A covalent bond means shared electrons between atoms. This is similar to kids sharing markers because the markers (electrons) are being shared between the kids (atoms). Covalent bonds are different than this metaphor because 1) the electrons are constantly moving about while the kids can steal and keep the markers and 2) the electrons and atoms are physically smaller
Answer:
meteor
Explanation:
The most logical identification of a "shooting star" is a meteor. A meteor is basically any material from outerspace that falls to Earth. The main characteristic of a meteor is that from our point of view on the surface of the Earth it looks like a shooting star because we see a streak of light behind it. This light is simply dust and rock from the meteor burning up as it enters the Earth's atmosphere, leaving a "tail" of light behind it. Which to us looks like a shooting star.
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.
