The correct answer is polarizing power increase.

The polarizing power of these ions grows as they move through a period because their charge increases and their size decreases. The size grows and the polarizing strength reduces as one descends a group. These two effects somewhat cancel each other out while travelling diagonally, preventing a noticeable change in attributes. As a result, the attributes of these diagonally oriented elements behave similarly.

What is polarizing power?

The capacity of a cation to distort an anion is known as its polarization power. The term "polarizability" refers to an anion's propensity to get polarized by a cation. The charge and radius of a cation affect its ability to polarize. The relationship between charge and radius and cation polarization power. Because they are directly proportional to one another, polarization power of the cation increases as cation charge increases.

andriy [413]

Answer:

Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. ... When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. At the center, gravity pulled more and more material in.

Explanation:

When the solar system was very young, the sun was just being formed and planets had not yet been made. The solar system was mostly gas and dust.

Use the information in the table about four different electric circuits to answer the question
ycow [4]

Answer:

Circuit 4

Explanation:

To know the correct answer to the question given above, we shall determine the current in each circuit. This can be obtained as follow:

For circuit 1:

Resistance (R) = 0.5 ohms

Voltage (V) = 20 V

Current (I) =?

V = IR

20 = I × 0.5

Divide both side by 0.5

I = 20 / 0.5

I = 40 A

For circuit 2:

Resistance (R) = 0.5 ohms

Voltage (V) = 40 V

Current (I) =?

V = IR

40 = I × 0.5

Divide both side by 0.5

I = 40 / 0.5

I = 80 A

For circuit 3:

Resistance (R) = 0.25 ohms

Voltage (V) = 40 V

Current (I) =?

V = IR

40 = I × 0.25

Divide both side by 0.25

I = 40 / 0.25

I = 160 A

For circuit 4:

Resistance (R) = 0.25 ohms

Voltage (V) = 60 V

Current (I) =?

V = IR

60 = I × 0.25

Divide both side by 0.25

I = 60 / 0.25

I = 240 A

SUMMARY

Circuit >>>>>> Current

1 >>>>>>>>>>> 40 A

2 >>>>>>>>>>> 80 A

3 >>>>>>>>>>> 160 A

4 >>>>>>>>>>> 240 A

From the above calculation, circuit 4 has the greatest electric current.

Determine the concentration of sulfuric acid that needed 47 mL of 0.39M potassium hydroxide solution to neutralize a 25 mL sampl
Ugo [173]

0.73 M is the concentration of sulfuric acid that needed 47 mL of 0.39M potassium hydroxide solution to neutralize a 25 mL sample of the sulfuric acid solution.

Explanation:

Data given:

Volume of the base = 47 ml

molarity of the base= 0.39 M

volume of the acid = 25 ml

molarity of the acid =?

For titration reaction between acid and base, the volume or molarity of any of the base or acid can be determined.  The formula used:

Macid X Vacid = Vbase x Mbase

Macid = \frac{Vbase X M base}{V acid}

putting the values given in the rearranged equation above:

Macid = \frac{0.39 x47}{25}

           = 0.73 M

The concentration of the sulphuric acid needed is 0.73 M.
