The oxidation number if eah of the elements is as follows;

  • Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
  • Oxidation number if hydrogen is +1 on both sides
  • The oxidation number of oxygen is -2 on both sides
  • The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.

<h3>What is a redox reaction?</h3>

A redox reaction is one in which there is a change in the oxidation number of the reactants from left to right.

Let us now consider the oxidation  number of each element from left to right;

  • Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
  • Oxidation number if hydrogen is +1 on both sides
  • The oxidation number of oxygen is -2 on both sides
  • The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.

How many electrons pass through a 20-ohms resistor in 10 min if there is a potential drop of 30 volts across it?
tangare [24]

The number of electrons passes through 20 ohms resistor in 10  minutes is 5.625e+21.

<h3>What is a resistor?</h3>

In an electronic circuit, a resistor is an electrical component that limits or regulates the flow of electrical current.

Given, the resistance is 20 ohms.

The potential difference is 30 volts

Time is 10 minute

By the formula of current

\rm I = \dfrac{30}{20} = 1.5 \;C/s

The charge flowing through the resistor is 1.5 C/s

1 electron charge is 1.6e+19

Now, the number of electrons passing through a 20 ohms resistor is

\dfrac{1.5}{1.6e+ ^2^1} = 0.9375e+^1^9

In 10 minutes

0.9375e+^1^9 \times 60 \times 10 = 5.625e+^2^1

Thus, the number of electrons passes through 20 ohms resistor in 10  minutes is 5.625e+21.

The property taxes in a town decrease as the distance from the local elementary school increases. The greatest property taxes ar
Ann [662]

To solve this question, we will need the help of the picture attached:


1. According to this, every 101010 miles from the elementary school (Assuming the school is in point 0 of the line) the property taxes decrease 0.5%.


2. We also know that the greatest value in property taxes is 4.5%, and this decreases every 101010 miles.


So, if we draw a line divided in sections of 101010 miles and taking into account the data given, we have to sum each 101010 miles section until we get to the property tax value of the house, which is 3% in this problem.


Then, the distance from the school to the house, taking into account the 0.5% decrease with the distance is:


303030 miles
