Explanation:

The three things that can affect a condition to enforce a slide is friction, weight, and slope of an area. Solutions that can make flow easily are those that can create less friction depending on the condition of an environment where it is present.

Answer:

A

Explanation:

Answer:

Its particles are evenly distributed.

Explanation:

Solutions are homogenous mixtures of solutes and solvents. In a solution the solute particles are evenly distributed in the solvent.

Here are some characteristics of solutions:

A characteristic of a solution is that its particles are evenly distributed.

A characteristic of a solution is that its particles are evenly distributed. In a solution, the solute (substance being dissolved) is uniformly distributed and mixed with the solvent (the substance doing the dissolving) at the molecular or ionic level.

The particles of the solute become thoroughly dispersed and do not settle out over time. Solutions are generally clear and do not scatter light, unlike suspensions or colloids which may exhibit light scattering due to the presence of larger particles.

Answer:

False

Explanation:

Mixtures are impure substances.

There are two types of mixtures based on the number of coexisting phases.

Homogeneous mixtures have their constituents existing in one single phase. The components are evenly spaced.

Heterogeneous mixtures have their constituents existing in at least two different phases. Therefore, they are unevenly spaced due to the phases present within the mixture.

Answer:

3.51m/s

Explanation:

Given parameters:

Distance   = 20miles

         Miles to meters:

             1 mile  = 1609m

              20miles  = 20 x 1609  = 32180m

Time  = 153minutes

             1 min  = 60s

           153min  = 60 x 153  = 9180s

Unknown:

Average speed  = ?

Solution:

To solve this problem;

        Average speed  = [tex]\frac{distance }{time taken}[/tex]  

         Average speed  = [tex]\frac{32180}{9180}[/tex]   = 3.51m/s

INCREASE OF SOLAR WINDS When the sun is more active

Answer:

1. The Lewis structure for SO32- is structure B.

Note: See attachment for complete question and for formal charges of the atoms in each structure.

Explanation:

The formal charge of an atom in a molecule is the assumed charge the atom would have if the electrons in the bonds were evenly distributed between the atoms.

Formal charge can be calculated as follows:

Formal charge = number of valence electrons - ( number of non-bonding electrons + ½ bonding electrons)

Formal charges are used to determine the best possible Lewis structure of a molecule or ion. The following rules are applied:

1. A structure in which all formal charges are zero is preferable to one in which some formal charges are not zero.

2. If non-zero formal charges must exist in the structure , the arrangement with the smallest non-zero formal charges is most preferred.

3. Lewis structures are preferable when adjacent formal charges are zero or of the opposite sign.

4. The structure with the negative formal charges on the more electronegative atoms is preferred among other structures of the molecule or ion.

From the above rules, structure B has negative charges on the more electronegative oxygen atoms and has more zero formal charges on the atoms. The central atom, sulfur also has a zero formal charge.

PbN₂O₆

Explanation:

Empirical formula is the simplest formula of a compound.

To find the empirical formula, we use the system below:

Percentage

Composition              62.6                           8.4                          29

Moles                        62.6/207.2                 8.4/14                     29/16

                                      0.302                        0.6                        1.813

Divide by the

smallest                     0.30/0.302                   0.6/0.302          1.813/0.302

                                            1                                  2                           6

Empirical formula is PbN₂O₆

The empirical formula of the compound containing 62.60% lead, 8.40% nitrogen, and 29.0% oxygen is PbN₂O₆ or Pb(NO₃)₂

From the question given above, the following data were obtained:

Lead (Pb) = 62.60%

Nitrogen (N) = 8.40%

Oxygen (O) = 29.0%

The empirical formula of the compound can be obtained as illustrated below:

Divide by their molar mass

Pb = 62.60 / 207 = 0.302

Nitrogen (N) = 8.40 / 14 = 0.6

Oxygen (O) = 29.0 / 16 = 1.8125

Divide by the smallest

Pb = 0.302 / 0.302 = 1

Nitrogen (N) = 0.6 / 0.302 = 2

Oxygen (O) = 1.8125 / 0.302 = 6

Thus, the empirical formula of the compound is PbN₂O₆ or Pb(NO₃)₂

Answer:

Cyclopropane has a planar carbon back bone while propane does not

Explanation:

We have to recognize that in straight chain saturated organic compounds, carbon atoms have a tetrahedral geometry. Each carbon atom is bonded to four other atoms.

