Answer:

Binary molecular (covalent) compounds are formed as the result of a reaction between two nonmetals.

Binary covalent compounds which have slight difference in their electronegativities can be named as a function of  the octet rule.

Covalent  compounds have covalent  bonds which  is defined as a type of bond which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.

Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.

Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

Answer:

A. proton is positive charged ans and is equal to electrons

Proton positively charged, mass about equal to that of an electron subatomic particle is correctly paired with its properties.

The correct option is A.

They include the heavier constituents of the small but extremely dense atom's nucleus, the positively charged protons and the electrically neutral neutrons, as well as the electrons, the negatively charged, nearly massless particles that still make up the majority of the atom's size.

Two subatomic particles are bound together by the strong nuclear force to form the atomic nucleus. The proton is one of these subatomic elements. The neutron is the other. Similar in size and mass to protons, neutrons are electrically neutral or devoid of any net electrical charge.

Answer:

Use the balanced equation to determine the theoretical yield. Focus on the chemicals whose quantities you are given or are asked to find. CO is not important as it is excess and will make sure that all of the Fe2O3 will be changed to iron. Remember the quotients (numbers in front of formula) are the number of moles. You are given the mass of Fe2O3 in grams so you will need to convert 1 mole of Fe2O3 into grams (molar mass which, using simple atomic masses = 56x2 + 16x3 = 160g/mol but you use atomic masses that your course requires

Fe2O3(s) + 3CO(g)--> 2Fe(s) + 3CO2(g)

1 mol 2 mol

160g 112g

84.8g (112/160) x 84.8

So now you have the theoretical yield of Fe2O3 and the experimental (actual) yield = 54.3g)

Percentage Yield = (actual yield/theoretical yield) x 100

The heating of the substance resulted in the transfer of energy and thereby increase the randomness. Thus, Alana's error can be rectified by switching the labels on the diagram.

The atoms are the smallest particles, and everything is made of atoms. The atoms in the object are arranged in a specific lattice to give shape to the object.

The heating resulted in the transfer of energy to the atoms, and the atoms started to move thereby will not be linearly arranged after heating.

Thus, the heating and the atomic arrangement effect can be explained by switching the labels on Alana's diagram. thus, option D is correct.

Explanation:

A refrigeration lubricant with a high floc point may have excessive wax separation, which can clog the system.

The Floc point of the oil can be described as the temperature at which wax will start to precipitate from a mixture. When a mixture of 90% by volume of R-12 and 10% oil by Volume under the specified conditions.

Since the oil-soluble refrigerants lower the viscosity of the oil and affect both the pour point and cloud point. The floc point of the oil is a more important property where oil miscible refrigerants are used.

The results are used to compare the waxing tendency of the various different oils. It provides a method for determining the waxing tendency of the refrigeration lubricant. Floc point should not be confused with cloud point because cloud point is the temperature at which the wax is precipitated from the undiluted oil.

Answer:

fast

Explanation:

Because kinetic energy is equal to half the product of mass and square of velocity, increase in velocity would increase the kinetic energy as well.

Answer:

Yes

Explanation:

By definition, the equilibrium constanct, Kc, for the reaction A ⇒ 2B is

= [A]^1 / [B]^2

Substitute [A] = 4 and [B] = 2 in the equation,

[A]^1 / [B]^2

= 4^1 / 2^2

= 1

= Kc

So yes the reaction is at equilibrium.

Let's find K_c

[tex]\\ \rm\Rrightarrow K_c=\dfrac{[B^]^2}{[A]^1}[/tex]

[tex]\\ \rm\Rrightarrow 1=\dfrac{2^2}{4}[/tex]

[tex]\\ \rm\Rrightarrow 1=\dfrac{4}{4}[/tex]

[tex]\\ \rm\Rrightarrow 1=1[/tex]

Yes it's at equilibrium

Given that 4.50 dm³ of Pb(NO₃)₂ is cooled from 70 °C to 18 °C, the

amount amount of solute that will be deposited is 1,927.413 grams.

The volume of water 1.33 dm³ of water 70 °C.

The number of moles of Pb(NO₃)₂ that saturates 1.33 dm³ of water at 70 °C  = 2.25 moles

At 18 °C, the number of moles of Pb(NO₃)₂ that saturates 1.33 dm³ of water = 0.53 moles

Therefore;

Number of moles of Pb(NO₃)₂ in 4.50 dm³ at 70 °C is therefore;

1.33 dm³ contains 2.25 moles.

[tex]Number \ of \ moles \ in \ 4.50 \ dm^3 = \dfrac{2.25}{1.33} \times 4.50 \approx \mathbf{7.613 \, moles}[/tex]

Number of moles of Pb(NO₃)₂ in 4.50 dm³ at 70 °C ≈ 7.613 moles

Number of moles of Pb(NO₃)₂ in 4.50 dm³ at 18 °C is therefore;

1.33 dm³ contains 0.53 moles

[tex]Number \ of \ moles \ in \ 4.50 \ dm^3 = \dfrac{0.53}{1.33} \times 4.50 \approx \mathbf{1.79 \, moles}[/tex]

Number of moles of Pb(NO₃)₂ in 4.50 dm³ at 18 °C ≈ 1.79 moles

The number of moles that precipitate out = The amount of solute deposited

Which gives;

Amount of solute deposited = 7.613 moles - 1.79 moles = 5.823 moles

The molar mass of Pb(NO₃)₂ = 207 g + 2 × (14 g + 3 × 16 g) = 331 g

The molar mass of Pb(NO₃)₂ = 331 g/mol

The amount of solute deposited = Number of moles × Molar mass

Which gives;

The amount of solute deposited = 5.823 moles × 331 g/mol = 1,927.413 g

Answer:

101 g KNO₃

Explanation:

Molarity is measued in moles per liter, mol L− 1, or molar, M, which means that a 0.500-M solution will contain 0.500 moles of potassium nitrate for every 1 L of solution.

Well, if you get 0.500 moles for every liter of solution, and your solution has a total volume of 2.0 L, it follows that it must contain 2 × 0.500 moles = 1.00 moles KNO₃

So, what mass of potassium nitrate is equivalent to one mole of the compound?

Potassium nitrate's molar mass, 101.103 g mol− 1, tells you the mass of one mole of potassium nitrate. In this case, the answer must be rounded to three sig figs, so m KNO₃ = 101 g KNO₃

Hope this helped!

101 grams of KNO₃ should be used to prepare 2.00 L of a 0.500 M solution.

The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter.

A mole is defined as the amount of substance containing the same number of atoms, molecules, ions, etc. as the number of atoms in a sample of pure 12C weighing exactly 12 g.

Given,

Volume of KNO₃ = 2 L

Concentration = 0.5 M

Moles of KNO₃ = Concentration × volume

                       = 0.5 × 2

                       = 1 mole

Mass of KNO₃ = Moles × molar mass

                       = 1 × 101

                       = 101g

Therefore, 101 grams of KNO₃ should be used to prepare 2.00 L of a 0.500 M solution.
