Protons are always the same as your atomic number.

Mass# - atomic # = neutrons

Atomic# - charge = electrons

To get your mass# you need to add the protons to the neutrons = Mass #

To get the charge look at the difference between the protons and neutrons.

When the following redox equation is balanced with smallest whole number coefficients, the coefficient for nitrogen dioxide will

Phoenix [80]

In a redox reaction, electron could be lost or gained. The coefficients in the balanced redox reaction are; 1/2, 5, 1, 5, 2, 1.

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

A redox reaction equation shows the species that were oxidized or reduced in a redox reaction. In this case, we are asked for the coefficients in a balanced redox reaction equation.

We must recall that five electrons were lost/gained in the process hence the balanced reaction equation is;

1/2I2 + 5HNO3 -----> IO3^- + 5NO2 + 2H2O + H^+

The coefficients in the balanced equation therefore are; 1/2, 5, 1, 5, 2, 1.

A train in Japan can travel 813.5 miles in 5 hours

Anastaziya [24]

Answer:

162.7miles/hr

Explanation:

Given parameters:

Distance covered by the train = 813.5miles

Time taken = 5hours

Unknown:

Speed of the train = ?

Solution:

Speed is a physical quantity.

It is mathematically expressed as;

Speed = $\frac{distance}{time}$

So, input parameters and solve;

Speed = $\frac{813.5}{5}$ = 162.7miles/hr
