4 0

Answer:

<h2>The coefficient of the diatomic oxygen has to be 2.</h2>

Explanation:

The balanced reaction should be like this: 2O_{2} + CH_{4} = CO_{2} + 2H_{2}O

So, as you can see, balance mean that molecules in the reaction has to be equal, the amount of element involved has to be the same, due to the Conservation of the Mass Law.

So, Hydrogen and Oxygen are not balanced in the given expression, that's why we need to add those coefficients.

A discus thrower throws a 1.6kg discus at 25m/s what's the kinetic energy?​
Ilya [14]

Answer:

<h2>500 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2} \\

where

m is the mass

v is the velocity

From the question

m = 1.6 kg

v = 25 m/s

We have

k =  \frac{1}{2}  \times 1.6 \times  {25}^{2}  \\  = 0.8 \times 625 \\  = 500

We have the final answer as

<h3>500 J </h3>

Hope this helps you
