Answer:

Narcotics

I think ans is

Explanation:

tropicaia

Ecstasy, also known as MDMA, is used recreationally, so it can be called a club drug. However, it is illegal in the US, so it would be considered a narcotic as well. The effects it has are also of the stimulant variety, so they would fall under that category as well. It is definitely not a depressant.

Answer:

this is because of collisions of molecules present in that particular system.

Explanation:

For instance, when air is filled in a balloon then the number of the molecules of air inside the balloon increases. As a result more collisions of molecules take place with the walls. This gives rise to high air pressure on the walls which causes the balloon to expand and get inflated.

Answer:

Wt Avg At Mass = 39.0229 amu

Explanation:

The Weight Average Atomic Mass in atomic mass units (amu) is the sum of the Weight Average Mass contributions of each isotopic mass. That is,

Wt. Avg. At. Mass (amu) = ∑ Wt. Avg. Contributions of each isotopic mass

Wt. Avg. Contribution = fractional abundance x isotopic mass(amu)

For this problem data:

Isotope   %Abundance     fractional         Isotopic             Wt Avg Isotopic

                                        abundance      mass(amu)        Contribution (amu)

   1                  9.67%           0.0967               38                      3.6746 amu

   2               78.68%           0.7868               39                    30.6852 amu

   3                 11.34%           0.1134                 40                      4.5360 amu

   4                  0.31%           0.0031                41                       0.1271  amu

Answer:

XY bond is the least polar

Explanation:

Given

[tex]W = 1.0[/tex]

[tex]X = 2.0[/tex]

[tex]Y = 2.5[/tex]

[tex]Z = 3.5[/tex]

Required

The least polar bond

First, we calculate the difference in the electronegativities

[tex]WX = X - W[/tex]

[tex]WX = 2.0 - 1.0[/tex]

[tex]WX = 1.0[/tex]

[tex]WY = Y - W[/tex]

[tex]WY =2.5 - 1.0[/tex]

[tex]WY =1.5[/tex]

[tex]WZ =Z-W[/tex]

[tex]WZ =3.5 - 1.0[/tex]

[tex]WZ =2.5[/tex]

[tex]XY = Y -X[/tex]

[tex]XY = 2.5 -2.0[/tex]

[tex]XY = 0.5[/tex]

[tex]XZ = Z -X[/tex]

[tex]XZ = 3.5 -2.0[/tex]

[tex]XZ = 1.5[/tex]

[tex]YZ = Z - Y[/tex]

[tex]YZ = 3.5 - 2.5[/tex]

[tex]YZ = 1.0[/tex]

The least of the above calculations will be the least polar.

Hence, XY is the least polar

Explanation:

Molecular formula of Decanoic Acid is  C₁₀H₂₀O₂ therefore Option A is the right answer.

Decanoic Acid is a C10 , straight chain , saturated fatty acid . Its general formula is C₁₀H₂₀O₂ .

In the first option we can see a straight chain , saturated fatty acid and the molecular formula is also same as decanoic acid .

In second option the molecular formula is C₉H₁₈O₂ which is not same as Decanoic Acid.

Hence option A is the right answer.

Explanation:

The easiest method to separating magnets is to slide them apart. When separating magnets keep in mind shear force. Magnets are measured on pull strength, so are up to five times easier to move if they are pushed apart instead of pulled apart. Small magnets slide relatively easily, even without spacers.

Firmly slide them away from each other and far enough apart so that they don't hop back together. Neodymium magnets are quite strong.

The properties of the magnet are:

Answer:

Describe what is happening within the system when it is at equilibrium in terms of concentrations, reactions that occur, and reaction rates.

Explanation:

The chemical equilibrium state is the state where the rate of forward reaction becomes equal to the rate of backward reaction.

At this stage the change in concentration of reactants becomes equal to the change in concentration of products.

The reaction will never cease.

That is the reason chemical equilibrium is called dynamic equilibrium.

So, forward and backward reactions will be taking place continuously at equal rates.

Answer:

Los dos óxidos que forma el cobre son óxido de cobre (I) y óxido de cobre (II) (Cu₂O y CuO, respectivamente).

Explanation:

El cobre posee dos estados de oxidación más comunes, los cuales son +1 y +2.

En contacto con aire el cobre se puede oxidar para dar lugar al óxido cuproso u óxido de cobre (I):

4Cu + O₂ → 2Cu₂O

Dicha oxidación también puede dar lugar a la formación del óxido cúprico u óxido de cobre (II):

2Cu + O₂ → 2CuO

La formación del óxido cúprico se favorece a temperaturas mayores a la del ambiente (por encima de los 300 °C).

Por lo tanto, los dos óxidos que forma el cobre son óxido de cobre (I) y óxido de cobre (II) (Cu₂O y CuO, respectivamente).

Answer: A decrease in population due to health threats is a possible consequence of decreasing air quality resulting from global warming.

Explanation:

When average temperature of Earth keeps on increasing for a longer period of time due to greenhouse gases, increased level of carbon dioxide and other gases etc then it is called global warming.

As humans use oxygen to sustain which is present in the air. So, when there will occur decrease in air quality that results from global warming then it means more illness or diseases will be there.

Hence, people will tend to die more often because of decrease in the air quality their health is getting affected.

Thus, we can conclude that a decrease in population due to health threats is a possible consequence of decreasing air quality resulting from global warming.

Answer: The molecular weight of the dibasic acid is 89.6 g/mol

Explanation:

Normality is defined as the amount of solute expressed in the number of gram equivalents present per liter of solution. The units of normality are eq/L. The formula used to calculate normality:

[tex]\text{Normality}=\frac{\text{Given mass of solute}\times 1000}{\text{Equivalent mass of solute}\times \text{Volume of solution (mL)}}[/tex]      ....(1)

We are given:

Normality of solution = [tex]\frac{1}{20}=0.05N[/tex]

Given mass of solute = 0.56 g

Volume of solution = 250 mL

Putting values in equation 1, we get:

[tex]0.05=\frac{0.56\times 1000}{\text{Equivalent mass of solute}\times 250}\\\\\text{Equivalent mass of solute}=\frac{0.56\times 1000}{0.05\times 250}=44.8g/eq[/tex]

Equivalent weight of an acid is calculated by using the equation:

[tex]\text{Equivalent weight}=\frac{\text{Molar mass}}{\text{Basicity}}[/tex]   .....(2)

Equivalent weight of acid = 44.8 g/eq

Basicity of an acid = 2 eq/mol

Putting values in equation 2, we get:

[tex]44.8g/eq=\frac{\text{Molar mass}}{2eq/mol}\\\\\text{Molar mass}=(44.8g/eq\times 2eq/mol)=89.6g/mol[/tex]

Hence, the molecular weight of the dibasic acid is 89.6 g/mol
