Answer: Molar mass of [tex]CuSO_4.5H_2O[/tex] is 249.68 g/mol.

Explanation:

Molar mass is the mass of 1 mole of the molecule. It is calculated by adding masses of all the atoms in the given molecule.

[tex]CuSO_4.5H_2O[/tex] contains one atom of copper , 1 atom of sulphur, 9 atoms of oxygen and 10 atoms of hydrogen

Mass of copper = 63.5  g/mol

Mass of sulphur =  32.06 g/mol

mass of oxygen = 16.00 g/mol

Mass of hydrogen = 1.008 g/mol

 Thus mass of [tex]CuSO_4.5H_2O[/tex] = 63.5(1)+32.06(1)+16.00(9)+1.008(10)=249.68 g

Molar mass of [tex]CuSO_4.5H_2O[/tex] is 249.68 g/mol.

Answer:

Its c newton third law

Explanation:

His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.

Answer:

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron setup, and repeating chemical properties. The structure of the table shows occasional (popular things/general ways things are going). The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with almost the same chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks connected with the filling of different atomic orbitals.

Answer:

pseudo first order

Explanation:

We know that for a first order reaction, the plot of the natural log of the amount of reactant against time is a straight line with a negative slope. In this case the amount of substance is monitored using the amount of light change. Hence, the plot of the natural log of the amount of light change against time was a straight line with a negative slope.

The statement above characterizes a first order reaction. However, we must remember that the reaction is bimolecular; it involves luminol and hydrogen peroxide. The hydrogen peroxide is 44 times more concentrated than the luminol making the reaction a pseudo first order reaction.

A Pseudo first-order reaction can be defined as a second-order or bimolecular reaction that is made to behave like a first-order reaction(Byjus).

Answer:

Land covers refer to all the manufactured structures and vegetation that covers the land it includes all vegetation including plants, shrubs, trees, and other man-made structures too.

On other hand, Land use is the term that explains the use of the land by the different human activities that are occurred on land that are directly related to the land.

Land cover influences land use by utilizing particular land such as parks, ponds, or other uses according to the land. and humans can cause changes in both when they urbanize the area or land.

Explanation:

magnesium acetate= Mg(C2H3O2)2

Answer:organic compound is :​ C₄H₈

Explanation: The equation of the reaction of the organic compound burning with excess oxygen gives us the general equation as

C xHy  + 1/2(x+ y/2 )O₂ → xCO₂ + y/2H₂O

We first find the number of moles of CO₂ and H₂O

Number of moles of CO₂= Mass/ molar mass

= 17.6g/ 44g/mol ( 12+ 16 x2)

=0.4 moles

Number of moles of H₂O= Mass/ molar mass

= 7.2g/ 18g/mol ( 1 X 2+ 16)

=0.4 moles

From the reaction , we can see that  

x = 0.4

and  [tex]\frac{y}{2}[/tex]= 0.4  such that y= 0.4 x 2= 0.8

Their ratios become

[tex]\frac{x}{y}[/tex] =[tex]\frac{0.4}{0.8}[/tex]= [tex]\frac{4}{8}[/tex]

Therefor the organic compound CxHy  = C₄H₈

The more metallic element  pair is Cl or O. Therefore, option C is correct.

Except for hydrogen, which is a nonmetal, the elements are arranged in a triangle with the metals to the left, the nonmetals to the right, and the metalloids to the immediate right of the triangle.

Metal atoms are bound together by metallic bonds to form solids known as metallic solids. Metal solids include things like copper, gold, and zinc, for instance. Since cesium is the last naturally occurring alkali metal, it has the most metallic characteristics.

The non-metal components, like as rock and rubbish, are subsequently removed from the ore during processing. The subsequent melting and combining of various metal components yields metal alloys. A solid metal alloy substance is produced when the freshly combined metal compound has cooled.

Thus, option C is correct.

Answer:

Explanation:

That's correct. Once Aluminum becomes an ion, it is very hard to force it to take back its electrons. Only a few elements can do it. Iron is not one of them.

Answer:

You see the concentration decreased ten fold, from 1 M to 0.1 M.

You can simply increase the volume by ten times.

For example

If you have 250 mL of 1 molar HCl, you can add distilled water upto 2500 mL. Now the concentration is 0.1 molar.

If you want to use the serial dilution method, you can use the C1V1=C2V2 equation.

C1 = starting concentration.

C2 = final concentration.

V is for volume.

So let's say you have 500 mL of 1 M HCl and you only want 50 mL of 0.1 M HCl.

1 M x V1 = 0.1 M x 50 mL

V1 = 5 mL

So you take 5 mL of the original (stock) solution and dilute it up to 50 mL. Then you have 50 mL of 0.1 M HCl.

The correct options for Charles's law, Gay-Lussac's Law and Boyle's law are D, B and E respectively.

Charles's law states that, under the assumption of constant pressure, the volume of a gas increases or decreases with its temperature. As the temperature increases, the gas molecules move more quickly and occupy more space, increasing the volume of the gas.

Gay-Lussac's law states that, assuming a constant volume, the pressure and temperature of a gas are exactly related. Increasing temperature causes the gas molecules to become more kinetically energetic and collide with the walls of the container more frequently, increasing the pressure.

Boyle's law states that at a given temperature, the pressure and volume of a gas are inversely proportional. The reduced volume forces the gas molecules into a smaller area, increasing the chance of collisions with the container walls and pressure.

Therefore, the correct options for Charles's law, Gay-Lussac's Law and Boyle's law are D, B and E respectively.

Following are decreasing order to this question:

Explanation:

Viscosity and surface tension both are inter-molecular by nature (IMFs)

The pentane becomes non-polar and just not H-bondable, so LDF alone would be likely (London Dispersion Force)

Pentanal, but H-bond => is impossible (Dipole-Dipole)

Pentanol is also an OH group, so H-bond => is probable (Hydrogen Bonding)

Higher air tension and viscosity than higher IMFs (because the atoms of fluids are more drawn). To lower the IMF (and therefore the viscosity/surface stress decreases)

Answer:

2.765amu is the contribution of the X-19 isotope to the weighted average

Explanation:

The average molar mass is defined as the sum of the molar mass of each isotope times its abundance. For the unknown element X that has 2 isotopes the weighted average is defined as:

X = Mass X-19 * Abundance X-19 + MassX-21 * Abundance X-21

The contribution of the X-19 isotope is its mass (19.00 amu) times its abundance (14.55% = 0.1455). That is:

19.00amu * 0.1455 =

2.765amu is the contribution of the X-19 isotope to the weighted average
