Answer:

Non-polar

Explanation:

The way to determine if something is polar is by subtracting their electronegativity values. The two atoms in this molecule are both phosphorous which have equal electronegativity values (since they are both phosphorus). Anything minus itself will equal 0. If the final difference between the electronegativity values is less than 0.4, it will be non-polar. Since the result is 0, P2 is non-polar.

In P₂ molecule there is absence of partial charges, thus the molecule has been nonpolar.

The molecules have been differentiated based on polarity as polar and nonpolar molecules. The molecules that have been comprised of the difference in the electronegativity of the elements and develop partial charges have been termed polar compounds.

The compounds with no difference in electronegativity and absence of partial charges are termed nonpolar molecules. In the P₂ molecule, there have 2 phosphorus molecules with the same electronegativities.

Since there has been an absence of polarity in the molecule, the molecule of P₂ is nonpolar.

Answer:

Explanation:

The Kinetic Energy (K.E) of an object can be calculated as:

We are given:

K.E = 480 K

Velocity of the object = v = 8 m/s

Using the values, we get:

Thus, the mass of the object will be 15 kg.

The mass of the object at the given momentum and speed is determined as 5 kg.

The momentum of the object is calculated as follows;

P = mv

where;

m = P/v

m = 40/8

m = 5 kg

Thus, the mass of the object at the given momentum and speed is determined as 5 kg.

Answer:

184.62 ml

Explanation:

Let [tex]p_1, v_1,[/tex] and [tex]T_1[/tex] be the initial and [tex]p_2, v_2,[/tex] and [tex]T_2[/tex] be the final pressure, volume, and temperature of the gas respectively.

Given that the pressure remains constant, so

[tex]p_1=p_2[/tex] ...(i)

[tex]v_1[/tex] = 200 ml

[tex]T_1= 26 ^{\circ}C = 273+26 =299[/tex] K

[tex]T_2= 3 ^{\circ}C = 273+3 =276[/tex] K

From the ideal gas equation, pv=mRT

Where p is the pressure, v is the volume, T is the temperature in Kelvin, m is the mass of air in kg, R is the specific gas constant.

For the initial condition,

[tex]p_1v_1=mRT_1 \\\\mR= \frac{p_1v_1}{T_1}\cdots(ii)[/tex]

For the final condition,

[tex]p_2v_2=mRT_2 \\\\mR= \frac{p_2v_2}{T_2}\cdots(iii)[/tex]

Equating equation (i), and (ii)

[tex]\frac{p_1v_1}{T_1}=\frac{p_2v_2}{T_2}[/tex]

[tex]\frac{v_1}{T_1}=\frac{v_2}{T_2}[/tex]  [from equation (i)]

[tex]v_2=\frac{T_2}{T_1} \times v_1[/tex]

Putting all the given values, we have

[tex]v_2=\frac{276}{299} \times 200 = 184.62 \; ml[/tex]

Hence, the volume of the gas at 3 degrees Celsius is 184.62 ml.

The amount of 10.5 g magnesium carbonate is needed to make 5.0g of magnesium oxide.

So, option D is correct.

Given that, Magnesium carbonate decomposes on heating to form magnesium oxide and carbon dioxide as

                  MgCO₃ → MgO + CO₂

Molar mass of MgCO₃ = 24 + 12 + 48 = 84 g/mole

Molar mass of  MgO = 24 + 16 = 40g/mole

40 gram MgO is produced  from 84 gram of MgCO₃

1 gram of MgO produced  from  [tex]\frac{84}{40}=2.1[/tex] gram of MgCO₃

Therefore, 5 gram of MgO produced  from [tex](5*2.1=10.5gram)[/tex] of MgCO₃

Thus, option D is correct.

MgCl2 + Ag(NO3)2 → AgCl2 + Mg(NO3)2

The pOH of a solution : 13.756

Mass HCl=10.4 g

mol HCl (MW=36.5 g/mol) :

[tex]\tt mol=\dfrac{mass}{MW}=\dfrac{10.4}{36.5}=0.285[/tex]

Volume of HCl = 500 ml = 0.5 L

[tex]\tt M=\dfrac{n}{V}\\\\M=\dfrac{0.285}{0.5}=0.57~M[/tex]

HCl ⇒ H⁺ + Cl⁻

[H⁺]=[HCl]=0.57 M

pH= - log[H⁺]

pH=-log[0.57]=0.244

pH+pOH=14

pOH=14-0.244

pOH=13.756

Answer & Explanation:

Crest is a point in the cycle where maximum or peak amplitude exists. In another way, it is a point on the positive side of a wave where maximum amplitude exits. Trough is a point in the cycle where minimum amplitude exists.

Crest: points A and E

Trough: points C and J

Wavelength is the distance between two crests or two troughs. One example is distance between points A and E.

Frequency is 3 because there are 3 oscillations in 1 second (follow the line from beginning to point D, then D to G, the G to end).

Explanation:

Answer:

The correct answer is particles that struck the center of the atom were repelled.

Explanation:

Rutherford performed an experiment which is called the gold foil experiment. In the gold foil experiment of the Rutherford, a gold foil is bombarded with the positively charged alpha particles. The bombardment of the alpha particles shows the unexpected result to Rutherford.

He thought these particles go through the gold foil but to his surprise, some particles bounced back and some deflected after colliding with foil. On the basis of these, he suggested that there is a positive charge present in the center of an atom that repelled the positive charge of alpha particles and leads to deflection and bouncing back.

Thus, the correct answer is particles that struck the center of the atom were repelled.

Answer:

Mass of MgF₂ formed = 40.5 g

Explanation:

Given data:

Mass of NaF = 55 g

Mass of MgF₂ formed =  ?

Solution:

Chemical equation:

2NaF  +  Mg      →     MgF₂ + 2Na

Number of moles of NaF:

Number of moles = mass/molar mass

Number of moles = 55 g / 41.98 g/mol

Number of moles = 1.3 mol

now we will compare the moles of sodium fluoride with magnesium fluoride.

                     NaF       :          MgF₂

                       2          :             1

                     1.3          :        1/2×1.3 =  0.65 mol

Mass of magnesium fluoride:

Mass = number of moles × molar mass

Mass = 0.65 mol × 62.3 g/mol

Mass = 40.5 g