However, carbon atoms in cyclic compounds are also sp3 hybridized with each carbon bonded to only four other atoms but the ring system is highly strained.

Cyclopropane is a necessarily planar molecule with a bond angle that is far less than the expected tetrahedral bond angle due to strain in the molecule. Hence, the carbon atoms may have have a "planar backbone".

Answer: a. Millimeter

Explanation:

A paperclip is a small device or instrument that can be used to hold the papers or stack of papers together. The length of the paperclip can be measured using millimeter. It is equal to the thousands of meters. The millimeter is a dimension which is used to measure the very small length objects which have visible scale distances and length.

Decimeter can be used to measure the length of the object smaller than paperclips. Meter and kilometers are used for objects and distances larger than paperclip.

Answer:

So we are given with the mass while we are asked for the amount of volume. So this means, we must need an information on the density. From literature, the density of human fat is 0.918 g/cm³. Convert grams to lb by the conversion that 1,000 g = 2.2 lbs.

Density = 0.918 g/cm³ * (2.2 lbs/1,000 g) = 0.0020196 lb/cm³

Volume = Mass/Density = 12.2 lb / 0.0020196 lb/cm³

Volume = 6,040.8 cm³

Answer:

hydrogen, carbon, oxygen and nitrogen

Explanation:

Most organic compounds are made up of the four elements: hydrogen, carbon, oxygen and nitrogen.

Most organic compounds are made of just four elements are  hydrogen, carbon, oxygen and nitrogen.

The term organic compound is defined as a substance that contains covalently - bonded carbon and hydrogen and often with other elements.

Benzoic acid, aromatic compounds, benzoic aldehyde, propanoic acid, butanoic acid, malonic acid, amines, heterocyclic compounds, VOC, benzoic acid, and diethyl malonate are some examples of organic compounds.

Carbohydrates, lipids, proteins, and nucleotides are all organic compounds that are required for human function. Because they contain both carbon and hydrogen, these compounds are classified as organic.

Thus, Most organic compounds are made of just four elements are  hydrogen, carbon, oxygen and nitrogen.

Answer:

0.266 grams of calcium sulfate

Explanation:

We can calculate the mass of calcium sulfate added using the given volume and concentration of the solution:

First we convert 600.0 mL to L ⇒ 600.0 mL equals 0.6000 L (600 ÷ 1000).

0.444 g/L * 0.6000 L = 0.266 g

Thus the answer is 0.266 grams of calcium sulfate.

          NH₄NO₃ :

Problem here is to find the molar mass of the compound.

 Now;

The molar mass is the sum of the atomic masses of the elements in the compound.

   Atomic mass of N  = 14g

   Atomic mass of H  = 1g

   Atomic mass of O  = 16g

So;

   Molar mass = 14 + 4(1) + 1 + 3(16) = 67g/mol

Answer:

New kinds of products forms and the reaction is not easily reversible.

Explanation:

The only way to be certain that a chemical change has occurred is by finding out if new kinds of products have been formed.

A chemical change is a change in which new kinds of matter is formed. It is always accompanied by energy changes.

The process is not easily reversible.

Examples of chemical changes are combustion, rusting of iron, precipitation and souring of milk.

Answer:

Pressure = 0.62 atm

Explanation:

[tex]V_{1}[/tex] = 85 [tex]cm^{3}[/tex], [tex]P_{1}[/tex] = 1.45 atm,  [tex]T_{1}[/tex] = 310 K, [tex]V_{2}[/tex] = 180 [tex]cm^{3}[/tex], [tex]T_{2}[/tex] = 280 K.

Applying the general gas law,

[tex]\frac{P_{1} V_{1} }{T_{1} }[/tex] = [tex]\frac{P_{2} V_{2} }{T_{2} }[/tex]

[tex]\frac{1.45*85}{310}[/tex] = [tex]\frac{P_{2}*180 }{280}[/tex]

[tex]P_{2}[/tex] = [tex]\frac{1.45*85*280}{180*310}[/tex]

   = [tex]\frac{34510}{55800}[/tex]

   = 0.62

[tex]P_{2}[/tex]  = 0.62 atm

The pressure when the volume is increased and the temperature reduced to the given values is 0.62 atm.
