second energy level

Answers

Answer:

The correct option is;

C. Two in the first energy level, six in the second energy level

Explanation:

The electrons in an atom are arrange in orbital shells which are situated at different levels within the structure of the, depending on the energy of the electron. Electrons with the least amount of energy are found in the shell closest to the nucleus of the atom which is the first energy level

The maximum number of electrons that can be found in a given an energy level is obtained with the following formula;

The number of electron = 2 × n²

Where;

n = The number of the different energy level

Therefore;

The maximum number of electrons in the first energy where n = 1 is given as follows;

The number of electron = 2 × 1² = 2 electrons

The maximum number of electrons in the second energy level where n = 2 is given as follows;

The number of electron = 2 × 2² = 8 electrons

Given that there are only 8 electrons in the atom, we therefore have, 2 electrons in the first energy level and the remaining 8 - 2 = 6 electrons in the second energy level.

What is the mass of a sample of iron that has had 300.0 j applied to it and heats up from 20.0 degrees Celsius to 40.0 degrees Celsius.. the specific heat of iron is 0.46j/gC

Answers

Answer:

The mass of a sample of iron that has had 300 J applied to it and heats up from 20 degrees Celsius to 40 degrees Celsius is 32.61 grams.

Explanation:

Calorimetry is the measurement and calculation of the measurement of heat changes exchanged by a body or a system produced in physical and chemical processes.

The sensible heat of a body is the amount of heat received or transferred by a body to produce a change in temperature but without a change in physical state.

The sensible heat in a constant pressure is calculated by:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c, and where ΔT is the temperature variation (ΔT=Tfinal - Tinitial)

In this case:

Q= 300 Jc= 0.46 [tex]\frac{J}{g*C}[/tex]m= ?Tfinal= 40 CTinitial= 20 C

Replacing:

300 J= 0.46 [tex]\frac{J}{g*C}[/tex] * m* (40 - 20) C

Solving:

300 J= 0.46 [tex]\frac{J}{g*C}[/tex] * m* 20 C

[tex]m=\frac{300 J}{0.46 \frac{J}{g*C} * 20 C}[/tex]

m= 32.61 g

Element, mixture, heterogeneous, Viscosity, compound

The carbon element  combines chemically with oxygen and hydrogen to form a compound known as sugar. When making syrup, the sugar is dissolved in water to make a mixture . Before the sugar and water are mixed, the heterogenous  mixture is not the same sweetness throughout. After mixing, the solution homogenous is because when sugar is evenly disbursed throughout the water. Finally, the water is slowly boiled off and the solution slowly becomes sticky and gooey because the viscosity has increased and the solution now resists flowing.

What do you mean the solution ?

A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase. A solution consists of a solute and a solvent.

For the solutions, with components in the same phase, the substances present in lower concentration are solutes, while the substance present in higher concentration is the solvent.

you have an object with mass of 86 g and volume of 10 cm^3 (cubed). calculate density, show your work, and identify which material you have from the list.​

Answers

Answer:

8.6g/cm³ (BRASS)

Explanation:

Given the following :

Mass of object = 86g

Volume of object = 10cm³

The density of an object is calculated using the formula :

Density(g/cm³) = mass(g) / volume(cm³)

Inputting our values :

Density = 86g / 10cm³

Density = 8.6g/cm³

According to the table provided, the object which corresponds to having a density of 8.6g/cm³ is BRASS

1. The density of the material is 8.6 g/cm³.  

2. The material is brass

Density is simply defined as the mass per unit volume of a substance i.e

Density = mass / volume

1. Determination of the density of the material

The density of the material can be obtained as shown below

Mass = 86 g

Volume = 10 cm³

Density =?

Density = mass / volume

Density = 86 / 10

Density = 8.6 g/cm³

Therefore, the density of the material is 8.6 g/cm³

2. Determination of the material.

From the calculation made above, the density of the material is 8.6 g/cm³.

Comparing the density of the material (i.e 8.6 g/cm³) with those

given in the table from the question, we can conclude that the

material is brass.

3) What is the weight of the ethyl alcohol that exactly fills a
200.0 mL container? The density of ethyl alcohol is 0.789
g/mL.

Answers

Answer:

158g

Explanation:

To calculate the "weight" (mass) of ethyl alcohol, we have to use this formula:

- Density will have units of gmL when dealing with a liquid or units of gcm3 when dealing with a solid.

The mass has units of grams, g.

The volume will have units of mL or cm3

We are given the density and volume, both of which have good units so all we have to do is rearrange the equation to solve for the mass:

density×volume=massvolume×volume

Density×Volume = Mass

0.789gmL×200.0mL

Thus, ethyl alcohol weighs 158g.
