Answer:

A open system

I think plz tell me if i'm wrong

Explanation:

Answer:

A- an Open System

Explanation:

Usually electrical conductors have loosely bound electrons. Materials that conduct heat are thermal conductors

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:

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:

simple

Explanation:

A transform fault or transform boundary is a fault along a plate boundary where the motion is predominantly horizontal.[1] It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone.[2]

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).

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.

Explanation:

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.
