Suitable hypothesis for the experiment is as temperature increases rate of reaction also increases.
<h3>What is rate of reaction?</h3>
Rate of any reaction gives idea about the speed of the completion of that reaction.
Rate of reaction will be affected by many factors are some such factors are:
- Dependent variable: Rate of change of the chemical species which are present in the reaction is the dependent variables.
- Independent variable: Independent variable is temperature as it does not depends on the rate, in spite of this rate depends on temperature.
- Controlled variables: Environment of the reaction, amount of catalyst, light exposure to the reactions are the controlled variables as it depends on the requirement of the amount of product.
Hence, hypothesis is as temperature increases rate of reaction also increases.

- The charge distribution in a CH₄ molecule is symmetric.
- CH₄ molecules are nonpolar.
<h3>Explanation</h3>
A CH₄ molecule has four C-H bonds. Each of the C-H bonds is weakly polar. However, the molecule has a tetrahedral shape. The shape itself is symmetric.
As a result, charges on the four C-H bonds have a symmetric distribution. They cancel out within the molecule. Overall, the molecule is nonpolar.
Answer:
E = 16 J
Explanation:
We have,
You put scruffy can run up to 2 m/s on his fastest days scruffy has a mass of 8 kg
It is required to find the maximum kinetic energy on his fastest days. If v is the velocity, then kinetic energy is given by :

Plugging all the values,

So, the maximum kinetic energy on his fastest day is 16 J.
